I am sorry  ofbiz BigFish

BigFish.

Jean-Luc is having issues setting up OFBiz with ESB. Not specific to
BigFish but he is interested in using it.

Hi Jean-Luc,

we have some experience with OFBiz connected to Apache Camel with Apache
ServiceMix for integration.
We use REST endpoints and JMS/ActiveMQ to connect OFBiz to the ESB. For
JMS we have modified the JMS/Service functionality in OFBiz.

Regards,

Michael

Hi Jean-Luc,

thank you for mails. I'm currently in a project and have no time to answer your questions immediately, sorry.

I will try to write the main aspects down over the weekend and hope this will help you.

For further discussion, please use the original mailing list so  we can share with the community.

Thanks and regards,

Michael

Good morning Michael

This is Jean-Luc you have answered in the ofbiz forum.

I am trying to to precisely what you have mentioned but I am using jboss Fuse esb and ServiceWorks.

But I can not find any any doc in this area.

Is it possible that you help me with some documents ? some small example of:

 REST endpoints and JMS/ActiveMQ to connect OFBiz to the ESB. For JMS we have modified the JMS/Service functionality in OFBiz.

I will be very grateful so I can start.

kind regards

Good morning Michael

I supposed you have been busy during the weekend.

Hi Jean-Luc,

I will try to give you a brief overview about our OFBiz/ESB integrations.

We have different interfaces to/from OFBiz, depending on the steps which are needed to process the data between OFBiz and other systems.

We have interfaces through REST, FTP to the outside world with different data formats (XML, CSV, EDI). These formats are transformed to a main "house format" and transported to OFBiz.

The REST endpoints are provided by the ESB (camel-jetty), not OFBiz directly. This is to decouple the systems in case the server setting will be more decentralized in the future.

For the REST endpoints we mainly have two "paths":
- directing the request directly to OFBiz with url rewriting in Apache (for data which comes in the "house format" and need no processing (request -> camel-jetty -> Apache -> OFBiz)
- directing the request and the data to an ActiveMQ endpoint for further processing (request -> camel-jms -> [different processing steps, enrichment, transformations etc.] -> camel-jms -> OFBiz)

For the FTP endpoints we have one main path (file -> camel-file -> camel-jms -> [different processing steps, enrichment, transformations etc.] -> camel-jms -> OFBiz)

The data path from OFBiz to other systems is through JMS (OFBiz jms-service -> camel-jms -> [further processing] -> [several endpoints]

The main paths contain several content based routers and different processors to enhance the data. I think this would blow this overview a little bit.

So OFBiz ist addressed in two ways: through normal https requests and through JMS. https should be clear.

For JMS, OFBiz already has a mechanism for sending and receiving JMS messages, used for the distributed cache clear.

Calling a service through JMS ist configured in the serviceengine.xml. The JMS message contains a service context map which is sent in the message body:

<!-- Config of output channel to send service calls via JMS -->
<jms-service name="outputChannel" send-mode="all">
   <server jndi-server-name="default" jndi-name="ConnectionFactory" topic-queue="ofbizServiceOutbound" type="queue" username="xxx" password="xxx" listen="false"/>
</jms-service>

The service to call another service through JMS (or just send some data to a queue) is configured as follows:

<!-- services.xml -->
<!-- Dummy service to demonstrate the way to call a service of the ESB component by sending a JMS message formed by this service definition -->
<service name="dummyCallEaiService" engine="jms" location="outputChannel" invoke="dummyService"> <description>Send a JMS message to an EAI queue to call an ESB service</description>
   <attribute name="parameter" type="String" mode="IN" optional="false" allow-html="any" /> </service>

The main elements are:

engine="jms":
defines the JMS service engine to call a service, a JMS message is generated instead of calling an OFBiz service
location="outputChannel":
specifies the queue to send the message to (configured above)
invoke="dummyService":
that's the name of the remote service to call (if any) or just some identifier for the message content to decide where to route the message or how to transform it

The way to call an OFBiz service through JMS is as follows

<!-- JMS Service Queue/Topic Configuration -->
<!-- Config of input channel to receive service calls via JMS -->
<jms-service name="inputChannel" send-mode="none">
   <server jndi-server-name="default" jndi-name="ConnectionFactory" topic-queue="ofbizServiceInbound" type="queue" username="xxx" password="xxx" listen="true"/>
</jms-service>

This is the configuration for the JMS provider at the ESB side.

The other JMS configurations take place in the jndi.properties

java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory java.naming.provider.url=tcp://127.0.0.1:61616
# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.ofbizServiceInbound = ofbizServiceInbound
queue.ofbizServiceOutbound = ofbizServiceOutbound

Now OFBiz listens to the configured queues.

To call an OFBiz service through JMS, we simply put a service context map in the body of the message and send it to the queue. We have a camel processor which takes the original data and wraps it in the service context map, specifying the OFBiz target service to call. No decision logic necessary at the OFBiz side.

Hope that helps to get things running on your side.

Michael

Thanks very much Michael
Yes this give me a clarification specially esb-ofbiz, ofbiz-esb was a mystery to me.
I think this is help to many other people
Tks

[Michael Brohl-3]

As an addition to my previous email and in reference to my statement "or
JMS we have modified the JMS/Service functionality in OFBiz.": it is not
necessary to modify OFBiz here, you can use OOTB OFBiz to get things
running.

We have just written a simplified service to get rid of OFBiz specific
code/service parameters such as userLogin, timezone etc. because they
are not needed for calls to non-OFBiz systems.

Michael
