I'm trying to read a message from a MQ queue using JMS. The program for doing this is quite simple and therefore I havn't posted it (it's pratically straight out of the 'Using Java' guide).
All is apparently working OK - I can read the message as a TestMessage and view the contents as well as the RFH2 header. But only if the RFH2 header is simple - like "<A>valA</A><B>valB</B>"
Once I start using a more complex header - lige <aList><A>val_1</A><A>val_2</A></aList> the receive method fails with the following exception:
An JMSException ocurred: MQJMS1050: The MQRFH2 header has an incorrect format, linkedException=javax.jms.MessageFormatException: MQJMS1050: The MQRFH2 header has an incorrect format
javax.jms.MessageFormatException: MQJMS1050: The MQRFH2 header has an incorrect format
at com.ibm.jms.JMSMessage.newMessageFormatException(JMSMessage.java:5011)
at com.ibm.jms.JMSMessage._parseUsrFolder(JMSMessage.java:3498)
at com.ibm.mq.jms.MQJMSMessage.createJMSMessage(MQJMSMessage.java:507)
at com.ibm.mq.jms.MQMessageConsumer.getMessageQ(MQMessageConsumer.java:1740)
at com.ibm.mq.jms.MQMessageConsumer.getMessage(MQMessageConsumer.java:4313)
at com.ibm.mq.jms.MQMessageConsumer.receiveInternalQ(MQMessageConsumer.java:2407)
at com.ibm.mq.jms.MQMessageConsumer.receiveNoWaitQ(MQMessageConsumer.java:2203)
at com.ibm.mq.jms.MQMessageConsumer.receiveNoWait(MQMessageConsumer.java:4274)
at MessageSender.run(MessageSender.java:53)
at MessageSender.main(MessageSender.java:103)
But surely there is nothing wrong with the RFH2 header - it is displayed correctly in the message when reading through rfhutil and I can read and manipulate it in WBIMB. So what's going on here - can I really be the first person to use a list in the RFH2 header of a text message (surely not).

Your RFH2 was not formed with JMS. There is no nesting allowed.
so
| Quote: |
| <aList><A>val_1</A><A>val_2</A></aList> |
is illegal
Read the documentation !! Using java ..
Enjoy  |
