[jboss-user] [EJB/JBoss] - RMI Dynamic Classloading

[dubacher]

Hi there.

I have a problem when using the dynamic classloading feature of RMI for a non RMI-Class.

Note: 
- The "WebService" which provides the class is up and running on the port 8083.
- I use jboss-4.2.2

The first problem:
When the class X to be loaded dynamically is sent as instance to the client, the codebase is not set correctly to the WebServer running on port 8083. Instead the codebase comprises loads of "file:/...."-URLs. Therefore when the class X has to be loaded the client does not try to dynamically load the class from the server running on port 8083.
I patched the class MarshalInputStream so that the codebase is set correctly on the client side. After having applied the patch the client now tries to load the class from the server... 

now the second problem:

I sniffed the port 8083. The following HTTP get call is performed:

  GET /org/foo/bar/X.class HTTP/1.1
  User-Agent: Java/1.6.0_05
  Host: delgado:8083
  Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
  Connection: keep-alive

Which is answered by the server with:

  HTTP/1.0 404 Not Found
  Content-Type: text/html
 

I debugged the WebServer code and found out that classloader returned by the call "Thread.currentThread().getContextClassLoader();" is not able to load my class X.


Any hints to my problem are appreciated.

cheers,
marco
