Hi folks,
I'm looking at different accounting/business management packages for use in my small business, and i was excited when i found how comprehensive and easy to install opentaps was. However, it is a daunting application for the beginner, and it leads me to ask: is it asking for trouble trying to use it as a small business accounting package? My requirements are fairly simple: invoicing (services only, no inventory), general ledger, and GST tracking for the Australian tax system. I'm a novice Java developer, so i can get through most basic problems OK, but understanding the framework is a bit more complex an undertaking. Am i just creating work for myself thinking that i can use OFBiz/opentaps for my small business? Thanks in advance, Paul <http://paulgear.webhop.net> -- Did you know?

Hi Paul,
I believe I'm currently doing it for a small business as well. You'll need to customize. Customization in this case involves defaulting many values and code execution paths for a more condensed workflow. That is, you can cut out some unnecessary steps in the workflow and also auto-populate default values for some fields (or leave them blank and unused). I propose that we work together on this? I have yet to hit the accounting and GL side of things. I have figured out the ecommerce (PO, SO) and product configuration side of things, though. And also manufacturing, because my boss does manufacture stuff. You'll find that being a novice Java developer is ALL you need to be, the framework is that easy to use. Well, you also need acute reverse-engineering skills because the only way you'll find out how things work is by diving into the framework source codes (see GenericDelegator.java for entity-related functions). No docs. Community is too being moving OFBiz forward rapidly. In fact, you may find it easily initially to use Java instead of Minilang. Java is a lot more documented than Minilang. Tell you what. I can offer you very quick answers to "how do I do this or that". I'm a reverse-engineer by trade; I have small crack teams that mathematically take apart legacy system codes to break vendor-lock for my clients. So, figuring out OFBiz, given that it's opensource no less, is really... an interesting exercise, not a tedious impractical one. You can help me with your accounting knowledge. (Yes, help me!! I beg you!) How about that? One warning, though. There are quite a few bugs in OFBiz. They're small issues if you can dive in to fix them yourself. But if you're waiting for the community to fix them, you could be looking at weeks before a patch goes in, especially for non-trivial fixes that take time to review/audit. I'm currently holding quite a number of fixes in-house, not yet reviewed by community and merged back into OFBiz. I'm deploying a customized system for my boss inside of 1 month. And he has quite a bit of customizations to do, particularly for the manufacturing side of things. Oh, the Manufacturing module is very feature-rich (thanks Jacopo!), just that my boss has special needs. I'd say we could work together and customize OFBiz for you inside of 2 weeks?

Hey Paul,
You will probably have better luck with your opentaps financials questions over on the opentaps sourceforge forums. http://sourceforge.net/forum/?group_id=145855 The guys working on that component likely follow both mailing lists, but I would imagine they follow that one a bit more religiously and can give you a faster response there. There have been quite a few discussions on many of the topics you're interested in on the OFBiz mailing lists as well. You can search for the topics individually. Nabble is a great site for these aggregations and seeing the threads in context. Here's the link for the OFBiz portion of nabble. http://www.nabble.com/OFBiz-f2740.html There was quite a discussion a little more than a year ago regarding using Quickbooks via SOAP with OFBiz as well. Depending on your needs you may consider that route as well. As far as creating work for yourself, a quick answer is, perhaps. A longer answer is that it's likely to be time well spent. You'll end up with generally a better understanding of your _actual business needs as well as many ideas on how to better automate your business around what your company's strengths are and what your customers needs are. There have been numbers passed around about the size of a business that OFBiz is beneficial for and that's at about 2 million dollar US + [Note: the size breakpoint may simply be the size of a company that likely has a budget large enough for a consultant to make money on :-) ] You may not need to be doing that much business today, but if you're genuinely aspiring to that size, you'll likely benefit in doing things in an ERP/OFBiz style. If you're needs are just to keep track of some things kind of unofficially, you may also find some benefit from the OFBiz framework and dumbing down a lot of the other components. The learning curve in OFBiz is somewhat steep because it's integrating several tools and concepts into one thing. The tools individually are rather straight forward and there's plenty discussion and documentation regarding them on various sites. Most of those sites are linked off of ofbiz.apache.org. In addition, the user and development mailing lists are quite busy so you can usually get an answer pretty quickly there as well regarding specific questions on using the tools. Hope you find this helpful, Chris --- Paul Gear <[hidden email]> wrote: > Hi folks, > > I'm looking at different accounting/business > management packages for use > in my small business, and i was excited when i found > how comprehensive > and easy to install opentaps was. > > However, it is a daunting application for the > beginner, and it leads me > to ask: is it asking for trouble trying to use it as > a small business > accounting package?

Hi Jonathon and Paul,
Could I dive in here and say I'm currently trying to get a working model up and running that I could demo to small business clients in the UK. OFbiz looks so beautifully designed from the ground up, streets ahead of the competition and adaptable to almost any situation from running a one-man consultancy to a multinational enterprise. It looks like the most awesome super-car you've ever seen. I can't believe everybody won't want one. As Jonathon says, the community seems entirely focussed on moving forward rapidly and winning the next Le Mans. Which is how it should be. Imo this explains the lack of docs and the small bugs. The mass of available documentation is actually almost as awesome as the framework itself. Problem is that it is all aimed at engineers who need to understand how it works ... not how to work it. Enough workshop manuals to fill shelves in the garage, but no simple driver handbooks you can put in the glove compartment. This is a very fundamental difference. An entirely opposite point of view. Try talking to the average driver about the thermodynamics of combustion and they glaze over in seconds. They neither need nor want to know. They simply want to drive it. They pay the garage to take care of all that for them so they can free themselves up to deal with other things - like where to drive to. It's the little, superficial things that are most important. How does the door latch sound? Where is the gear shift and indicator switch? How often does it break down? This is true for all levels of users. More so in fact for the President of a large Corporation to whom image arriving at the golf club is everything, than to the small businessman in the street who accepts he may have to get his hands dirty occasionally. Winning the Le Mans is obviously a huge selling point and an essential place to start. In those circumstance, a door latch which needs a knack to open, the absence of a drivers handbook and the need for team of mechanics to tune it before every race is absolutely par for the course. And a racing driver who complains about such things will - quite rightly - be quickly shown the door. But for the average driver in the street it's exactly the opposite. One sticking door latch, one miss-start, one breakdown on the first test drive and they've had their one bite of the cherry and ain't never coming back for more. Imo this is the only problem I'd like to see solved. I started out a few weeks ago trying to point out that this list is more for users in overalls at the pit stop than drivers in business suits on their way to the office. Imo a forum for user-drivers rather than user-engineers would help focus the view from the other end of the telescope and prevent discussion of such superficial issues from clogging the inboxes of the rocket scientists who really need to be concentrating on getting us to Mars. I personally would like to contribute towards the development of some kind of drivers handbook. But if I can't get a working model going for myself then it's hard to know where to start.

Ian,
Amen! Yeah, God is good. OFBiz is good. Both can be hard to understand. But I do believe that both are loving, very loving. Amen. If there's any way we can all help each other (Paul, Ian, Jonathon), let me know.

Er, Ian. I forgot to mention this.
The docs for engineers aren't too comprehensive either. Try putting your best Java developers into picking up OFBiz. Take the screen widgets and form widgets for example. See how they fare. Like I said, Java is more documented than OFBiz-specific technologies. BUT.. but it's entirely possible to use Java only, plus non-OFBiz-specific technologies like Freemarker for front-end development convenience, and to skip Minilang and screen/form widgets to a large extent. Non-OFBiz-specific technologies are generally better documented since their developers focus develoment time solely on those techs, like Freemarker (front-end tool) developers don't delve into entity engines (backend tools). As I was telling my boss, it's actually easier to hire Java programmers than to hire Minilang or screen/form widget programmers. So, beware of the implications. Say I code customizations for you in Minilang and screen/form widgets, using almost or entirely zero Java. Future tech support could be an really hairy issue for you. BUT... at some point (I can't guarantee when), Minilang and screen/form widget docs will be complete, audited to be comprehensive, etc. You'll then probably find that programming in Minilang is more cost-effective than in Java. (Either that, or I get paid by someone to completely reverse-engineer and document all of Minilang and screen/form widget in a reasonable timeframe --- say a month. Not an impossible task, just a mountain of Java codes, is all). For now, Java is perhaps your best bet. To the other folks in overalls, I've been meaning to ask this. Is there any way at all to insert debug messages inside of Minilang and screen/form widget codes? I find it easier to debug Java codes for now. Jonathon Jonathon -- Improov wrote: > Ian, > > Amen!

Jonathon,
What are you finding so confusing about minilang that is not covered here http://docs.ofbiz.org/x/GAM ? This document has been improved upon recently, but the bottom half has been accessible from the ofbiz.org site for two years that I can attest. Coming from someone who had ZERO java experience starting with OFBiz (me) I find the elements are rather self explanatory. It's also not as if there aren't plenty of examples using each one. I have no idea how well minilang would hold up to creating various kinds of other programs, but for writing business logic, it's pretty straight forward. If you're not finding that to be the case, please ask questions there are plenty of people here more than willing to help clarify. Also, documentation doesn't write itself. If you find something that didn't work as expected or a task was difficult to accomplish but you eventually accomplish it, do a short write about how you got from point A to point B and drop it into the wiki on docs.ofbiz.org or write it to the mailing list and ask if someone can find an appropriate place for it. There's a funny point in learning OFBiz. You start out looking at it as this huge monstrosity that's just too much to figure out and you get frustrated with the lack of documentation available (even given the sites linked off of ofbiz.apache.org and the tens of thousands of mailing list posts available and the number of video tutorials available). But you start playing with it a bit, and you pass an "aha" moment. You don't realize the moment that you pass it but when you look back and think "how can I make the learning curve easier for the next guy", you realize everything was there, and it's difficult to figure out what you can add to those websites that could make it any clearer. I digress, just ask questions. If you're unable to find your answer on a first pass through nabble and on the ofbiz.apache.org ask the question to the mailing list and someone may be able to find the right document for you a bit faster or clarify a point in a document that may be a bit unclear. --- Jonathon -- Improov <[hidden email]> wrote: > Er, Ian.

Ian, Jonathon,
I definitely don't agree with treating Java is your language of choice as a way to avoid learning Minilang, here's some reasons why... 1/ Minilang is far quicker to write. 2/ Minilang is much more limited in scope, so less danger of... 2a. Writing unidiomatic code 2b. Writing buggy code 3/ Being a simpler language, minilang can be handled by far more junior personnel, and in some cases, I've seen non development staff being fairly productive. 4/ Java developers are easier to hire, but not ones with a good understanding of the OfBiz API. 5/ Learning minilang is a fast-track route to adopting the OfBiz developer's mindset. 6/ So much functionality is already implemented in minilang that you ignore it at your peril. 7/ When you finally have to adopt Minilang you'll have a load of unmaintainable java legacy. This will no doubt seem more and more cryptic as time goes on. I could probably go on... This type of approach breaks the golden rule when adopting something as large as OfBiz, that is, read read read!, learn learn learn!, and only then should you think of letting yourself loose on the code! You'll thank yourself later! No doubt various people will counter this with a whole lot of personal dislikes about minilang, but I'll be surprised if any of these people have been using OfBiz in anger for any length of time. Sorry if this seems a little condescending, but I've seen this kind of argument in my consultancy work several times, and the resulting costly dodgy java or furious back-peddling that results from it. - Andrew On Thu, 2007-01-18 at 19:38 +0800, Jonathon -- Improov wrote: > Er, Ian.

In reply to this post by Andrew Sykes
Andrew, Chris, Ian,
I would definitely choose Minilang over Java, if I didn't have a pressing "do it this minute" schedule. It is definitely the right step forward. I tried Minilang for a while, then realized there ARE some constructs I can't quite do like I would with Java. Same for screen/form widgets. I posted a short question asking if there's any docs for screen/form widgets. No response thus far. But I've since learned what env-name, map-name, etc mean. Not by docs I can find, but through the widget framework Java sources. Simple concepts like "how do I extract a field value and put it to a variable for later use", or even "how do I create a variable for computation" required some digging into widget framework Java sources. So, what did I do? I got the job done. Java works. Minilang can wait. :P Screen/form widgets can wait (I used a Java service attached by an ECA). Did I do a messy buggy Java routine? I'd ask you the same question. With some basic programming principles, it's not difficult to write reusable extensible code (see the mutable checks sequence I wrote for http://issues.apache.org/jira/browse/OFBIZ-627). Sure, I'll eventually find it easier to do things in Minilang. Many Minilang constructs are direct clones of Java functions anyway, so converting from one to the other and back won't be so tough. But it's the variables, scope, "where did that variable's value got stomped" problems that put the brick wall up for me. So, as things stand now, I (being a Java programmer of sorts), found it easier in Java. A simple Java programmer like me knows certain "tricks of trade" to figure out the structure of Minilang or widget XMLs. But what about non-programmers? > 6/ So much functionality is already implemented in minilang that you ignore > it at your peril. Anyway, I am able to tap all of Minilang's features using Java alone, so I do get best of both worlds. :) Actually, to be fair, Minilang isn't so bad in terms of docs (by now? recently?). See http://ofbiz.apache.org/docs/minilang.html . I was really struggling with widget XMLs. Right now, my project is moving ahead. And that's what counts. Sigh. Couldn't there be a time when we abolish work, and everybody does things simply for exploration and science? Chris, > Also, documentation doesn't write itself. If you find > something that didn't work as expected or a task was > difficult to accomplish but you eventually accomplish > it, do a short write about how you got from point A to > point B and drop it into the wiki on docs.ofbiz.org or > write it to the mailing list and ask if someone can > find an appropriate place for it. I'd be fired! I did try to get quickstart advice from mailing list, remember? But now that I've posted questions, waited for response, dug in myself, and found answered my posts myself, I can't find much time left to write up those docs. I don't even have enough time to submit my enhancements and bugfixes! Yes, bad bad programmer, not very opensource-spirited. But like I said, I can be a very opensource-spirited non-programmer (after being fired), or I can just "do my job" and hope I can swing back some time to contribute. And I'll definitely want to do something for OFBiz. As I told someone here before, I'm thoroughly enjoying OFBiz (like the manufacturing and product Virtual BOMs stuff done by Jacopo?). > There's a funny point in learning OFBiz.

Hindsight is always easier. I know what you mean, Chris. It's like we stare at some seemingly random numbers scrolling through screen, we think it's noise. But after we spot the patterns, we wonder how we didn't see it before! I can't learn "The Matrix green downward-scrolling font" inside of 1 week. I need to get into the Matrix and do some work RIGHT AWAY (like run the nice noodle restaurant at the corner). So, instead of reading those green fonts, I pulled out the Matrix engine and started plugging away at the interfaces. (Aha! So touching this and that interface gives me very good soup noodles!).

Andrew,
Yeah, we all tried. Maybe I have my head so buried in Java I can't see the simple methods in Minilang. For now, given a hot-soup mix of problems from screen/form widgets and problems with some constructs in Minilang, I'm forced to drive things forward this way: Use Java services but leverage every convenience method in Minilang. Once I'm done with this current project (or when I'm fired), I can come back here to "explore and contribute". Oh well. Back to work. :( ... :) ... :/ I still say that OFBiz rules! And I intend to prove my instincts right, after I'm done with project. With regards Ian's comments, I personally like winning the Le Mans (less docs, more progress, but then why do bugfix rates seem to slow down recently?). I'm a wannabe race car driver who takes apart race cars, so I don't quite care for driver's manual in glove compartment. But then, I'm also NOT known for having a forte in amassing world-wide adoption for OFBiz, nor can I be held responsible for OFBiz's future popularity. :P Jonathon Andrew Sykes wrote: > Jonathon, > > Ok, well, I tried ;-) > > - Andrew > > On Thu, 2007-01-18 at 21:51 +0800, Jonathon -- Improov wrote: >> Andrew, Chris, Ian, >> >> I would definitely choose Minilang over Java, if I didn't have a pressing "do it this minute" >> schedule.

Jonathon,
One final point on the subject, just in case you don't already know. If, as it seems from your email, there are just a few issues barring you from getting productive with minilang, you could perhaps use a call-bsh tag in the minilang to handle the odd situation when your minlang experience is letting you down. This isn't ideal for every situation, so be judicious, but it might just help you on the way to surmounting the minilang hurdle! Best of luck with it! - Andrew On Thu, 2007-01-18 at 23:40 +0800, Jonathon -- Improov wrote: > Andrew, > > Yeah, we all tried.

A clear roadmap would be most useful so that the essential stuff gets read first. And yes, there are already How to documents, architecture documents, but there is too much to read plus every document starts with a brief resume of OFBiz rather than getting down to the business at hand. Basically it appears that every document has been written to stand alone and therefore feels the need to fill in the back ground on OFBiz. I haven't yet read a great deal of the available documentation, but there is a trend there. Please don't take offence at these comments, they are only intended to help. I also find that there is a lack of structure in the documents in that there tends to be paragraph after paragraph of text which is neither reference nor tutorial. And as I progress along the road to OFBiz heaven I will try to document my path. In the mean time it might be useful to thrash out a style and structure to the whole documentation suite. Heck I know this can be difficult in the open source environment. I would favour a wiki approach to doing documents provided the wiki is restricted to named members to stop spammers wrecking it. In the wiki, users should use a colour, perhaps blue to indicate a question or need for further detail in the flow of the document and the remainder of the contents in black. I am quite willing to start up a tutorial document if you are all willing to contribute to it with David acting as umpire. Kind regards, Andrew Ballantine. -- No virus found in this outgoing message.

Jonathon,
Your words of comfort are much appreciated. My instincts tell me OFbiz rules and I suspect God may too. So Amen from me too! Can we all help each other? It would be great if we could. But I think I need to make my position clear at the outset, to avoid possible disappointment further down the line. I've been working with computers on and off since the late 60s and have had to learn to hack various languages, from Algol through to php. But it was never my major area of expertise. I never got into C, so OOP and Java is still entirely new territory for me. Java, Minilang, or Freemarker, I'd have to learn them all from scratch, will always be miles behind everyone else, and could be in serious danger of being more of a cost than a benefit. I've just starting reading Bruce Eckel's Thinking in Java and starting thinking, maybe there just aren't enough years left to get up to speed on all this? This could be either a major weakness or a strength, depending on where I'm standing and what people might be relying on me to do. From what I've seen on this group over the past few weeks, there is no shortage of top class engineers who I have no doubt could strip down the engine and stick it back together again working better than ever, before I'd finished making the morning tea (or coffee, depending on what side of the pond you're on. :) I'm enough of an engineer to know how utterly irritating it is to have people whittering on about irrelevancies like sticking door locks when you've been up all night regrinding the cylinder head. But I've also been down that road enough times to know how crucial it can be to have someone fresh to take over, to wipe the grease off the bonnet, polish the chrome work and wheel it out onto the forecourt, after you've done your bit and just need to go home to bed. So I guess what I'm saying is that, for the moment at least, I'm better off leaving the engineering to the experts and focussing on what the average driver needs to see. For the past few years I've been installing Open Source e-commerce for SMEs. It's a huge and expanding sector. 150,000 members on osCommerce and Zen Cart forums alone! With up to 2,000 online at any one time! But the problem they are all now facing is, now they have a successful website, how do they integrate the back end with in-house accounting and POS? Which is how I discovered OFbiz in the first place. There are many points that come out of this. Too many to properly discuss here. First would be a huge potential market with installation fees of $3K upwards, and with very little heavy engineering required at all. Store owners care mainly about the look of their shop windows, the learning curve for their staff, reducing staff overheads and the reliability of the whole thing, and are prepared to pay for it. After a while they start to understand the benefits of tuning the engine, which is where the heavy engineering work kicks in. But this is something they will not even contemplate until they are confident they have a solid vehicle that will take them reliably from A to B. Second would be how the structure of these forums cultivate many levels of users, from Formula One engineers all the way through to those who don't even want to fill up the windscreen washer themselves. And this is only the tip of the iceberg. For every one member on these forums there are 9 others who can't even handle the log in and just want somebody to take care of it all for them. I care deeply about Open Source and want to see it grow. I understand why Formula One racers might not see what weekend drivers and glove-compartment handbooks have got to do with them. My point is that a wider user base increases the market, the need for all levels of mechanics, and the bargaining power of the top class engineers. If anybody thinks this make some kind of sense, please let me know. Ian Jonathon -- Improov wrote: > Er, Ian. I forgot to mention this. > > The docs for engineers aren't too comprehensive either.

Andrew (Ballantine),
As with everything OfBiz, progress is dictated by demand. With adoptees coming from such varied backgrounds and with such disparate requirements. It would be hard to create such a roadmap that would be relevant to all. Given that problem the obvious solution is to create free-standing documents that allow people the entry point of their choice. The key to success isn't where you enter, or how you progress, but rather that you do it in a thorough manner. So take a part of the code that is of interest to you (you'll need relevance to stay motivated) and then work through artifact by artifact making sure you read all the free-standing documents you can lay your hands on as you go of course! I'm not advocating that you avoid creating a roadmap, in fact I'm sure lots of people would be very grateful to you. But in the absence of one, the steep learning curve doesn't need to be addressed in a hap-hazard manner. I hope that helps... - Andrew (Sykes) On Thu, 2007-01-18 at 16:34 +0000, Andrew Ballantine wrote: > Chris Howe wrote: > > >There's a funny point in learning OFBiz.

Ian,
Java is a beast! Minilang is a simple business logic language. The average java book will run into hundreds of pages, while minilang docs can be read in an hour or two. Jonathon is using java because it is familiar to him, if you're not familiar with java, don't break your back by insisting on using that as your entry point to OfBiz. It's like trying to enter a building via the window on the third floor because that's the way the window cleaner guy told you to go ;-) - Andrew On Thu, 2007-01-18 at 16:46 +0000, Ian McNulty wrote: > Jonathon, > > Your words of comfort are much appreciated.

Ian,

We'll let each other know where we need help. > I've just starting reading Bruce Eckel's Thinking in Java and starting > thinking, maybe there just aren't enough years left to get up to speed on all > this? Never enough years to speed in every direction. Just get to where you wanna be. I'm not exactly a programmer myself, Ian. Do I know all of Java? Probably just 1% (well, ok, I did know 99% once). PHP? Maybe 5%. But the level of my knowledge depends on "what's on my plate at the moment". I have a problem, too. I probably won't pass many programmer tests. If I do happen to score well, it's because I worked on reverse-engineering my memory faculties, not the programming topic at hand. I went through school studying my learning faculties rather than the topics at hand. Yeah, shame on me. But you can say the same of many Singaporeans! (Dispassionate, robotic, relentless bunch of soulless creatures.) What I'm saying is you, given your prior engineering experience plus some sense of adventure and clever experimentation, can more than pick up any concepts or tools you need to work OFBiz. Probably more than I can. I'm just a simple reverse-engineer (problem-solver in general), not a real engineer. I'm also one of those "average weekend drivers", not just someone in overalls. Just focus on "whatever is relevant to you at the moment", and you'll get started quick. I can try to show you how if you'd like. Try my methods of picking up OFBiz or anything in general. Won't hurt (I think). Take Andrew Sykes' advice to Andrew Ballantine: "take a part of the code that is of interest to you (you'll need relevance to stay motivated) and then work through artifact by artifact". I believe that you'll be customizing OFBiz within a day of research, just like I did. Just like many folks here did, I believe. Join us! (or *hynotically* "join... us... join... us..."). Heh. Well, my boss (and previous bosses) will probably tell you I can be irritating when I kept trying to make a software engineer out of him. But I'm seriously telling you that OFBiz is a solid framework you can easily build on/with. No kidding. We just need to get the documentation and user manuals in place... > So I guess what I'm saying is that, for the moment at least, I'm better off > leaving the engineering to the experts and focussing on what the average > driver needs to see. That's alright. You can help to testdrive and complain! I love complainers!

We'll need a really solid effort to do all that, multi-tiered forums and all. Lots of work in forum moderation (but sure, we can recruit solid volunteers to help in every stratum). And then OFBiz might become like MySQL. Or sellout eventually like Compiere? OFBiz's Minilang (coupled with widget XMLs), when properly documented, will be an extremely strong pull factor. If we could somehow breach the divide between developers and users, OFBiz will certainly be wildly successful and widely popularized virtually overnight. Argh. Last ounce of energy. 2am. Later.

In reply to this post by Andrew Ballantine
Andrew,
I agree with everything you're saying here. I managed to get the engine started on both Windows and Linux before I even knew of the existence of this mailing list. So the OOTB start-up part of the handbook is largely all there. Trouble then was figuring out how to get it into first gear. Hitting the workshop manuals and the mailing lists, one message quickly became clear. If you want to get this baby out on the road you're going to need an engineering degree. As it happens, I have a couple of those, but not in OOP. Which kindof leaves me a bit up OFbiz creek without a paddle :) > A clear roadmap would be most useful so that the essential stuff gets read > first. My feeling entirely. I'd like to contribute by helping to get something like that going, but where to start? > And yes, there are already How to documents, architecture documents, > but there is too much to read plus every document starts with a brief resume > of OFBiz rather than getting down to the business at hand.

That explains why I have no problems getting started, but can't get out of first gear. > Please don't take offence at these comments, they are only intended to help. > That's such an important point. Imo what we need is a more robust kind of forum where we can thrash-out these kind of front-end problems without risking stepping on the toes of those who are already up-to-their ears working on more delicate matters of engine design. > I also find that there is a lack of structure in the documents in that there > tends to be paragraph after paragraph of text which is neither reference nor > tutorial. What struck me first is actually how literate and accomplished the documentation is in comparison with other more mainstream Open Source projects like osCommerce for instance. Which makes it all the more difficult to understand why, several week later, I'm still stuck like a rabbit in the headlights. Entranced by the power of what I see coming at me, but with no idea where to jump next. Which is what makes me think you may be onto something here. > And as I progress along the road to OFBiz heaven I will try to > document my path.

I keep thinking of something I was taught at the very beginning of my science training. That everything should be written-up in a form that assumes no prior knowledge of the speciality at hand. This is an ideal that can never be completely achieved. Not in this life anyway. Only Allah makes things perfect. But it's the trying that makes the difference. It has to be admitted that this seems to have gone out of fashion in recent years, which might be just one reason why we seem to have thrown the baby out with the bathwater in the western world at least, and science departments are closing down at a rate of knots to be replaced with media studies departments aimed at producing more Big Brothers. And we all know where that leads! Not the place to be discussing these things I know. But just one of the trends I would like to try and help to reverse. Please let me know what I can do to help to move what you're suggesting on to the next step. Best, Ian |
