Deploying Jsp's on tomcat

We  have to create a web based application

1. we made a war fike of our application and when we unzipped it it created a folder in which all the classes,beans and jsp's existed.

2. We put a line in "server.xml" for the <context>
So now when we type..
http://localhost:8080/Webapp
It shows the directory listing.
This goes on till
/usr/tomcat3/jakarta-tomcat-4.0.3/Webapp/src/docroot
When we click on docroot we get the index.html page
Also when we give
/usr/tomcat3/jakarta-tomcat-4.0.3/Webapp/src/compose.jsp
we get the page.

3.But still the pages which refer to servlets can't be displayed
I think the problem is with web.xml
There is one web.xml also for our package .. please lemme know what exactly should we put in it so that it can access the beans
Like there is
<servlet>
<servlet-mapping>
there are tld's.
so what exactly should we do.

Your web.xml should be in the WEB-INF directory.  You can define a welcome-file that you can point to your JSP.

Typically, here's how I structure my "webapps"

$TOMCAT_HOME/webapps/
    --myApp/
        --index.jsp
        --*.jsp
        --images/
            --*.gif
            --*.jpg
        --styles/
            --*.css
        --scripts/
            --*.js
        --WEB-INF/
            --*.xml
            --classes/
            --lib/
            --tlds/

Good examples can be found by looking at some struts examples: http://jakarta.apache.org/struts

Here is the web.xml from the struts-example application:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
  "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

<web-app>


  <!-- Action Servlet Configuration -->
  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
  </servlet>


  <!-- Action Servlet Mapping -->
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>


  <!-- The Welcome File List -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <!-- Application Tag Library Descriptor -->
  <taglib>
    <taglib-uri>/WEB-INF/app.tld</taglib-uri>
    <taglib-location>/WEB-INF/app.tld</taglib-location>
  </taglib>

  <!-- Struts Tag Library Descriptors -->
  <taglib>
    <taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri>
    <taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
  </taglib>

  <taglib>
    <taglib-uri>/WEB-INF/struts-html.tld</taglib-uri>
    <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
  </taglib>

  <taglib>
    <taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri>
    <taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
  </taglib>

</web-app>
