Java applet "object does not support this method or property"

Dear all,

I have created one aspx application to get client system information. For getting the client system information, i have created a JNI library.

I have used java script to load a applet jar which in-turns will load the JNI library where the JNI library is located in every client system.

I have tested this application and it is working fine.

For testing purpose, i have hosted my application in two to three system. For eg, Server A, B and C. I had access the server pages in a system (TEST system).

When i access the page from system A and C in the TEST system, the application works fine.

But when i access the page from system B in the TEST system, the java script gives error.

The error is object does not support this method or property in the line Obj.GetUserName().

Sample source is below:

Java script:

document.write('<applet code="Client.Information.class" width="0" height="0" MAYSCRIPT archive="Client.jar" id="Obj"></applet>');

function ClientInformation ()
{
    Obj.GetUserName();
    Obj.GetSystemMemory();
}

Applet jar:

package Client;
import java.*;
import java.io.*;
import java.lang.*;
import java.applet.Applet;
import java.awt.*;

public class Information extends Applet
{
     public native string GetUserName();
     public native string GetSystemMemory();

     static
     {
          System.loadLibrary("ClientInformation");
     }
}

As surfing through internet, updating the java version and clearing the browser cache will solve this problem. But i have tried this.

Please guide me to solve this error.

Thanks for your reply.
