JarBreaker is a Java app (not applet) designed to help you keep track of the jar files that accumulate over time on your hard drive. With it's command line interface and JDBC components, you can quickly and easily search for the jar file that contains the class file you need to slay that dreaded 'NoClassDefFoundError'. Requires Java 1.2.2, and a JDBC compliant DB with driver (comes configured for postgresql by default). The DB must handle transactions.
