Thank you Eric, I however had to run the serialver tool on a
i386/solaris8 system (I didn't want to install sun's SDK on my
computer, just for the serialver tool). Does the output match
every system ? Is there a posibility that there are different
serialVersionUIDs for different systems?

Thank you,
