Hi amit, krishnaraj ,
For future support and other help we should go for
Tomcat. I also hung up with jswdk for long time, but lately decided to use Tomcat since Sun has turned over the jswdk to Apache. Tomcat is reference implementation of jswdk from Apache. So go for Tomcat.
For instructions on download and installation, Satya's post will help.
Satya's Tomcat installation instructions.
