Problem in with Tomcat 5.0 to run jsp

5.0 to run my jsp which contains the code to get windows username.
out.println("Username : "+System.getProperty("user.name"));
out.println("Username : "+System.getenv("username"));
Output of the above code is
Username : SYSTEM Username : null
If I use the same code is run using Tomcat 5.5 then I get correct output.
I also came to know that If I use
then I get correct output(No need of Tomcat).
But in my application I got to use
. I even tried for calling java method(which returns username with System.getProperty())in a JSP, after that also I get the wrong output.
Can any one tell me why Im getting this problem?
Is this problem related to versions of Tomcat?
Thanks in advance

No, it's not a problem related to Tomcat.
You expected the Java code to run at the client machine, but it doesn't. It runs at the server machine. That's your misinterpretation here.
If you want to get the client's user name by System.getProperty(), then you obviously need to run Java at the client machine. You can do this using a signed
or a web start application.
It is sorta covered in the
JavaRanch Style Guide
