Using gzip in jsp files

I am trying to speed up the performance of my application . I am using firebug and Yslow has recommended some techniques.
One of the issues we have is that there are around 24 java script files which are loaded every time. That mean 24 requests.
We cannot club them into one from maintainability perspective .
So the other option is compress these files using gzip. I downloaded the utility from gzip site http://www.gzip.org/

I am can compress the file using gzip and it is transmitted successfully.

The problem arises when app tries to use validation inside these files. The java script code is not executed.
I think the reason could be that the browser is not able to decompress the file

This was original code in jsp

<script type="text/javascript" src="<c:url value="/scripts/lib/validate.js"/>"></script>

the .js has been replaced with .js.gz
<script type="text/javascript" src="<c:url value="/scripts/lib/validate.js.gz"/>"></script>


I am not sure if we would have to manually gzip the files or we enable some flag in server which serves the files as gzip files from server.

Any help is appreciated

That's not how gzipping from the server works AFAIK--you're just sending a binary file without providing the client any way of knowing what it's receiving.

The canonical way to do this is to use a gzip filter, of which there are an abundance.
 
I agree. Here's the link: http://aspose.com/file-tools
