Hai All

I have 2 web applications in tomcat server. When i login from first webapplication it goes to Index page, in that page we give a link to some action in 2nd application. what we need is common session which we cant achieve sharing common session object. Is it possible by cross context in server.xml of tomcat. If so how its possible. help me out....

No, per the servlet spec, sessions are by user, by context.
In other words, each context has a separate session for each user.

There are ways to share information between contexts in Tomcat but they are not necessarily spec compliant; meaning the code may not work the same way in another container.

See:

It is sorta covered in the JavaRanch Style Guide.
