Hi guys, I'm trying to deploy a spring based Knowledege Session with JPA persistence on Jboss 5.1, I was able to do it using a RESOURCE_LOCAL persistence unit but I would like to use a container JTA based deployment. Basically, JPAConfiguration requires a Spring PlatformTransactionManager then I tried to use the following combination: <bean id="springTxManager" class="org.springframework.transaction.jta.JtaTransactionManager" /> <jee:jndi-lookup id="springEMF" jndi-name="java:DroolsEMF"/> The problem is that using it, SingleSessionCommandService.initTransactionManager does not create a JPAManager. So, my guess for this to work is to add support for this on SingleSessionCommandService or change JPAConfiguration (drools-spring-1.0.0.xsd) to accept that no transaction-manager is defined, causing Drools JtaTransactionManager to lookup the TransactionMananger from JNDI context. The only way that I could deploy it is using these beans definitions: <bean id="springEMF" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceXmlLocation" value="classpath:META-INF/spring-persistence.xml" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" /> </property> </bean> <bean id="springTxManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="springEMF" /> </bean> Thanks. -- Best regards, Cristiano Nicolai
