OK I am finding this at /usr/java/:
[root@k5di ~]# ls /usr/java
default jre1.6.0_03 latest
Now default
^^^^^^^
I am not sure what you mean at this ^^^ point.
Unless "default" is a symbolic link that points at "jre1.6.0_03".
The "ls -l /usr/java/" command will show this.
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?
As mentioned, you want to update your $PATH and $MANPATH.
Looking at your output above I would suggest running these shell
commands:
PATH=/usr/java/jre1.6.0_03/bin:$PATH
MANPATH=/usr/java/jre1.6.0_03/man:$MANPATH
export PATH MANPATH
The other thing that java tends to like is the $JAVA_HOME variable.
You might usefull do this instead:
JAVA_HOME=/usr/java/jre1.6.0_03
PATH=$JAVA_HOME/bin:$PATH
MANPATH=$JAVA_HOME/man:$MANPATH
export JAVA_HOME PATH MANPATH
The see if "man java" produces a manual page. (Be warning, it's a very
long manual page!) Also see if "java -jar filename.jar" now behaves
better.
