well this is my small bean which is supposed to get the system user name in my jsp page but what happens is that every time my jsp page loads it gives an exeption that there is "no property associated with parameter systprop" im a bit confused about this!!! here is my code..
import java.lang.*;
import java.io.*;
import java.lang*;
public class Winuser {
String systprop= "bean" ;
public String getWinuse()
{
systprop = System.getProperty("user.name");
return systprop; }
}
WHAT IS THE PROBLEM IN MY CODE, according to bean specs it says that if the beam is used for read only then its enough that there is only one get method???

It wouldn't have helped anyway. All you'd see is the user ID of your server login. This is a property of the local JVM.
Web users don't have user IDs unless they're authenticated, and even then the "user id" depends on what sort of authentication scheme you have. It's not like logging into a LAN.


Customer surveys are for companies who didn't pay proper attention to begin with.

class win{
public static void main(String args[]){
String sys = System.getProperty("user.name");
System.out.println(sys);
