Re: [JBoss-user] Please, please , please
it is all in the deployment descriptors... first web.xml the relevent parts first to map the servlet hello simple.helloServlet hello /hello this names out helloServlet.class hello, then maps ALL calls to /hello to that servlet so http://localhost:8080/hello results in a call to the helloServlet.class. now... index.jsp tells us that our welcome files... most people think of index.html as being the welcome file the welcome file is index.jsp. so... IF we had a directory hello that contained index.jsp then http://localhost:8080/hello/ would result in that index.jsp showing. however we dont have that directory. now the application.xml first we need to tell about our web application webapp.war / here we map this web application to / so a call to http://localhost:8080/ will result in our index.jsp showing. if you want to map to hello then change the / to /hello then to see JUST the servlet you would call it like this http://localhost:8080/hello/hello and to see the index.jsp you would call http://localhost:8080/hello/ Hope that clears up some things.

I think Richard was referring to the interest example being slightly more than a bite for a new user.

For instance I now know that I don't need to manually change the server.xml file to deploy applications. But I still don't know why /hello works, and hello/ or /hello/index.jsp does not.

Just give beginners examples that work with a completely vanilla install and we can improve our knowledge over time. How this benefits the creators of JBoss is we can roll out JBoss Apps on just about anything that will run Apache. That starts to make JBoss ubiquitous and opens the door to high level consulting and EJB component libraries. Hell I'd pay now for a 1-2-3 setup for a MySQL/JDBC connectivity EJB installer.
