Cannot run A JSP file in a WAR (Apache Tomcat 5.5.20)

[satishkumar]

Hi,
Iam using Apache Tomcat 5.5.20.
Iam trying to deploy a web application named "ShowLifecycles".It has one JSP file named "ShowLifecycles.jsp" and a .Class file named "MyAppListener.class".
I have packaged them as follows:

1)<TOMCAT-ROOT>/webapps/ShowLifecycles/ShowLifecycles.jsp
2)<TOMCAT-ROOT>/webapps/ShowLifecycles/WEB- INF/classes/examples/MyAppListener.class

My web.xml looks like this:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">

<display-name>ShowLifecycles</display-name>
<description>An example of how to use lifecycle events</description>
<listener>
<listener-class> examples.MyAppListener </listener-class>
</listener>
</web-app>

When I point my browser to

http://localhost:8080/ShowLifecycles/ShowLifecycles.jsp

it tells

"The requested resource(/ShowLifecycles/ShowLifecycles.jsp) is not available".

MyAppListener implements a ServletContextListener.I have typed the URL in correct case. Another Web application of a similar type was able to execute a JSP file in it.

I have tried using <jsp-file> and <servlet-mapping> in web.xml. Still it doesn't work.
I would be grateful to receive a prompt reply.
