Unexpected ClassCast Exception
Hello people!
I'm using netbeans 5.0 and jboss 4.0.2 to migrate a project from sun to jboss. When I try to use a servlet I have a strange classcast Exception:

The source code of the servlet is
public void init(ServletConfig config) throws ServletException {

ne.printStackTrace();

super.init(config);
