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.
