I have to include this page in my index.jsp so that drop down will create dynamical.

I want to include my page here

A couple thoughts for you.

This is usually done with an ajax request rather than a direct include like this. This allows you to refresh the data at any time and keeps better separation between your server side and client side code. It looks something like this:

xmlhttp.onreadystatechange = function() {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        cell4.innerHTML = xmlhttp.responseText;
    }
}
xmlhttp.open("GET","getdata.jsp",true);
xmlhttp.send();

Alternatively if you really want to include the jsp file like this you'll need to include it from a jsp file as well. Currently your script is most likely in a ".js" file. Your webserver will not process this like a jsp file and your include will be ignored. You can change this to a ".jsp" and update the script tag's src attribute. I don't recommend this approach however.
