call JBPM process from seam project

zhouraymond Aug 22, 2012 2:22 PM

Hello

I created two projects in Jboss Developer Studio 5, one is seam project and one is jbmp project(BPMN2.0), I am trying to start the sample process(sample.bpmn - in my jBPM project) from a seam action by calling the generated class ProcessMain(this ProcessMain can be run separately in JDS5)

when I ran this from JDS5, I am getting the error

======

Unable to instantiate 'org.drools.bpmn2.BPMN2ProcessProviderImpl'

Caused by: java.lang.ClassNotFoundException: org.drools.bpmn2.BPMN2ProcessProviderImpl from BaseClassLoader@e873b{vfsfile:/C:/Dev/EnterprisePlatform-5.1.1/jboss-eap-5.1/jboss-as/server/default/deploy/myApp.war/}

I am using Jboss EAP5.1.1 as my JDS5 server runtime. and I have added all the jar from my jbdevstudio5\runtimes folder into my seam project, but still getting this error, could anyone here give me some direction on how to implement this?

thanks a lot

P.s I attached a screen shot to show my jds5 projects structure.

it's definitely something wrong with you class path settings, make sure you have all the jbpm and drools (including all their dependencies) deployed into your server.

Thanks for your reply, I downloaded the drools-bpmn2-5.1.1.jar and added into the class path, then everything works, I just wonder why this jar is not included in the distribition if it is required?

or when I played these two from Jboss developer environment, this one got executed as drools-bpmn, not a jbpm bpmn?

thanks

Hi,

In jBPM 5.3.0, you need 'org.jbpm.bpmn2.BPMN2ProcessProviderImpl', not 'org.drools.bpmn2.BPMN2ProcessProviderImpl'. I guess the error was caused by old drool-compiler jar in your classpath. So the solution would not be adding drools-bpmn2-5.1.1.jar but making sure you use the latest jars from jbpm-5.3.0.Final-bin.zip.
