I have recently joined a Banking Tech group where I see plenty of JSP's, Javascripts and html pages. Is there any way I can reduce the bandwidth utilized by using certain tools to reduce the size of file?
How do I identify the problem areas?

The first thing to do is start measuring to define what part of the whole system consumes unreasonable amounts of resources. The JAMON toolkit can make a start with minimum disruption to the existing system.

If network "bandwidth" is in fact being stressed, you might look into use of CSS and AJAX to reduce the volume of browser requests.

Muni,
You can also use a compression filter on your web app to reduce the bandwidth delivered to render the same content. It's like sending a zip file instead of the full one.

if you use tomcat, jboss, or jetty as your web container jamon can also measure the ammount of bytes sent back to the client. This will allow you to see if any are candidates for a compression filter. A compression servlet filter is very easy to implement and almost always will help or certainly won't hurt.
