[jboss-user] [jBPM Users] - jbpm 4.2 spring 2.5.6 integration

[iga3k]

Hello,

I've been looking around for a good open source bpm solution and I end up choosing jBPM. Now, I'm trying to integrate it with Spring, but I'm facing some troubles. 

Here is the jbpm minimal configuration that I'm trying to use:


  | 	<process-engine-context>
  | 		<command-service>
  | 			<retry-interceptor />
  | 			<environment-interceptor />
  | 			<spring-transaction-interceptor />
  | 		</command-service>
  | 	</process-engine-context>
  | 
  | 	<transaction-context>
  | 		<transaction />
  | 		<hibernate-session current="true" />
  | 	</transaction-context>
  | 

, the spring configuration: 


  | 	<bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration">
  | 		<constructor-arg value="com/psinova/jbpm.cfg.xml" />
  | 	</bean>
  | 
  | 	<bean id="processEngine" factory-bean="jbpmConfiguration" factory-method="buildProcessEngine" />
  | 	<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
  | 	<bean id="executionService" factory-bean="processEngine" factory-method="getExecutionService" />
  | 

and when spring is trying to initialize the first bean, a npe is thrown with this stack:


  | Caused by: java.lang.NullPointerException
  | 	at org.jbpm.pvm.internal.cfg.ProcessEngineImpl.checkDb(ProcessEngineImpl.java:177)
  | 	at org.jbpm.pvm.internal.cfg.ProcessEngineImpl.buildProcessEngine(ProcessEngineImpl.java:170)
  | 	at org.jbpm.pvm.internal.cfg.SpringConfiguration.buildProcessEngine(SpringConfiguration.java:81)
  | 	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

  | 	at java.lang.reflect.Method.invoke(Method.java:597)
  | 	at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:115)
  | 

I've also created a JIRA ticket for this issue: https://jira.jboss.org/jira/browse/JBPM-2646
Am I doing something wrong? Please advise!

Kind regards,
Alexandru.
