I want to deploy my application in Tomcat, where no UserTransaction is available in JNDI? I encountered some problem in the class org.jboss.seam.transaction.Transaction, which always exists the method getUserTransaction with a runtime exception: I am forced to disable the seam tx management in components.xml with <core:init debug="true" transaction-management-enabled="false"/> to get rid of the problem. But I think I am then only relying on the spring tx management and might get LazyInitilizationException. Is my understanding right? So first of all in 2.0.0 CR1 you will be able to use a spring TM as a Seam TM and will be able to enable "transaction-management-enabled". For now though who is doing the transaction management has nothing to do with getting LazyInitializationExceptions. What "transaction-management-enabled" disabled will mean is that when you wish to flush() your conversation scoped PC it will be best to do it inside of a Service call with @Transactional. Otherwise your configuration looks fine otherwise. A couple of points: 1. You don't need to inject a dataSource into your JpaTransactionManager. I'm not sure if it will mess things up or not but I know it is not necessary. 2. Make sure your components.xml has your entityManager definition: | <persistence:managed-persistence-context name="entityManager" | auto-create="true" | entity-manager-factory="#{entityManagerFactory}"/> And uncomment and rename your SeamManagedEntityManagerFactoryBean to something like: | <bean id="seamEntityManagerFactory" | class="org.jboss.seam.ioc.spring.SeamManagedEntityManagerFactoryBean"> | <property name="persistenceContextName" value="entityManager" /> | </bean> And make sure that you use your seamEntityManagerFactory with your JpaTransactionManager like: | <bean id="transactionManager" | class="org.springframework.orm.jpa.JpaTransactionManager"> | <property name="entityManagerFactory" | ref="seamEntityManagerFactory" /> | </bean> | Otherwise read over more closely the Seam+Spring docs regarding Persistence contexts.
