Thanks David. I have added the code tag. :)

This doesn't really have anything to do with Struts yet, so I'm moving it to HTML/JavaScript.

1) Why are you using the "new" keyword? You should just be setting xmlhttp to the results of calling the function.
2) Why are you doing Ajax "by hand"? Use a JavaScript framework--it will make you life *much* easier.

Thanks David I got it done. This was my first post on Javaranch
and really pleased by your prompt reply.

Glad we could help, and that you worked it out :)
