Exception in thread "main" java.lang.ExceptionInInitializerError

[JG]

I'm running Fedora Core 4. I successfully installed eclipse via rpm
repository / yum, however I am unable to get java running properly.

This is the error:

./KitchenSink-shell

I'm guessing that perhaps I don't have the JEE 1.4 SDK installed
properly, but when I run the JEE installer, it hangs on:

./j2eesdk-1_4_03-linux.bin -console
.. blah blah ..
Installation Directory [/opt/SUNWappserver] {"<" goes back, "!" exits}:
<ENTER>
<HANG>

Any help is appreciated!

If you installed eclipse with yum you are probably using the native
version(compiled with gcj for linux). Try downloading the regular one
from eclipse.org and install the jre.

Before I started installing anything, I had a successful running
jre1.5.0_06 installation. I received this error under that condition -
is that to be expected as well?

[musachy]

Sorry for my previous message, your problem has nothing to do with
eclipse. When you type java -version on the shell, what do you get? I
think your "java" is pointing to gcj's "java" executable, instead of
sun's implementation. If that is the case you can delete "java" from
/usr/bin and create a soft link to sun's "java" executable.

[JG]

This is indeed the case, and I thank you.

I have also found that the J2EE 1.4 SDK installer does work, but there
is a VERY long delay after it creates /opt/blah..

Thanks again for your help. I'll complete the installation tomorrow
and hopefully everything will work!

Is there no way to run GWT with the GNU Java that comes with FC5?
