Re: javax.jms.MessageFormatException when ObjectMessage.getObject()

[Tomáš Koutný]

I solved this problem by putting transmitting class (Event) into orion's lib directory. It's not clear solution, but it works. I realized that bean's classloader knows the where the class Event is, but message's classloader knows only path to orion's lib.

When running line 2, I get javax.jms.MessageFormatException: com.cleverlance.cmds.comm.Event   Class Event is very simple:       package com.cleverlance.cmds.comm;       public class Event implements java.io.Serializable {             public Event();       }   Do you know what's wrong? Thanks.
