Hi all,

I'm running into problem of reinstalling J2SDK. Originally I placed it at /usr/local/java.
I removed, then reinstall it. However, this error messeage popped up:

"package j2sdk-1.4.2_04-fcs is already installed"

I have used find, whereis and slocate to look for that file. But it's no where to be found.
I have looked at a similar problem posted in this forum, but it didn't have the answer.

Could it be my profile's problem? I did an echo $PATH, and the result is:

package j2sdk-1.4.2_04-fcs is already installed

Another question is: where is the best place to install JAVA so that everyone else can use?
Is it /usr/local or /usr?

Thank you all for your time and assistance,

Happy

It doesn't really matter if you install it to /usr/local or /usr. I prefer installing all Java-related software and documentation under /usr/local/java.

In order to make java easily accessible to the users you must add the bin subdirectory to your PATH variable. So if you have Java installed to /usr/local/java/j2sdk-1.4.2.04 you could add this line to your /etc/profile:
export PATH=$PATH:/usr/local/java/j2sdk-1.4.2.04/bin
You may also need to make use of the $JAVA_HOME and $CLASSPATH environment if Java apps still doesn't work. Read the Java docs for info on how to do this.

Oh, and as for the package not installing - according to rpm it is still installed since you didn't uninstall the rpm.

You can grab the j2sdk self-extracting "bin" package over at http://java.sun.com if the rpm is giving you a headache.

Hi there,

Thank you for replying to my post.
I just can's seem to resolve this problem. I have tried ./j2sdk1.4.* and rpm -iv j2sdk*.rpm. But the "package j2sdk-1.4.2_04-fcs is already installed" keeps popping up.

I logged out and logged back in as root...then run "echo $PATH" ...and found this :

"/usr/local/java/j2sdk1.4.2_04/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin :/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:./"

/usr/local/java/j2sdk1.4.2_04/bin: is still in my PATH. Does this cause any problem since i removed j2sdk from /usr/java/j2sdk* ?

How do I remove it from PATH?
and how do I resoved the "package j2sdk-1.4.2_04-fcs is already installed" ?

Thank you for your time and assistance again...

The thing is, rpm thinks the package is installed since it says so in its database. Perhaps it's possible to "upgrade" using rpm -Uvh filename.rpm? I haven't used rpm-based distros in a while so I realize I'm not too much of help to you.

Perhaps you should direct your query to the distribution-specific subforum here that suits your installation.

The $PATH variable is most likely set in /etc/profile but it could be somewhere else too (/etc/sysconfig rings a bell?). But no, it doesn't actually hurt to have a non-existing directory in your $PATH, it's just a bit annoying.
