Re: any java expert on 64 bit ?

xnap didn't get installed properly? I've never used Xnap but it looks
like your system is missing a .jar file someplace (the error basically
says what it says - could not load a startup class - the class with
the main() method or something that is referenced by it - from
whatever folder). You could open the xnap.jar with some zip archiver
and look inside the manifest file - it'll tell you the main class,
which I guess is org.xnap.XNap - as well as any other jar files that
Xnap is supposed to have available for it to run). If XNap is
maintained properly then you should probably find their installation
or troubleshooting instructions on how to deal with this.

On the surface, It doesn't look like this issue has got anything in
particular to do with FC4 or java VM.
