    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    Look in /usr/java. All the installed versions are there. The 'default' entry is a link to the one currently being used by default (naturally). The 'latest' entry is a link to the last version installed. Note that you can have a number of versions installed, so applications that are dependent upon deprecated ones can still work.

    The which command may also help you out:

    Code:
    [user@host home]$ which java
/usr/bin/java

    Except that in the case of RHEL/CentOS that is just a link to /usr/java/default/bin/java, and /usr/java/default is a link to the actual jre or jdk installation directory.

    No luck

    I reinstalled java in the /usr/java directory like Sun requests. I have scoured in /usr/java/jre1.6.0_13 and I have no luck finding the jre program. I thought it was /usr/java/jre1.6.0_13/bin/java. I thought it was /usr/java/jre1.6.0_13/bin/jexec. No luck. Maybe it is the script that I'm pulling it from that has a problem. What do you think?

    Well, you could use the 'find' command to search the /usr/java subdirectories.
    Code:
    find /usr/java -type f -name 'java' -print

    I was able to find java, but the script I am running is having file not found exception errors. At least, I found the Java runtime. Thanks, matonb and Rubberman.
