Problem about transaction of mdb

Question

I've made a MDB,it works fine in WLS7.0, but when I upgraded the server from WLS7.0 to WLS8.1, I found this error:
          java.sql.SQLException: Cannot call Connection.rollback in distributed transaction. Transaction Manager will commit the resource manager when the distributed transaction is committed.
          at weblogic.jdbc.wrapper.JTSConnection.rollback()V(JTSConnection.java:570)
          at com.aspire.syn.delivery.ReceiverMDBean.onMessage(Ljavax.jms.Message;)V(ReceiverMDBean.java:320)

          at java.lang.Thread.startThreadFromVM(Ljava.lang.Thread;)V(Unknown Source)
          connection.close() exception:Cannot call Connection.rollback in distributed transaction. Transaction Manager will commit the resource manager when the distributed transaction is committed.
          JMS Connection Factories is "XA Connection Factory Enabled" , and I used a oracle jdbc datasource
          The mdb code as below:
          public void onMessage(Message msg){       
          java.sql.Connection conn = null;
          ...get the connection
          try{
          conn.setAutoCommit(false);
          ...business flow
          conn.commit();
          conn.close();
          } catch(JMSException jmse){
          try{
          conn.rollback();
          } catch(SQLException ee){}
          messageDrivenContext.setRollbackOnly();
          } catch(Exception e){
          try{
          conn.rollback();
          } catch(SQLException ee){}
          e.printStackTrace();
          messageDrivenContext.setRollbackOnly();
          I have specified the attributes in ejb-jar.xml as per weblogic documentation as below:
          <ejb-jar>
          <enterprise-beans>
          <message-driven>
          <description>Message driven Bean to receive Siebel messages</description>
          <ejb-name>ReceiverMDBean</ejb-name>
          <ejb-class>cignex.jms.ReceiverMDBean</ejb-class>
          <transaction-type>Container</transaction-type>
          <message-driven-destination>
          <destination-type>javax.jms.Queue</destination-type>
          </message-driven-destination>
          </message-driven>
          </enterprise-beans>
          <assembly-descriptor>
          <container-transaction>
          <method>
          <ejb-name>ReceiverMDBean</ejb-name>
          <method-name>*</method-name>
          </method>
          <trans-attribute>Required</trans-attribute>
          </container-transaction>
          </assembly-descriptor>
          </ejb-jar>
          Can someone help me with this.
          Thanks!

Thanks for ur help!
          WLS 8.1
          <JDBCTxDataSource EnableTwoPhaseCommit="true"
          JNDIName="JDBCDataSource" Name="JDBCDataSource"
          PoolName="JDBCConnectionPool" Targets="myserver"/>
          WLS 7.0
          <JDBCDataSource JNDIName="JDBCDataSource" Name="JDBCDataSource" PoolName="JDBCConnectionPool"/>
          Because JDBCDataSource is the default datasource when you create a new datasource in WLS7.0, JDBCTXDataSource is the default datasource in WLS8.1.
          After I changed the config.xml, it's ok!
