[jboss-user] [Remoting] - Re: InstantiationException with client passed proxies

[cdelashmutt]

I tried making the MBean use the new 2.0.0.CR2 release, but I ran into some strange problems.  So to help isolate things, I ran the server component outside of the App Server.  Basically, I just added a main method to explictly call the startup methods which create the Transporter server.  The client remained the same.

I can now send a proxy to the server for the Person object, and it can work with it.  However, when the server tries to call a method (void setAge (int age)) on the Person object proxy that was passed in, I get a ClassNotFoundException:

I can't believe that remoting isn't able to sent primitives, so I must be doing something wrong again.

Any more thoughts?
