Java problems

[Stefan Gsundbrunn]

Hi,

I tried to start with java -jar a *.jar file. With a result I really
cannot understand. Could anybody please advice, what to do??

Thanks in advance!

Stefan

This script is a placeholder for the /usr/bin/java
master link required by jpackage.org conventions.  libgcj's
rmiregistry, rmic and jar tools are now slave symlinks to these
masters, and are managed by the alternatives(8) system.

This change was necessary because the rmiregistry, rmic and jar tools
installed by previous versions of libgcj conflicted with symlinks
installed by jpackage.org JVM packages.
