    Spring integration: No platformTransaction manager defined e

    abecevello Jul 21, 2009 2:11 PM

      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>

 <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!
