    Hi. What do you have problem? You can create button. When you click it show new window.
    Java Code: 
    <INPUT type="button" value="New Window!" onClick="window.open(needUrl,'mywindow','width=400,height=200')">
    Where needUrl - url your servlet It after run redirect to jsp. It is easy.

    Hi Petr,
    Thanks 4 reply,

    I tried to mention path of a servlet as mention below, but is not working. What is the mistake i am doing?
    Java Code: 
    <INPUT type="button" value="New Window!" onClick="window.open(RequestProcessor,'mywindow','width=400,height=200')">

    My Servlet info

    Java Code: 
    <servlet-name>RequestProcessor</servlet-name>
    <servlet-class>com.retailbank.controller.RequestProcessor</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>RequestProcessor</servlet-name>
    <url-pattern>/Module.do</url-pattern>
  </servlet-mapping>

    Also there are some hidden parameters that the servlet uses to pass the request to appropriate class.

    Java Code: 
    <input type="hidden" name="moduleName" value="account">
<input type="hidden" name="trasferType" value="transaction">

    I hope the request object will carry this parameters.

    You need replace RequestProcessor to "/Module.do".
    About parameters you can create function js. which build need url.
    for example
    Java Code: 
    var needUrl = "/Module.do?"
function buildUrl() {
    var moduleName = document.getElementById("moduleIdEl");
    needUrl += "moduleName=" + moduleName.value;
    var trasferType = document.getElementById("trasferTypeIdEl");
    needUrl += "&trasferType=" +trasferType.value;
}

...
window.open(needUrl, ...

    Sorry for the delayed response.
    But the thing is not actually working.

    Java Code: 
    var moduleName = document.getElementById("moduleIdEl");
    Nothing is getting populated under var moduleName . I also tried getElementByName but not working.
    Java Code: 
    var moduleName = document.getElementByName("moduleName");
    One more error i get after directly constructing the url like
    needUrl=/Module.do?accountName=account&transferType=transac tion

    HTTP Status 405 - HTTP method GET is not supported by this URL

    Java Code: 
    public void doPost (HttpServletRequest req,
			HttpServletResponse res)
	throws ServletException, IOException, NullPointerException
	{	
		dispatcher = getServletContext().getRequestDispatcher(reqMapperObj.mapRequest(req));
		if(dispatcher!=null)
			dispatcher.forward(req,res);
		else			
			System.out.println("No Dispatcher found");
	}

	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
	  {
	    doPost(request, response);
	  }


    This is the jsp for your ref

    Java Code: 
    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"

<%@ page import="com.retailbank.domain.accounts.Statement,com.retailbank.domain.accounts.Transaction,java.util.List,java.util.ArrayList" %>
