ofbiz on mobile & embedded devices

Hi All,

We are quite new to ofbiz but feature wise it seem to have almost all
the functionality that we need. But there are few issues which we are
not sure on how to resolve.

Requirement here is to build a client application based on ofbiz
framework which is targeted to mobile devices and embedded devices. So
the first issue is framework's size itself, which quite huge for
mobile devices. Please suggest on how to reduce that to as small as
possible. If not, then at least can just the POS client part of it be
extracted and made run on mobile/embedded devices?

Secondly, since it has to on run mobile devices we need to compile it
using j2me, but that not not happening. Please suggest on how to do
that or if there is any other implementation of Java SDK that can
help?

Thanks in advance and looking forward your replies.

regards,
Tony Marcus

Re: ofbiz on mobile & embedded devices

You would be better off Keeping OFBiz on a server and create a mobile
device portal in OFBiz. In other words, just have the device browse OFBiz.

Re: ofbiz on mobile & embedded devices

Thanks for the suggestion, Adrian.

Thats what we already have as a backup plan but then we won't able to
leverage the functionalities that ofbiz gives ootb including data
sync'ing. I know ofbiz is a server kind of thing but can't we have
some kind of smaller/reduced ver. of it which can run mobile devices?

There was a 1st attempt some years ago: specialpurpose/hhfacility it's far from what you can have now on mobiles

If you are looking for POS on such devices, then you should rather have a look at WebPos than POS which is really designed for Point
Of Sell

I guess you could use jQuery Mobile or of course plenty of other tools...

Re: ofbiz on mobile & embedded devices

Thanks for info. tips, Jacques.

I suppose the WebPOS of OFBIZ will have to run a ofbiz app-server and
all the mobile client will access it through Internet by any means,
right!! but here we have scenarios where the mobile-clients can in
disconnected mode (due to diff. reasons). How to tackle such
situations?

Please guide.

best regards,
Tony Marcus

Re: ofbiz on mobile & embedded devices

this has been a problem since the days of multiuser databass.
I recommend you steer away from having disconnnected system.

Re: ofbiz on mobile & embedded devices

I understand your apprehensions BJ, but the disconnected-mode is one
of the main requirements/features that my client wants to have built
in to his project so we are really looking towards having it worked
out. Any suggestion/clue/hint in this regard will really be helpful
for us.

The POS is built to work in such situation. But it's really built around JavaPOS and I don't know if you can adapt it to this use
case. Because of course it needs a DB (hence a hard disk) and at the very least 256 MB of RAM (not sure 256 will even be sufficient)

Re: ofbiz on mobile & embedded devices

Hi Jacques,

Can we segregate only POS application from whole Ofbiz code, so the overall
size is reduced !!

Jacques, I had a look into source-code of the hand-held facility but
didn't get much of idea. May be its my rookie approach, but is there
some kind of doc. that can help me out on this?

Well Jacques, this is one our plan-Bs to have a mobile-client built
from ground-up around jPOS (since its distribution jar size is also
very small i.e. ~700KB, though not sure again if it supports mobile
devices) in case ofbiz thing doesn't work for us. Please suggest!!

I don't think so, it depends really on OFBiz framework and applications

In reply to this post by tony marcus

I think you should go this way. Using OFBiz POS embedded in a mobile seems impossible nowadays.
You may reuse some part of the POS code, not sure...

Also the hhfacility is a simple webapp, so not what you are looking for.

Hi Tony,

hhfacility is more a specific webapp for the hand-helds, with a
decorator designed for small screens.
Once again, we are on a web application, not a native one. OFBiz has not
been written for begin run on smartphones or anything, but on server.
Except the POS, which has a synchronization function.

If you want to make it work as a native app, then you'll have to write
it from scratch...

Cheers,

Re: ofbiz on mobile & embedded devices

Thanks Erwan, Jacques, Adrian, Freeman for the info and suggestions
that you guys shared. I guess thats quite a lot of insights that I got
here and now suppose this will give us some food for thought and see
on how to approach on our requirements.

thanks again and regards,
Tony Marcus

Re: ofbiz on mobile & embedded devices

you can run complete ofbiz POS on a 7 or 10 in tablets running Linux.
Not sure if Droid supports java SDK. I use these but they are connected
via wifi or 3G.

if you want to use Droid OS then you will probably have port Open JDK to
the droid. All this is beyond this maillng list, I think.

then you can use the sync for updating the main ofbiz when the devices
can hook up like the end of day.

you will have to make some decisions in regards to record syncing but it
is about the only way to use ofbiz.

RE: ofbiz on mobile & embedded devices

In reply to this post by Jacques Le Roux

You can take a LOT of ofbiz code out, but not the framework.

I wrote an ofbiz based application and reduced the footprint by 2 thirds.
But, I had to take bits and pieces out of the applications to use in my new
application.

Took about a month as I recall.

Would be nice to have each of the applications completely independant, i.e.
just delete them and all the rest work.

I don't think so, it depends really on OFBiz framework and applications

RE: ofbiz on mobile & embedded devices

In reply to this post by Jacques Le Roux

Also, no matter what you do with ofbiz, you need a connection to a database.
It that database lies on the mobile device, it needs to be synced with your
backend which is unreliable at best. Also, the database will get large over
time and probably will not fit to begin with.

If the database lies on a server some place, that implies a connection to
it. If the connection exists, better to write a small fast application that
makes JSON calls to a specialized application on the backend Ofbiz server.

Just my two cents.

I think you should go this way. Using OFBiz POS embedded in a mobile seems
impossible nowadays.
You may reuse some part of the POS code, not sure...

Also the hhfacility is a simple webapp, so not what you are looking for.

RE: ofbiz on mobile & embedded devices

In reply to this post by Erwan de FERRIERES

You dont have to "write it from scratch", only the UI which is fairly
simple.

I wrote a POJ (Plain old Java) POS application some years ago that ran on a
desktop without a browser. It had three possible interfaces to the
database. The first one where a copy of the db ran on the desktop machine
and was syc'd with the main server twice a day. The second made a db
connection to the same db server. That worked well, but there were some
concurrency issues. The last used JSON calls to the backend server. All
problems solved and the performance was not at all bad.

Hi Tony,

hhfacility is more a specific webapp for the hand-helds, with a
decorator designed for small screens.
Once again, we are on a web application, not a native one. OFBiz has not

Except the POS, which has a synchronization function.

If you want to make it work as a native app, then you'll have to write

well that sounds interesting, Skip!! initially I tried to do it but
didn't have that kind of patience and gave up on 3rd day :)

it will be great if you can share specifics on reducing size, if you
have documented it. because hit-n-trial approach will definitely more
than month for me.
