Subject: Re: Help needed in building xruby (for java newbie)

Dear Douglas,

thank you for responding.
I actually verified that javac is on my system, and
can be found by the system to compile a "Hello-World"
program in java.
So  I don't think that the $JAVA_HOME
variable is the problem here anymore, but I am a java
newbie, so I don't understand what could be wrong otherwise...

Please, Java experts,  help me again...

Best regards,

Axel
