Is there a standard way for me to add my own custom object to a Map and then have it properly marshalled in a MapMessage? Currently I get the Invalid Object Type message. I noticed that WebSphere has a solution but I am looking for something that is not bound to a particular AS, if there is no such method, maybe something supported by JBoss would work.

How to do it in WebSphere:

    A JMS map message’s map only supports primitives and strings (and their arrays) as values.
    From the javadoc:

    The names are String objects, and the values are primitive data types
    in the Java programming language.

    You would be better off using an ObjectMessage and write your serialized objects to a map and then send the map as the payload of the ObjectMessage. That way, you can still have the name/value map access style but without the limitation of types.
