Hello, I am using Netbeans 6.1 and JBoss 5.0.0.CR2.
I am trying out an example with a stateless session bean and servlet, but have
some problems.
The error message:
HTTP Status 404 - Servlet QuatronServlet is not available
---------------------------------------------------------------------------------
The console output:
*** CONTEXTS IN ERROR: Name -> Error

Thanks a lot for any answers! By the way, when should I use <ejb-link> and when
just ?
