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!
