how to invoke Java class

ace_team Jul 21, 2011 11:50 AM

Hi all,

I'm newbie in jBPM5 and sometime I've very trivial problems. I would like to connect my workflow with a remote WS. I've the WSDL and I tryed to create a WS-client with axis2 (out of jBPM tool). Now I would like to implement a Service Task that uses this client...

So, how can I invoke a Java class within jBPM workflow?? Which steps do I have to follow?

Could someone help me?!!

Thanks

Carlo

Probably easiest way would be to create a custom workitem that calls your class and does what you need it to do. Docs have a good section on domain specific activities.

Probably you're right. Reading the documentation I had the same idea. But my question is: how can I exactly use a workitem to call a Java method? Seeing "Hello Worlds" example, I think I just have to put the method's signature, but it doesn't work. I can't find a step by step guide...

Look at chapter 13 of the docs - http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html. Specifically 13.2.4 Executing Service Nodes.
Also looking at the workitem handler example in 13.2.4 when your process reaches the workitem node, the handler's executeWorkItem method gets called. This is all java code, so as long as you have your specific classes you want to call methods upon on the classpath, you can do whatever you want.

Thanks! I'm working with jBPM5.0 than I had not read the jBPM5.1 documentation, yet!
