HIbernate 4.2 PuId没有活动事务

我有使用JPA(Hibernate 4.2)的Web应用程序,JavaEE 7在WebSphere 8.5上运行。我想避免在我的应用程序中使用EJB。当我试图坚持更改时,我得到javax.persistence.TransactionRequiredException:没有PuId的活动事务。我希望websphere能够管理交易。在wildfly 8.0上一切正常。

我的persistence.xml

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence version="2.0"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                                 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xmlns="http://java.sun.com/xml/ns/persistence">

    <persistence-unit name="org.jbpm.domain" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>jdbc/MyApp</jta-data-source>
       <class>Diagram</class>

        <exclude-unlisted-classes>true</exclude-unlisted-classes>

        <properties>
            <property name="hibernate.max_fetch_depth" value="3"/>
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform" />
            <property name="hibernate.id.new_generator_mappings" value="false"/>
        </properties>
    </persistence-unit>

class 我试图坚持改变:

    import javax.inject.Inject;
    import javax.inject.Named;
    import javax.transaction.Transactional;

    @Transactional
    @Named
    class PersistentAssetStorage {
      @Inject
        private EntityManager em;

         public long saveProcessDefinition(final Diagram diagram) {
         em.persist(diagram);
    }
}

遗憾的是,WebSphere 8.5.5仅符合Java EE 6(尚未7),因此它不了解@Transactional。对于WebSphere 8.5.5,您必须将其包装在无状态EJB中。添加@Stateless代替@Transactional,它应该有效。 WebSphere支持Web模块中的EJB,因此您不必创建单独的EJB模块。
