Use the following applet to test out your JTablet installation.
The applet should display JTablet Test v0.3 (plugin v.:0.9.5 BETA) at the top if JTablet is correctly loaded. If JTablet is functioning correctly, you should be able to draw with varying brush stroke by using your pen stylus on your tablet. Any errors or problems detected will be displayed at the bottom of the applet.
