Tomcat上开发基于Struts2+jotm2.1+hibernate3项目时出现的JTA事务问题，大家帮帮忙

不想使用spring,但又要考虑事务，所以换成了jotm。
JTA配置其实是没问题的，问题就出在我想使用SessionFactory.getCurrentSession()，而不想用SessionFactory.openSession()。
理由很简单，因为很多人老是open之后就就忘了关，所以想干脆交给容器的jta去管。

数据源配置为context.xml

	<Resource   

			auth="Container"   

			type="javax.sql.DataSource"   

			name="jdbc/mysql"  

			username="root"   

			password="lnie"   

			maxActive="4"   

			maxIdle="2"   

			maxWait="5000"   

			driverClassName="com.mysql.jdbc.Driver"   

			url="jdbc:mysql://localhost:3306/test?autoReconnect=true"   

			/>

	  <Resource name="UserTransaction" auth="Container"  

			type="javax.transaction.UserTransaction"  

			factory = "org.objectweb.jotm.UserTransactionFactory"  

			jotm.timeout = "60"/>

web.xml配置为

	<resource-ref>

		<description>DB Connection</description>

		<res-ref-name>jdbc/mysql</res-ref-name>

		<res-type>javax.sql.DataSource</res-type>

		<res-auth>Container</res-auth>

	</resource-ref>



	<resource-ref>  

        <description>UserTransaction description</description>  

        <res-ref-name>UserTransaction</res-ref-name>  

        <res-type>javax.transaction.UserTransaction</res-type>  

        <res-auth>Container</res-auth>  

    </resource-ref>

hibernate配置为



		<property name="hibernate.bytecode.use_reflection_optimizer">false</property>

		<property name="connection.datasource">java:comp/env/jdbc/mysql</property>

		<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

                <!--后面测试发现下面这行配置不起作用，不知道为什么，很困惑-->

		<property name="current_session_context_class">jta</property>



		<property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>

		<property name="jta.UserTransaction">java:comp/env/UserTransaction</property>

		<property name="transaction.manager_lookup_class">org.hibernate.transaction.JOTMTransactionManagerLookup</property>

调用的Java代码：



UserTransaction tx = getUserTransaction();

			System.out.println(tx);

Session session = sessionfactory.getCurrentSession();//这行报异常

异常信息
