http://community.jboss.org/message/523318#523318 Author : Flavio Donzé Profile : http://community.jboss.org/people/flavio.donze Message: -------------------------------------------------------------- Hello I'm having the same problems as Christian stated. We are using JPA transations which worked in version 4.1 and I can't get it running in 4.3 because of the mentioned NPE. We also have an EntityManager and using the following configurations we provided the connection and transations manager to jBPM: *jbpm.hibernate.cfg.xml* <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-configuration PUBLIC -//Hibernate/Hibernate Configuration DTD 3.0//EN http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd> <hibernate-configuration> <session-factory> <property name="hibernate.dialect">${hibernate.dialect}</property> <property name="hibernate.hbm2ddl.auto">update</property> <property name="hibernate.jdbc.batch_size">2000</property> <property name="javax.persistence.transactionType">JTA</property> <property name="hibernate.transaction.manager_lookup_class">com.softmodeler.server.persistence.SoftmodelerTransactionManagerLookup</property> <property name="hibernate.connection.provider_class">com.softmodeler.server.persistence.SoftmodelerConnectionProvider</property> <mapping resource="jbpm.repository.hbm.xml" /> <mapping resource="jbpm.execution.hbm.xml" /> <mapping resource="jbpm.history.hbm.xml" /> <mapping resource="jbpm.task.hbm.xml" /> <mapping resource="jbpm.identity.hbm.xml" /> </session-factory> </hibernate-configuration> Notice the "hibernate.transaction.manager_lookup_class" and the "hibernate.connection.provider_class" properties. The Spring configuration looked like this, no sessionFactory bean is defined: <osgi:reference id="transactionManager" interface="org.jencks.GeronimoPlatformTransactionManager"/> <bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration"> <constructor-arg value="jbpm.cfg.xml"/> </bean> <bean id="jbpmProcessEngine" factory-bean="jbpmConfiguration" factory-method="buildProcessEngine"/> <bean id="jbpmRepositoryService" factory-bean="jbpmProcessEngine" factory-method="getRepositoryService" /> <bean id="jbpmExecutionService" factory-bean="jbpmProcessEngine" factory-method="getExecutionService" /> <bean id="jbpmTaskService" factory-bean="jbpmProcessEngine" factory-method="getTaskService" /> I tried to hack around the code to get it working, made my own SpringProcessEngine without using LocalSessionFactoryBean. public static ProcessEngine create(ConfigurationImpl configuration) { MySpringProcessEngine springProcessEngine = null; ApplicationContext applicationContext = null; applicationContext = (ApplicationContext) configuration.getApplicationContext(); springProcessEngine = new MySpringProcessEngine(); springProcessEngine.applicationContext = applicationContext; springProcessEngine.initializeProcessEngine(configuration); // do not create session, hibernate configuration is set in jbpm.cfg.xml springProcessEngine.checkDb(configuration); return springProcessEngine; } Well now I'm getting a different NPE, jBPM is trying to access org.springframework.transaction.PlatformTransactionManager, but I'm using org.apache.geronimo.transaction.manager.GeronimoTransactionManager. What would be the correct way to hock in my TransationManager? greets and thanks -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523318#523318
