Hi,

I have developed a MDB to listen to the message recieved at Topic. My MessageProducer.java class publish ObjectMessage on Topic. This ObjectMessage contains java.util.HashMap object which in turn contains two key-value pair, one as String Value and another one as User Defined Java Object(UserInfo.java).

I want to pass whole UserInfo.java object into Topic which contains javax.http.HttpSession object.

But while getting the message from Topic i am recieving only partially UserInfo Object, i am not able to get the HtppSession object from UserInfo object that was present in UserInfo object while publishing it.

I get Null pointer exception for userInfo.getHttpSession() method call.
And same call works before publishing message.

Can any one help why it is so happening?
 
It is sorta covered in the JavaRanch Style Guide.
