Regarding wrapper for listing/getting the data

[Rahul Utkoor]

Hello all,

We are having a requirement of writing a wrapper for listing/getting the
data for the functionalities in accounting module of Ofbiz. For some of the
listing functionalities, Ofbiz UI is tightly coupled with the backend
implementation. In a crude way we can rewrite all the functionalities using
entityquery method, but it involves lot of effort to redo it for all of
them. Is there any optimal way to make use of existing methods?
Any suggestions are most welcome.

*Thanks & Regards,*
*Rahul.*

Hi Rahul

Do you have an external system that wants to talk to OFBiz and thus require
an interface/wrapper/web service to extract data from OFBiz?

Hi Girish,

Thanks for the reply.
Yes, In our case an external system wants to interact with Ofbiz and get
information.

That would suggest a rest

Hi smits,

We are able to write the rest api's for the services(for adding/updating
the data) provided by ofbiz. Right now we are facing the difficulty with
non-service functionalities(mostly for listing and getting the data).

Hi Rahul,

I would say that many of our (potential) adopters and contributors would
interested to learn how you have achieved the implementations of the REST
functionalities on services.

Can you explain your approach a bit more?

Maybe, when explaining a bit more, this will trigger other contributors to
share their insights/approached to help you move forward. While at the same
time, have the community come up with an acceptable approach to have such
in play in the code base.

Hello Smits,

I apologise for the late reply, I was busy with my exams and projects.

*Our Approach :*
We referred to the Services list provided by ofbiz and generated a template
API wrapper for the services. This wrapper is working for Post calls. We
are currently working on the REST APIs and our ultimate goal is to
contribute back to the Community.

*Project Git link* :
https://github.com/sbv-solutions-private-limited/ofbiz-framework

You may find the wrappers written in the below link,
https://github.com/sbv-solutions-private-limited/ofbiz-framework/blob/trunk/hot-deploy/rest/src/main/java/org/cfbiz/rest/custom/PingResource.java

Please feel free to ask questions/queries related to our approach.

Hi Rahul,

Are you aware of the effort at https://issues.apache.org/jira/browse/OFBIZ-4274 ?

Thanks

[Rahul Utkoor]

Hello Jacques,

Thanks for pointing to that issue. I had gone through the responses and
understood few of the trials made. However, I have couple of questions:


   1.

   In some of the mid comments people are talking about writing a wrapper
   for OFBIZ services, why can’t we use it directly and extend it which is
   considered to be less effort than writing everything from
   scratch?(Temporary solution for the current developers)
   2.

   Since the work is still in progress, if someone wants to build REST APIs
   for non-services, then what could be best way to achieve it?(As far as I
   see converting non-services functionalities to services seems to be the
   only possible solution, please correct me if i am wrong)


Similar to the approach as mentioned by Adrian
<https://issues.apache.org/jira/browse/OFBIZ-4274?focusedCommentId=13031517&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13031517>
, we followed the below approach to write wrappers to the services.

   -

   We collected all the services and its respective parameters/attributes
   and generated the api structure for each and every service
   -

   We are able to smoothly use the REST APIs for the services (no
   authentication integration yet)


We are facing the below issues while trying to create REST Wrappers for the
non-services,

   -

   Suppose, if we want to create a wrapper for finding a party / listing
   parties from Party module, then we don’t have a proper service that
   satisfies the requirement
   -

   Currently we followed a crude approach by writing a service for it(which
   is not working properly, facing some parameter matching issues, since it
   involves internal calls to multiple entities)


We felt the above approach to be apt. Welcome feedback and comments on the
approach.

Is it possible to automate for writing the wrappers to OFBIZ non-services?

A small correction,
"Suppose, if we want to create a wrapper for *finding a party / listing
parties from Party module,* then we don’t have a proper service that
satisfies the requirement"
The example which I was referring is finding invoice / listing invoice from
Accounting module.

Hi Rahul,

I guess the main reason why we need to wrap OFBiz services (especially this
that involve creating & updating entity records) is that many of the OFBiz
services execute other services through the ECA/SECA principle. If we were
to have simple REST crud services (in essence meaning executing SQL
statements against the tables in the underlying RDBMS), that would mean
that no OFBiz service would be invoked and subsequently the nested services
(through ECAs/SECAs) would not be executed.

Best regards,

Pierre Smits

Thanks Pierre,

We indeed use an EDA architecture and it's fundamental in OFBiz.

Another reason is we want to be able to generate REST services using the same mechanism than for RMI, XML-RPC and SOAP, ie using the export attribute.
The advantage is you then keep using the service engine.

I fear getting out of that way will cross multiple issues, as you mentioned for instance...
