[jboss-user] [JBoss Seam] - Seam 2.0 NOT support OpenJPA?

[davidclf]

I try to test the Seam's compatibility with openjpa.
The web project is tomacat + myfaces + seam +  spring jpa + openjpa.
I define entityManagerFactory in the application.xml

  | <!-- JPA EntityManagerFactory -->
  | 	<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
  | 		<property name="dataSource" ref="dataSource"/>
  | 		<property name="loadTimeWeaver">
  | 			<bean class="org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver"/>
  | 	  </property>
  | 		<property name="jpaVendorAdapter">
  | 			<!--
  | 			<bean class="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter">
  | 				<property name="databasePlatform"
  | 						value="org.springframework.samples.petclinic.toplink.EssentialsHSQLPlatformWithNativeSequence"/>
  | 				<property name="showSql" value="true"/>
  | 			</bean>
  | 			-->
  | 			<!--
  | 			<bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
  | 				<property name="database" value="HSQL"/>
  | 				<property name="showSql" value="true"/>
  | 			</bean>
  | 			-->
  | 			<bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter">
  | 				<property name="database" value="HSQL"/>
  | 				<property name="showSql" value="true"/>
  | 			</bean>
  | 		</property>
  | 	</bean>
  | 
And Define managed-persistence-context in component.xml

  | <persistence:managed-persistence-context name="courseEntityManager"
  | 	entity-manager-factory="#{entityManagerFactory}"
  | 			auto-create="true" />
  | 
The Web Project reports Error

  | 2007-09-21 09:21:09,981 ERROR [org.jboss.seam.jsf.SeamPhaseListener] - <uncaught exception>
  | java.lang.RuntimeException: could not proxy delegate
  | 	at org.jboss.seam.persistence.HibernatePersistenceProvider.proxyDelegate(HibernatePersistenceProvider.java:102)
  | Caused by: java.lang.ClassCastException: org.apache.openjpa.persistence.EntityManagerImpl
  | 	at org.jboss.seam.persistence.HibernatePersistenceProvider.proxyDelegate(HibernatePersistenceProvider.java:98)
  | 
Is it Means that Seam 2.0 Not Support OpenJPA? or Am I Wrong?
AnyOne Can Help? Thank in Advance!
