Hi MQ masters,
I am using a (MQ Program) Java program written in Native MQ Java bindings and writing a customised serializeable MQ Object and putting it into the queue. A JMS program retrieving from the queue retrieve the message as a JMSBytesMessage.
How can the JMS program reserialise the bytemessage into the original MQ Object ?
Should the setting and changes be done on the MQ Program or in the JMS program ?
Can I change any setting in the MQ program so that the JMS can receive the MQ message as a Object Message ?
Cheers |

Hi MQ experts,
any way to deserialise the object ?
Is there any setting I can set in the native Java MQ API so the JMS could serialise the message as a ObjectMessage ?
Thanks. |

Hi friends,
more elaboration about more scenario :
I am using native MQ java to write a customised object 'MQContainer' into the MQ queue. When JMS prog picks up the message, it picks it up as a JMSBytesMessage and could not serialise the message into 'MQContainer'.
What should It do to enable the talking ?
1) Is there any setting I can do in the native MQ java program to enable JMS to read the message an ObjectMessage ?
2) Is there any setting I can do in the JMS program to read the JMSbyteMessage as a ObjectMessage ?
Much thanks and regards. |

I've never tried to write an object with the java api and pick it back up with the jms api. I'd guess that there is something inside the RFH2 header that the java isn't setting so that jms can pick it up. I'd suggest one of two things:
1. Write your object out using the jms api
2. Do #1 so that you can look at the message on the queue. Compare it to your java programs message. Fix your program so that the messages are identical. |

I have the similar problem. I send an ObjectMessage and receive an com.ibm.jms.JMSBytesMessage.
Has anybody successed to send and receive an ObjectMessage? |

You can always try to receive the bytes in the message.
Put them into a buffer (if possible as bytestream...)
read the object from the buffer.
Check out what type of object you received and cast accordingly.
Check out your io classes.
Typical java stuff.
O.K. it is not reading from an ObjectMessage but it should allow you to do the trick with a BytesMessage.
Enjoy |
