Hi,
I have created one small demo app and when I deploy it to JBoss 4.0 (Tomcat
5.5), although I have mapped my servlet to >demo/DemoServlet<, I can't
access it with browser. I got 404 HTTP error. I have spent whole day trying
to figure it out what is wrong. I could send all sources and binaries to
someone willing to help. Some files are in the attachment. Please help me.
Thank you,
Milan
