So long as you don't need an RFH2 with JMS properties, just set the message format in the MQMD to MQFMT_NONE.
Most JMS applications are tolerant of messages without RFH2.

If I want to receive the JMS message (like TextMessage, BytesMessage and MapMessage) from C, is the only way to parse the received string myself?
eg: for MapMessage, I'll receive a xml string from C, then parse the xml myself.
Is there any other better way? |

Read up in the using Java manual  where the mapping of base MQ to JMS MQ is described.
To get a TextMessage just set the format to MQFMT_STRING.
Enjoy

I use the JMS to send the TextMessage, but received below from C:
RFH ? 3MQSTR ¸ <mcd><Msd>jms_text</Msd></mcd> L<jms><Dst>queue:///PTEST.Q1</Dst><Tms>1223452199596</Tms><Dlv>2</Dlv></jms> test TextMessage |

What you have is an RFH header. Set your JNDI to target client MQ or your uri as "queue://QMGR/QUEUE?targetClient=1". This will suppress the RFH header.
Note: you could also use the XMS support pack which gives you a JMS like interface in non java languages.
Enjoy

I couldn't change the target client option. I want to code a MQ utility tool using C, to browse/receive the message from queue.
But the queue maybe only used for Java application, don't need to change the target client option.
Not formiliar with XMS, could it receive the JMS message directly?
The bad way is to parse the received message myself. |

XMS will behave like JMS for you. Read up on the support pack documentation. Search the support pack with message service.
