Hi

I have 2 MDB's( MDB1,MDB2 )configured to the same Listener port. Now in MDB2 i made some selection like JMSType='car' and the other i did not modify .

When i run my application, though i have specified the selection all the messages were processed by MDB2.

Now when i specify a message selection for MDB1, the application is working well, means the selection is happening....

Is it how it behaves or did i missed any point over here...

(i have configured MDB's properly in the ejb-jar.xml file through activation-config-property)

My requirement is that if only 1 MDB is the selector it should process messages of that kind only.

Thanks

I don't think 'car' is an acceptable value for JMSType. Read up on using java manual.

You can create your own properties and query on their values. It looks like you are using the JMSEngine and I am not familiar with the performance implication of selector in the WAS JMSEngine environment.

For MQ you should not use any selectors that do not use the correlationId or messageId the "native" way. (Performance)

Enjoy
