About the Applet
The applet below (if your browser supports Java applets, that is) lets you play around with the gnu.regexp engine by compiling regular expressions and testing them against arbitrary input text (if you like, cut and paste into the input textarea). The applet JAR is about 27K in size, and includes the gnu.regexp library (24K).

Basic Usage
To get started, click the "Match" button using the defaults. You should see two matches found. Turn on the "ignore case" feature and click "Match" again. A third match will be found. Then try your own regular expressions (the applet defaults to a Perl5-like syntax) and input texts.

Troubleshooting
If the applet won't start, you may have an incompatible version of gnu.regexp in your browser's classpath setting (usually the gnu.regexp library will be downloaded for you by the browser). You can remedy this by quitting the browser and adjusting your classpath setting to exclude gnu.regexp before relaunching.
