Seam-Spring integration transaction problems
Hi,
I´m currently developing an application using:
- Seam 2.2.0GA
- Spring 2.5.6
- Richfaces 3.3.2SR1
- Trinidad 1.2.12
- HibernateEntityManager 3.4.0GA
- Hibernate Core 3.3.2GA
Somehow Spring and Seam is not playing well together although we configured the integration exactly as described in Dan Allens article.
components.xml
<persistence:managed-persistence-context name="entityManager"
auto-create="true"
entity-manager-factory="#{entityManagerFactorySpring}"
scope="SESSION" />
<core:init jndiPattern="#{ejbName}/local" debug="true" transaction-management-enabled="true"/>
<spring:context-loader />
<component name="threadPoolDispatcher" class="org.jboss.seam.async.ThreadPoolDispatcher" />
<!-- Install the SpringDispatcher as default -->
<spring:spring-task-executor-dispatcher schedule-dispatcher="#{threadPoolDispatcher}" task-executor="#{springThreadPoolTaskExecutor}"/>
<spring:spring-transaction platform-transaction-manager="#{transactionManager}" join-transaction="true" />applications-context.xml
<bean id="entityManagerFactorySpring" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="persistenceUnitName" value="easyClubDatabasePU"/> <!-- Use alternate location to prevent JBoss AS from automatically loading persistence units (in-container) --> <property name="persistenceXmlLocation" value="classpath:META-INF/persistence-spring.xml"/> <property name="jpaDialect"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect"/> </property> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" > <property name="showSql" value="false"/> <property name="generateDdl" value="true"/> </bean> </property> </bean> <!-- This example uses resource local JpaTransactionManager. You could just as easily use a JtaTransactionManager --> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <!-- Be sure to specify the SeamManagedEntityManagerFactory since that will manage the EM that will be beginning and ending transactions.--> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <tx:annotation-driven proxy-target-class="true" /> <seam:configure-scopes default-auto-create="true" /> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"> <!-- Because we have multiple EntityManagerFactories in this applicaitonContext identify the SeamManagedEntityManagerFactory as the default --> <property name="defaultPersistenceUnitName" value="easyClubDatabasePU:extended"/> </bean> <!-- EMF that wraps a Seam Managed EM instance for use in Spring --> <bean id="entityManagerFactory" class="org.jboss.seam.ioc.spring.SeamManagedEntityManagerFactoryBean"> <!-- The Seam managed-persistence-context component name. --> <property name="persistenceContextName" value="entityManager" /> <!-- Optionally provide a unit name. If not specified the default would be the persistenceContextName --> <property name="persistenceUnitName" value="easyClubDatabasePU:extended"/> </bean>
When debbugging into the transactions, the Spring TX begins and commits every request. So does the Seam-TX. But some exceptions occur when Seam tries to open it´s transaction:

No it´s hard to understand why these exception occures as there are not many reported errors with this Seam/Spring configuration. Are there any misconfigurations or things I forgot in my configuration or what could be the reason for this?
Anyone with some help regarding this topic?
