Hi all,
I'm trying to run an example which display fist - a login page. Then there is a call to servlet which retrieves user name and finally displays welcome message to the user.

My directory structure..
1) Root directory : TOMCATE_INST_DIR\webapps\onJava
2) login.jsp : TOMCATE_INST_DIR\webapps\onJava\login.jsp
3) welcome.jsp : TOMCATE_INST_DIR\webapps\onJava\welcome.jsp
4) web.xml : TOMCATE_INST_DIR\webapps\onJava\WEB-INF\web.xml
5) servlet class : TOMCATE_INST_DIR\webapps\onJava\WEB-INF\clssses\com

My login.jsp include code to call servlet:
<form name="loginForm" method="post" action="servlet/com.onjava.login">
My include cole to redirect requst to welcome.jsp

I've made followin entry in TOMCATE_INST_DIR\conf\server.xml
<Context path="/onJava" docBase="onJava" debug="0" reloadable="true" />

Now when i invoke my login page : http://localhost:8080/onJava/login.jsp
i get login screen where i supposed to provide user name. once i do this,
i invoke login servlet (com.onjava.login.class), which should display welcome message (welcome.jsp)

But while invoking servlet i get following error
HTTP Status 404 - /onJava/servlet/com.onjava.login

type Status report

message /onJava/servlet/com.onjava.login

What's wrong with the configuration (Above structure works fine if i put all my code under ROOT dir).

I've followed example :

Please guide me..

I think that you need to enable the ugly servlet invoker.
Open tomcat's /conf/web.xml. Look for "invoker" in this file, and uncomment the invoker servlet. Reboot Tomcat, and retry.

Uncommenting the invoker servlet is a bad way to start out, in my opinion.
Can you post the contents of your web.xml file?

Also, if you want an example of a proper webapp, you can download any of the war files from my site and drop them in your webapps directory.

Content of web.xml : TOMCATE_INST_DIR\webapps\onJava\WEB-INF\web.xml

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

<web-app xmlns=""

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
