Hi all,

I got the following requirement:

Business Object <--> EJB|Java MQWF API|Java Agent <--> MQWF

1. A business object talk to MQWF through EJB
2. An EJB may return a MQWF object, such as ReadWriteContainer/ActivityInstance, back to the business obejct

Is it possible to do the above scenario? How can a EJB return a MQWF object back to the business object? Is there any example for this?

Thx in advance

This is not possible in a JMS scenario.
You will need to have the EJB instantiate the object you want returned, or have it declared in JNDI space and acquired/instantiated on startup of the EJB.

My advice would be to have an EJB specifically for handling all MQWF calls, thus encapsulating the specific MQWF API calls for the application.

Have fun.
F.J.
