JSPWiki is developed and run on Sun's JDK versions. For various reasons, 
someone might want to use [alternative Java implementations]. Please list your experiences
here.

[ebu]: A hard-core free software person asked me about JSPWiki with 
a free Java implementation. Any experience out there?

[SantiagoGala] 20030203 Tomcat does not run with kaffe (the only free Java VM I'm aware of). 
It needs some patches. Don't know about other Servlet Engines. But you can use simple, non 
J2EE alternatives for servlet and jsp container. I think it would be possible, but slow and 
would surely need patches all around.

[DaliborTopic]: See [RunningTomcatOnKaffe] to get Tomcat to run on [Kaffe]. The rest of the 
installation follows from [LinuxInstall].

!Sun JDK 1.5

No known problems.  This is the minimum requirement for JSPWiki 2.8.

!Sun JDK 1.4

No known problems.  This is the minimum requirement for JSPWiki 2.4.

;:''Problem fixed in 2.0.21.''

!Sun JDK 1.3.1

JSPWiki 2.2 and earlier run with JDK 1.3. Later versions require JDK 1.4.
