Hi,I have a problem when make some change to the source file. I rename source file NamingServer.java in package "org.jnp.server" to MyNamingServer.java and change type "NamingServer" in source file Main.java to "MyNamingServer". I recompile the source file of JBoss3.2.3 and it suceeds, but when I run the JBoss, there are the following exceptions.

Can someone help me?
Thanks in advance
Regards, Du
