Java EE (Java Enterprise Edition) General Discussion

I have Oracle JDeveloper Studio Edition Version 10.1.3.2.0.4066.

I am having problem with my message-driven bean examples. I have two
files, LogBean.java(MDB) and LogClient.java. Both the files are compiling
successfully without any warnings and errors. However, when I am trying to
run the program I am getting Exception: java.lang.InstantiationException: No
destination location set for message-driven bean LogBean.

This is Exception:

[Starting OC4J using the following ports: HTTP=8989, RMI=23892,

Please help.

Thank you.
