User development, A new message was posted in the thread "Receiving message instanceof org.jboss.jms.message.ObjectMessageProxy in MDB": http://community.jboss.org/message/529703#529703 Author : slekha s Profile : http://community.jboss.org/people/slekha Message: -------------------------------------------------------------- Hi, In my application,a JMS client (using JBOSS client jars) publishes messages of Object type to a queue configured on JBOSS 5.1.0 GA . The message received by JBOSS is of type *org.jboss.jms.message.ObjectMessageProxy*  and *NOT* *javax.jms.ObjectMessage* . Hence in MDB , I am having to check +if(message instanceof org.jboss.jms.message.ObjectMessageProxy){}+   Since the application is required to be portable to other application servers , it is desirable to eliminate JBOSS pacakge dependecies.Instead of the above check , I would like to have**+if+ **  **+(message *instanceof*+ +ObjectMessage){}+  Please let me know how to address this.   Thankyou! -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529703#529703
