Fibo tutorial - HTTP 500 error javax.servlet.ServletExceptio

[lsalse]

Dear all,

I am new in j2ee and I tried the Fibo tutorial to experiment JBoss-Eclipse IDE.

I followed exactly step by step what is required in the pdf ; Everything resulted fine in Eclipse but the execution of the apps throws an HTTP 500 error :

javax.servlet.ServletException: Lookup of java:/comp/env/ failed
tutorial.web.ComputeServlet.init(ComputeServlet.java:54)
org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:44)

org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:683)
java.lang.Thread.run(Thread.java:534)


I wonder what is wrong in my server configuration or what is missing in the files web.xml or jboss-web.xml ?
Actually both files contain a lot of comments and very few tags ...

Someone could give an help ?

Kind regards,
Laurent

Provide the lookup code and web-app.xml and jboss-web.xml files related to the problem... But I think your problem is due to you have written somewhere java:/comp/env/ and you have to write java:comp/env (without the first /...).

I changed java:/comp/env/ into java:comp/env, without success ...

That might come from version incompatibility ...

Thanks for your help

If it wasn't your problem, if you don't copy your web-app.xml, jboss-web.xml, jboss.xml, ejb-jar.xml and the lookup code, I think not much people can help you...
