Hi, I'm pretty sure what you are trying to do can be done. I believe the error is caused by the browser not having the appropriate Java plug-in (JRE 1.2 for Swing). You might also encounter security problems trying to access the filesystem directly from an applet - there's info about this around : http://java.sun.com/security/signExample12/
