Hi! I posted my previous message from the web client and it was corrupted. So here is the full one: get InvocationTargetException after the following: return constructor.newInstance( kbase, conf, env ); in KnowledgeStoreServiceImpl. I see that in return (T) constructorAccessor.newInstance(initargs) of Constructor class it throws the InvocationTargetException. The exception is null so I can't see what it the problem! I call the code from this: EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.drools.persistence.jpa"); Environment env = KnowledgeBaseFactory.newEnvironment(); env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf); env.set(EnvironmentName.GLOBALS, new MapGlobalResolver()); env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager()); ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env); I define the transaction manager in my spring beans like this: <!-- Bitronix Transaction Manager embedded configuration --> <bean id="xaDataSource" class="bitronix.tm.resource.jdbc.PoolingDataSource" init-method="init" destroy-method="close"> <property name="className" value="bitronix.tm.resource.jdbc.lrc.LrcXADataSource" /> <property name="uniqueName" value="java/DS1" /> <property name="maxPoolSize" value="5" /> <property name="minPoolSize" value="0" /> <property name="allowLocalTransactions" value="false" /> <property name="testQuery" value="SELECT 1 FROM DUAL" /> <property name="driverProperties"> <props> <prop key="user">username</prop> <prop key="password">username</prop> <prop key="url">url</prop> <prop key="driverClassName">oracle.jdbc.OracleDriver</prop> </props> </property> </bean> <bean id="btmConfig" factory-method="getConfiguration" class="bitronix.tm.TransactionManagerServices"> <property name="serverId" value="spring-btm" /> </bean> <bean id="bitronixTransactionManager" factory-method="getTransactionManager" class="bitronix.tm.TransactionManagerServices" depends-on="btmConfig,xaDataSource" destroy-method="shutdown" /> <bean id="jtaTransactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"> <property name="transactionManager" ref="bitronixTransactionManager" /> <property name="userTransaction" ref="bitronixTransactionManager" /> </bean> <!-- end of Bitronix Transaction Manager embedded configuration --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="OnMediaSessionFactory" /> </bean> I see that bitronix is up via the debugging messages. (2011-03-16 12:14:53,399 DEBUG ( PoolingDataSource.java:84) - building XA pool for java/DS1 with 0 connection(s) etc..) in persistence.xml I have: <persistence-unit name="org.drools.persistence.jpa" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java/DS1</jta-data-source> <mapping-file>persistenceorm.xml</mapping-file> <class>org.drools.persistence.info.SessionInfo</class> <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class> <class>org.drools.persistence.info.WorkItemInfo</class> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" /> <property name="hibernate.connection.autocommit" value="false" /> <property name="hibernate.max_fetch_depth" value="3" /> <property name="hibernate.show_sql" value="true" /> <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" /> <property name="hibernate.jndi.class" value="bitronix.tm.jndi.BitronixInitialContextFactory"/> <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup" /> </properties> </persistence-unit> What could cause the problem? When I defined the btm with tomcat and not with spring - it worked fine. (but I had context reloading problems). when I define it only with spring - it get this weird exception. Thanks!
