Need help with the above error.
I've a mbWelcome.jsp which has the following POST action:
<form name="mbWelcome" method="POST" action="/servlet/LoginServlet">

And the web.xml lines for this servlet are:

<servlet>
<servlet-name>LoginServlet</servlet-name>
<display-name>LoginServlet</display-name>
<servlet-class>minibank.web.LoginServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/servlet/LoginServlet</url-pattern>
</servlet-mapping>

I've LoginServlet.class file in Tomcat installation webapps/MiniBank/WEB-INF/classes/minibank/web/LoginServlet.class

When I submit from mbWelcome.jsp, the LoginServlet action not being invoked, Tomcat is not able to see the class LoginServlet, and giving error in the subject. I think some thing is missing in my configuration, can any one explain this behaviour.

thanks.

You don't need the 'servlet' keyword in your url.
Try:
<form name="mbWelcome" method="POST" action="LoginServlet">

"java_r",

We're pleased to have you here with us on the Ranch, but there are a few rules that need to be followed, and one is that proper names are required. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!

I've tried with the following: <form name="mbWelcome" method="POST" action="LoginServlet">

It did not work. The URL it looks for the servlet now is: http://localhost/MiniBank/Jsp/LoginServlet

Basically, this corresponds to same directory where the mbWelcome.jsp exists. I've brought up mbWelcome.jsp using http://localhost/MiniBank/Jsp/mbWelcome.jsp

For some reason, it looks for the Servlet class in the local dir. I thought adding the following lines to web.xml would make it look at: webapps/MiniBank/WEB-INF/classes/minibank/web/LoginServlet.class

web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">


<web-app id="WebApp">
<display-name>MyBankWeb</display-name>

<servlet>
<servlet-name>LoginServlet</servlet-name>
<display-name>LoginServlet</display-name>
<servlet-class>minibank.web.LoginServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/servlet/LoginServlet</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>mbWelcome.jsp</welcome-file>
</welcome-file-list>
</web-app>
-------

I think, some how the URL is not able to be mapped to the correct location of the class.

thanks.

It needs to match the url-pattern (but without the beginning slash.
Sorry, I did not notice that you had /servlet in your mapping.

<url-pattern>/servlet/LoginServlet</url-pattern>

Try:
<form name="mbWelcome" method="POST" action="servlet/LoginServlet">

The slash at the beginning will cause your browser to omit the contextPath.
This is probably what the issue was.

I did not realize the issue with the starting slash, I've corrected that. However, that did not change any of the behaviour ( I did restart Tomcat).

Now jsp has: <form name="mbWelcome" method="POST" action="servlet/LoginServlet">

web.xml has:
<servlet>
<servlet-name>LoginServlet</servlet-name>
<display-name>LoginServlet</display-name>
<servlet-class>minibank.web.LoginServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/servlet/LoginServlet</url-pattern>
</servlet-mapping>

This is first time writing JSP/servlet app for Tomcat, I don't have a working example to compare, so it is mysterious for me to how to make Tomcat run my servlet class.

Appreciate all your time.

If you want some examples, look at http://simple.souther.us.
It's a collection of demo apps, packaged as war files that can be deployed in a running instance of Tomcat with a couple mouseclicks.
