my servlet code is

package webnew;
import java.io.PrintWriter;
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageProducer;

import javax.naming.NamingException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class WelCome extends HttpServlet
{
/**

private static final long serialVersionUID = 1L;

private ConnectionFactory cf;

private Queue queue;

@Override
public void init(ServletConfig config) throws ServletException {
super.init(config);

}
protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, java.io.IOException, NamingException
{
try
{ Context ctx=new InitialContext();
cf = (QueueConnectionFactory)ctx.lookup("MQConnectionFactory");
queue = (Queue)ctx.lookup("QIbm");
Connection connection =cf.createConnection();
Session session =connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
MessageProducer producer =session.createProducer(queue);
Message msg;
TextMessage message =session.createTextMessage();

String var=request.getParameter("msg");
message.setText(var);
producer.send(message);
producer.close();
session.close();
connection.close();
PrintWriter out=response.getWriter();
out.println("<html><head><title>The servlet example </title></head> <body><h1>A simple web application</h1><br/><br/>");
out.println("<input type='submit' value='Read the message from queue'/>");
out.println("</form></body></html>");
}
catch(Exception e)
{
e.printStackTrace();

}

}

protected void readMsgRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, java.io.IOException, NamingException
{
try
{ Context ctx=new InitialContext();
cf = (QueueConnectionFactory)ctx.lookup("MQConnectionFactory");
queue = (Queue)ctx.lookup("QIbm");
Connection connection =cf.createConnection();
Session session =connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
MessageConsumer Consumer =session.createConsumer(queue);

//TextMessage message =session.createTextMessage();
//message.setText("good morning");
Message msg = Consumer.receive();

The code has nothing to do with the problem. You haven't deployed the class correctly. The compiled version of the class should be in the /WEB-INF/classes directory of the deployed application, as WelCome.class in directory /webnew. Or alternatively, it should be in a jar file which is in the /WEB-INF/lib directory.

thanks for reply ,
You are right,i have problem in deployment...now i have created war file in which web-inf contains compiled file of servlet and web.xml...but i m getting new problem while accessing application through html...i m getting error like Error 404: SRVE0190E: File not found: /...my war file contains WEB_INF in that class file ,web.xml ...do i have to include html page in that war??how to and where to include???

Not web-inf, and not WEB_INF, but WEB-INF.

yup its WEB-INF...my html file is like
<html>
<head>
<title>The servlet example </title>
</head>
<body>
<h1>A simple web application</h1>
<form method="GET" action="WelCome">
<label for="name">enter your message here</label>
<input type="text" id="name" name="msg"/><br><br>
<input type="submit" name="submitBtn" value="Put the message into the queue"/>
</form>
</body>
</html>

and web.xml is

<web-app version="2.4"
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">
<servlet>
<servlet-name>welcome</servlet-name>
<servlet-class>webnew.WelCome</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>welcome</servlet-name>
<url-pattern>/WelCome</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>form.html</welcome-file>
</welcome-file-list>
</web-app>

can you please tell me is there any problem with these files?

The class files looks to have not generated properly. Stop the server. Remove the EAR. Now clean and build the project. Start the server. Add the EARs. Do a maual publish. This should mostly resolve the issue.

Additionally, take a look at the http/jvm logs or ffdc logs as well.
