Welcome to JavaRanch!

We have a strict policy on display names, which must be a real first and last name with a space between. Please go here and fix your display name up, pronto. Thanks, pardner!

Note that it's not the same problem at all; it's a totally different problem. Please start a new thread in our MacOS forum to ask about it.

Your problem can be fixed easily by installing the Sun JDK from java.sun.com . You're using the GNU "gcj" Java stuff which, while being an impressive achievement in its own right, isn't quite up to the task of running a stock Eclipse distribution (or, to be honest, many other things.) It comes with RedHat Linux by default. You would be doing yourself a favor by uninstalling it. But in any case, install the Sun JDK, put its "bin" directory first on your path, and Eclipse should then work fine.

i have installed the SUN JDK1.5 but when i try to get to know the version it says java 1.4.2 where as i have installed the java 1.5 update 9 and where exactly will be this GCJ so that i can uninstall it.. I am a new bie to linux so please help out.

Thank you

Hi sriya N others,

The problem is solved.. All we need to do to avoid GCJ compiler to keep quiet is just change the path.. as shown below.

#PATH=$PATH:$HOME/bin:/usr/java/jdk1.5.0_09/bin--> wont work
PATH=/usr/java/jdk1.5.0_09/bin:$PATH:$HOME--> change to this.. it works fine

make sure your SUN's JDK's path is given first .... for your note the GCJ is in the Bin so if you give SUN's JDK Bin in your path first , you would be pointing to your Installed Suns sdk instead of default GCJ.

Indeed, you'll note that I said exactly that in my original reply. Glad you got it working!
