Can't run Duke's Bank application

[choikim]

I tried to run Duke's Bank application. I downloaded all the necessary files and installed all the tools and ran ant jboss-build.xml script. I followed instructions on Chapter 4. The Duke?s Bank Application on Getting Started with JBoss 4.0 documentation. I checked all the java class files, ejb, and I saw JBossDukeBank.ear file in the deploy directory. I also could run the standalone application using ant -f jboss-build.xml run-client command.
However, I COULD NOT RUN THE APPLICATION FROM THE WEB. When I type the url ( http://ip:8080/bank/main ), it doesn't do anything or show anything.

Can someone help me how to run the Duke's Bank application?

Before I successfully ran helloWorld.jsp after I made examples.war directory and WEB-INF directory and .xml files under that.

I appreciate the help in advance.

You didn't give us much information about what went wrong. Have a look at the Jboss log (server.log in the serverdefault/log directory) and search for "ERROR".

If you are using update 4 of the J2EE Tutorial, see the following topic
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=59000
and try update 2 instead, which can be downloaded from the same page at the Sun Microsystems site (http://java.sun.com/j2ee/1.4/download.html#tutorial).
