openoffice-2 problem with JDK

[mr. phreak]

I get this when i 'make':

checking whether to build with Java support... yes
checking the installed JDK... configure: error: JDK is too old, you need
at least 1.3
===>  Script "configure" failed unexpectedly.

Please report the problem to openoffice at FreeBSD.org [maintainer] and attach
the
"/usr/ports/editors/openoffice.org-2/work/OOG680_m9/config_office/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. an `ls /var/db/pkg`).
*** Error code 1

Stop in /usr/ports/editors/openoffice.org-2.

Still I have JDK 1.5:

fbsdlap# pkg_info | grep jdk
diablo-jdk-1.5.0.07.01_9 Java Development Kit 1.5.0_07.01

My version:

fbsdlap# uname -rspi
FreeBSD 7.0-RC1 i386 GENERIC


Any suggestions on what to do? I've already send openoffice at freebsd.org
a mail, but no reply so far.

Regards
Johan
