Hi All,
I found the solution myself.Here is a summary of what I have done:-
I have a tomcat and Jboss installed on two different machines.I am
making a call from a web application deployed on tomcat to a web
service deployed on JBoss App Server.
This is not possible through AJAX because XMLHttp doesnt allow you to
make ajax calls between different domains.
There is a little known javascript trick called script tag monkeying
where you insert javascript from one domain to another domain.Through
this technique we can make javascript calls between different domains.
Below mentioned link is a very good link to understand this concept.

http://www.javaworld.com/javaworld/jw-11-2006/jw-1115-json.html?page=2

The implementation provided on javaworld is based on JSON but this
implementation is possible without JSON as well.

Let me know should you need any more help.

Thanks
