[Qt-jambi-interest] designer not finding JVM

[Derek Fountain]

I've correctly set up the QtJambi 4.4 preview on my SUSE box at home,
but I'm having trouble getting designer to run on my Ubuntu box at work.
When I run the designer.sh script it says:

>designer.sh
QtJambi: failed to locate the JVM. Make sure JAVADIR is set, and
pointing to your Java installation.
Jambi: failed to initialize...
QtJambi: failed to locate the JVM. Make sure JAVADIR is set, and
pointing to your Java installation.
Jambi: failed to initialize...

I don't appear to need a JAVADIR variable at home, but I set one up at
work anyway:

>echo $JAVADIR
/usr/lib/jvm/java-6-sun/jre

>ls $JAVADIR
bin  COPYRIGHT  javaws  lib  LICENSE  man  plugin  README
THIRDPARTYLICENSEREADME.txt  Welcome.html

It all looks right. If I copy classes from home to work they run quite
happily, so I think I've got everything else set up right. So what is
the designer after at work that I'm not giving it?
