For starters there is no libjli.so in Java SE 5.0.

I suspect that reason this works on the command line, but not in the menu,
is that you have set your path to include /usr/lib/j2sdk6.0-sun/bin but
that setting is not in effect at the time your window session is started.

There's a couple of workarounds

1. Give an explicit path to Java in the menu config, for example
   /usr/lib/j2sdk6.0-sun/bin/java
2. Add a (synthetic) jinfo entry for JDK 6
   Perhaps the easiest way to do this is to install Sun Java SE 5.0
   from unstable (apt-get -t unstable sun-java5-jre) and
   examine /usr/lib/jvm/.java-1.5.0-sun.jinfo
   You may find it easiest to move the JDK 6 tree to a similar location
   # mv /usr/lib/j2sdk6.0-sun /usr/lib/jvm/java-6-sun
   And then create an appropriate jinfo file
   /usr/lib/jvm/.java-6-sun.jinfo
   And finally choose this implementation
   # update-java-alternatives --set java-6-sun
   Now /usr/bin/java will be set to point to JDK 6 (and as that is
   part of the path before your window session starts it should be
   found without trouble).

In any case, no, you should not have to set LD_LIBRARY_PATH -- it
*is* a job for the java developers!

HTH,
