The full sources for the Alpha3 release of Java/HotJava are available via anonymous ftp.
If you are interested in the source release, we encourage you to skim the Source Release FAQ page, below. There we try to give a layman's view of our source license agreement. The actual source license text is the final word, though.
The sources in the Source Release have only been compiled on a Solaris 2.X SPARC-based machine. Porting Java or HotJava is not trivial and represents a significant commitment of time. If you are interested in porting Java or HotJava, be sure to read the Information on Porting page, below, for some important perspective.
