Hi folkz,

I have the Sun JDK 1.3.0 for Linux, beta 9 running on my FreeBSD
4.0-STABLE system. Runs pretty nicely too.

java -version reports:

   bash-2.04$ java -version
   expr: syntax error
   java version "1.3.0beta_refresh"
   Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta_refresh-b09)
   Classic VM (build 1.3.0beta_refresh-b09, green threads, nojit)

The first line with the syntax error is a small problem with
.java_wrapper, but it seems harmless. I had to make some modifications
to the .java_wrapper script to make it work on my system. I've attached
the version I use.

I haven't done much testing yet, but I have tried a single Swing
application. I did notice some differences in fonts, but it all seems to
work pretty nice and fast :)

Wow, soon FreeBSD will be the platform with the greatest number of
working JDKs on it, once we get WINE to work so we can run the Windows
JDKs too, and write an AS/400 emulator, and... and... ;-)

Ernst

P.S.  Thanks go to Victor Salaman how pointed me in the right direction.
      He has been running the Sun JDK 1.3 for Linux for quite a while.
