Help with JPOS

27 Aug 2006 22:39:40 -0700

  I've written a fairly simple java class that handles a few things
with a signature capture device using java comm. When run under Linux,
It works without error when a single user executes it. However,
whenever a second user executes a instance of the class, errors are
thrown - typically an ArrayOutOfBounds exception.

  I think it is related to the way in which the class is instantiated
when executed, but I'm clueless. I've posted the primary code below.
BTW, it runs headless from the command line rather than a GUI.

  Any hints?

import java.awt.event.*;
import java.awt.image.BufferedImage;
import java.beans.*;
import javax.comm.*;
import java.util.*;
import java.lang.Thread;

public class JSig implements DataListener

    public static void main( String args[] )
        JSig js = null;

             js = new JSig( args );
        catch( Exception e )
            System.out.println("JSig:Error in execution: " +
            System.exit( 1 );
