Hi I made a sample to see if I knew how to deploy an application in WAS. It consisted of two simple elements:
a Session Bean called Hello, with a print method that printed "Hello!" to the standard out and returned this stringa servlet that called the session bean and printed the result in the browser. Inside WSAD it ran fine, but when I deployed it to WAS it gave the following error:
this is the browser message:
"Error 500: Failed to load target servlet [
Test]"
this is what I got from the log:

Apparently, the server isn�t finding the class of the Home interface, although I don�t know why. If I remove from the servlet where it calls the
EJB, the application runs fine and prints "Hello!", so the problem is not the servlet, the HTTP server, or the plugin configuration.
I�m using the WAS 4 Test Environment inside WSAD 5 and my WAS is 4.0.1 Advanced Edition, can somebody help me? I really don�t know what�s happening. If anybody wants, I can show the source code, I didn�t put the code here because the message would be too long. Any help is deeply appreciated.
Sincerely,
Francisco
