java in OO.o2

[G Rajesh <ganesanrajesh gmail com>]

Hi,
I use fc4 and I recently upgraded my OO.o from 104 build (given with
CDs) to final release through Yum. Earlier I had installed jre (as a
tarball linked through alternatives command). 104 build has promptly
detected jre1.5 but this upgraded OO.o doesn't. I need OO.o base badly
to work. Can some one help me out?
Thanks in advance.
Regards,
Rajesh
