Before installing Kawa, you will need a working Java system. Kawa has been reported to work with JDK from 1.1 through 1.6, Kaffe, Symantec Cafe, J++, and GCJ. The released Kawa jar file assumes JDK 1.5 or equivalent functionality. If those features are missing, you may need to build Kawa from source.
