code not working

the following line of code is not working
<%
Runtime.getRuntime().exec("word.js");
%>
the code for word.js is:
var objShell=WScript.CreateObject("WScript.Shell");
var objWord=WScript.CreateObject("Word.Application");
var objDoc=objWord.Documents.Add();
objWord.visible=true;

I think you are getting a bit confused between whet happens on the server (where your web application and the servlet container are located) and on the client (the machine running the browser).
All the Java code that you run as part of a JSP (such as calling runtime.exec() ) happens on the server, as the page is being generated - before it is sent to the browser. I'm guessing that you actually want to run this javascript code in the browser, which is located on the client machine.
The easiest way to do this is to just print the Javascript statements to the JSP page, so that the browser will run them when it receives the page:
mypage.jsp:

Is that more like what you are looking for?
