If you are doing a default x86 Sun JDK install, you will find the

symlinks pointing to the Java6 directory.
You could add /usr/java/default/bin to your path (either by modifying
/etc/profile file, or in any other file that you use to setup your
environment)
Now, you should be able to run whatever command that you wanted to
run:
java -jar XYZ.jar

Hi Rogue, I would never guessed the above. Turns out you need to be
using a root login.
No, you should _not_ have to be root. In fact, you should try quite hard
to avoid being root when not doing system administration.

see how to do it :-)
Always a good start.
Thank you so much. I was sure that having no /usr/bin/jar meant I
did something wrong. But the new stuff takes new ways. Thanks a lot!
The other thing you should bear in mind is that "jar" is a tool like
"ar",
"tar" or "zip" - it constructs, inspects or unpacks ".jar" files.
To _run_ a java program you want the "java" command.
Usually a Java app is distributed as a jar file, an archive
containing the
program, and the command "java -jar foo.jar" is used to run it.
You still need "java" in your $PATH, or to invoke "java" explicitly (eg
"/usr/java/bin/java") if it is not in your $PATH. Usually it is
desirable to
adjust your $PATH you include this stuff, saving painful long paths
later.
Both "java" and "jar" have manual pages, quite good ones. If java in
installed out of the "vendor" area (here "vendor" means redhat/fedora
and "/usr/bin" is part of their area - that they expect a free hand
in), you will need to adjust your $MANPATH to include the "..../man"
directory of wherever the java package is installed, much as you have to
adjust $PATH to include the "..../bin" directory to run "java" without
using the full path of the command.
Cheers,
OK I am finding this at /usr/java/:
[root@k5di ~]# ls /usr/java
default jre1.6.0_03 latest
Now default and /usr/java/jrel.6.0_03/ are identical and have this:
[root@k5di ~]# ls /usr/java/jre1.6.0_03/
bin javaws LICENSE plugin THIRDPARTYLICENSEREADME.txt
COPYRIGHT lib man README Welcome.html
[root@k5di ~]#
My experiance to date is that using $ java -jar filename.jar works
but other problems crop up. Also I have no man java. So it is not in
the searchpath for man packages. How do I fix that?

Well I tried to get an earlier version of jedit to run and sure
enough a NEW JAVA problem. From the error notice that says this:
[karl@k5di ~]$ jedit
GC Warning: Out of Memory! Returning NIL!
Exception in thread "main" GC Warning: Out of Memory! Returning NIL!
java.lang.NoClassDefFoundError: org.gjt.sp.jedit.jEdit
*** Got java.lang.OutOfMemoryError while trying to print stack trace.
[karl@k5di ~]$
I can't tell if it is a problem with jedit or my version 6 java. I don't
know what GC is and org.gjt.sp.jedit.jedit is greek to me.
