Thread Subject: Errors when launching matlab (linux)

I just installed matlab on Fedora 9. When I run it, i get
the errors below. If I just ignore the errors, everything
seems to work fine. Has anyone else experienced this?

Below is the output:

Hi Dave,

yes I have the same thing. After the suggested install of
the java runtime environment through

export MATLAB_JAVA=/usr/lib/jvm/java-6-sun-1.6.0.06/jre

what worked for other people - my matlab stopped working.
So I would happy for any sugestions.

Michael

Which distribution/version of Linux you use?
Maybe you're having problems
with any lib of your Linux OS.
