Session gets null on mapping the application

Hello guys,

I am using struts 2 and saving some information in the session. When i try to access the application using the folllowing url
http://www.example.net:8080/MyApp
it works fine.

But i have mapped the application at http://www.example.net. When i am using the application using this url the session gets null.

Could anyone tells me where am i mistaking.

thanks in advance.

Can you explain what you mean by "the session gets null"?

I mean to say that values in the session that i put get invalidated.
I am saving some values in the session but when i try to retrieve those values those it throws null pointer exceptions

i have done apache to tomcat mapping using mode proxy for mapping the url "www.example.com:8080/myapp" into www.example.com. but after mapping i got the session null exception in my application in some place. but it's work fine in my old URL "www.example.com:8080/myapp"

Are cookies enabled? If not and you do not use URL rewriting to include the session ID in the URL, the server doesn't know there already is a session and creates a new one.

Anyway, I'm moving this to Servlets.
