Receiving Java Objects over JMS

Is this really the way to receive POJOs with JMS?

public void onMessage(Message msg) {
     ObjectMessage objMsg = (ObjectMessage) msg;
     if(objMsg.getObject() instanceof <<sometype>>) {
        //do something 
     }
 }

Do I have to cast to ObjectMessage. Actually then i have to check if msg is castable to ObjectMessage too.

or do i miss something?

thx

Solution

  • AFAIK, that's it. It's pretty rare to mix different message types, and different object types inside the message, in a single destination (queue or topic), though. So you might skip the instanceof checks if you know that only ObjectMessages containing SomeType objects are expected.
