hi everybody
the other day i joined the forum but there are not too
many people there and is slow (for me), so i switch to
the old and proven mail method
i'm new with jboss and ejb and i'm trying to use an
EJB (stateless session) from a servlet but it doesn't
work, i can use it from a stand-alone java program
succesfully
even if i point the browser to
http://localhost:8080/hello/HelloServlet
i get this error
===================================================
Error: 500
Location: /hello/HelloServlet
Internal Servlet Error:
javax.servlet.ServletException: Failed to lookup
java:comp/env/ejb/Hello, this is wrong
