[jboss-user] [JBoss jBPM] - Spring integration: No platformTransaction manager defined e

[abecevello]

I'm trying to integrate jBPM into an existing Spring web application, however I have been unsuccessful in running a workflow with the Spring integrations.

Environment: Tomcat 6, Spring 2.5, jBPM 4.0, Hibernate 3.2.6.GA, Oracle 10g, running on Java 1.6 with Eclipse 3.4 (MyEclipse 7.5).

I have tried to configure jBPM with Spring according to the instructions in the developer guide (http://docs.jboss.com/jbpm/v4.0/devguide/html_single/#springIntegration), but so far it hasn't worked.

Tomcat will start successfully and the application can be used until any workflows are executed.  Then I get the error:

  |  org.jbpm.api.JbpmException: No platformTransaction manager defined.
  | 	at org.jbpm.pvm.internal.tx.SpringTransactionInterceptor.execute(SpringTransactionInterceptor.java:60)
  | 	at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:54)
  | 	at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:55)
  | 	at org.jbpm.pvm.internal.repository.DeploymentImpl.deploy(DeploymentImpl.java:89)
  |         at com.apption.jbpm.JBPMHelloWorld.doStuff(JBPMHelloWorld.java:56)

my.jbpm.cfg.xml (located on classpath):

  | <?xml version="1.0" encoding="UTF-8"?>
  | <jbpm-configuration>
  | 	<process-engine-context>
  | 		<repository-service />
  | 		<repository-cache />
  | 		<execution-service />
  | 		<history-service />
  | 		<management-service />
  | 		<identity-service />
  | 		<task-service />
  | 		<job-executor />
  | 		
  | 		<script-manager default-expression-language="juel"
  | 			default-script-language="juel"
  | 			read-contexts="execution, environment, process-engine, spring"
  | 			write-context="">
  | 			<script-language name="juel"
  | 				factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />
  | 		</script-manager>
  | 		
  | 		<command-service>
  | 			<retry-interceptor />
  | 			<environment-interceptor />
  | 			<spring-transaction-interceptor />
  | 		</command-service>
  | 	</process-engine-context>
  | 
  | 	<transaction-context>
  | 		<repository-session />
  | 		<db-session />
  | 		<message-session />
  | 		<timer-session />
  | 		<history-session />
  | 		<transaction />
  | 		<hibernate-session current="true" />
  | 	</transaction-context>
  | </jbpm-configuration>
  | 

Relevant spring application context:

  | <bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration">
  | 		<constructor-arg value="my.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" />
  | 

I can't figure out why this error is happening.  I have an appropriate Spring sessionFactory defined in Spring, as well as the usual Spring hibernateTemplate and HibernateTransactionManager:

  | <tx:annotation-driven transaction-manager="txManager" />
  | 
  | <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
  | 		<property name="sessionFactory" ref="sessionFactory"/>
  | 		<property name="jdbcExceptionTranslator" ref="jdbcExceptionTranslator"/>
  | 	</bean>
  | 
  | 	<bean id="txManager"
  | 		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
  | 		<property name="sessionFactory" ref="sessionFactory" />
  | 		<property name="prepareConnection">
  | 			<value>false</value>
  | 		</property>
  | 	</bean>
  | 

Does anyone know why this error is happening and how to fix it?
Thanks!
