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?
