Hello folks,

I posted this message 2 weeks ago and nobody replied. Could you, please, have a
quick look at it?
It might be something very simple that I am missing. Thank you!

I am trying to run the web tier of the java pet store distributed application
from sun. However,
I get an error. Thank you very much in advance!

I go to <webapps>/casting (where application is installed) and in the
browser window I get:
========================================================
Error: 500
Location: /casting/control/main
Internal Servlet Error:
java.lang.NullPointerException
 at
org.apache.tomcat.core.ContextManager.handleError(ContextManager.java,
Compiled Code)

org.apache.tomcat.core.ServletWrapper.handleRequest(ServletWrapper.java,

 at java.lang.Thread.run(Thread.java:479)
Please notify the administrator. Thank you.
========================================================

In my "welcome" file I have the following link: <a href="control/main">

In the web.xml file I map the /control/* as follows:
=============================
  <servlet>
    <servlet-name>castingEntryPoint</servlet-name>
    <jsp-file>Main.jsp</jsp-file>
  </servlet>
  <servlet-mapping>
    <servlet-name>castingEntryPoint</servlet-name>
    <url-pattern>/control/*</url-pattern>
  </servlet-mapping>
=============================
Note: Main.jsp is in <webapps>/casting

In my server.xml I have the context mapping line:
================================================
        <Context path="/casting" docBase="webapps/casting" debug="9"
reloadable="true" >
        </Context>
================================================
