I'm ccing this back to the list because
I'm currently incompetent with Linux...
Presumeably /usr/bin/java is a link to
/usr/lib/jvm/java-6-sun/jre/bin/java?
The point of the exercise is to validate that the java you run
is the one that TOS thinks it has installed, and that the libs
are actually usable. I don't see any listing in your jre/bin for
the JNI libs, which are conveniently unnamed in the error message:
.... Possibly TOSComm.so and getenv.so ....
It's also possible that there is a separate JRE or JDK/bin (Widows
seems to like to install TWO of the same thing just to keep any
remotely sophisticated user on h{is,er} toes).
Beyond that I am out of suggestions.
