这需要花费很多时间才能解决。我有一个portlet应用程序是8.0，并使用hibernate进行数据库事务。我正在尝试将其迁移到8.5.5自由配置文件。我们正在使用hibernate 3.6.9。
persistance.xml如下所示：
<property name="jpaProperties">
<value>
hibernate.transaction.manager_lookup_class=org.hibernate.transaction.WebSphereTransactionManagerLookup
hibernate.current_session_context_class=jta
hibernate.transaction.flush_before_completion=true
hibernate.connection.release_mode=auto
</value>
</property>
记录：
