Re: Problems installing Eclipse on Linux

we would like to run Eclipse on a Linux server system. After downloading
and unzipping, the program is supposed to start just by running the
binary. This will not work with the following error message:

Warning: -XX:MaxPermSize=256m not understood. Ignoring.
Warning: -Xms40m not understood. Ignoring.
Warning: -Xmx256m not understood. Ignoring.
Warning: -jar not understood. Ignoring.

what should I do to make it run properly? My searches indicated that
there is something wrong with our version of Java, but downloading the
Netbeans bundle with JDK did not help. Thanks in advance.
