Java Programming

Here is the problem :

There is a jar, called ijpos.jar. It contains a property file, called jpos.properties.
Now, I make a main class, below is its code:

 public static void main(String a[]){
        MySigCapMain m1 = new MySigCapMain();
        m1.newInit();
    }
    public void newInit()
    {
        System.setSecurityManager(null);
        try {
            writeToConsole("Opening SIGCAP");
            sigCap.open("i6780_SigCap");
            sigCap.addDataListener(this);
            sigCap.addErrorListener(this);
            writeToConsole("Claiming SIGCAP");
            sigCap.claim(100);
            sigCap.setDeviceEnabled(true);
            sigData = new Vector();
            iLen = 0;
            sigCap.beginCapture("Sigform");
            sigCap.setDataEventEnabled(true);
            writeToConsole("Init completed");
        }
        catch(Exception exception)
        {
            writeToConsole("Exception\t" + exception);
            exception.printStackTrace();
        }
        
    }

I have included the ijpos.jar in the project properties.

This code runs perfectly as desired.

Now, I make an applet and write the code of the main method above, in the init method of the applet.
I made a jar out of it, and include it in the archive attribute of the applet tag. I also include the ijpos jar in the archive. All the jars are signed jars, and also the security manager for the System is set to null.

The problem here is that it is not able to find the jpos.properties file.

Please help.

Thanks,
