How to get environment variable?

Hi,

Root is running the tomcat server.
In my jsp page if I use the System.getProperty("user.name")
it gives user name as "root".

How can I get the user name who has opened the page?

You can't. The container knows about himself, his environment, his applications, incoming requests... It doesn't know about the thousand users unix/windows/other account accessing its applications.

You have to make a proper web authentication system in your application to identify your users.

Hi,

Then is it possible to get the user name from the browser's user profile?

What's a browser's user profile ? Don't forget that JSP is server-side.

Hi,

Ok, My requirement is poping up an alert which is
user dependent. I can use cookies for that. But javascript and html page
can not give me user data. How can I do that?

So once a person logs in and opens a browser is there any way to capture
his user id?

No. As I said, you have to make a proper login mechanism in your application.

Thanks a lot.
