Globally Configure Java

[linux_trojan]

I have java installed, but I dont have it configure. I would like to configure it globally for all applications. In the past,that has involved setting some $PATH in .rcbash or .profile. Recently I saw something on the internet about java.sh. Its confusing. Is there some quick and easy way to do this?

No need to change $PATH. Just make a symbolic link to the java executable in /usr/bin (which is already in $PATH). As the root user, execute the following command in a terminal:

 

ln -s /usr/java/jre1.5.0_04/bin/java /usr/bin/java

 

Note that the jre1.5.0_04 in the command above may be different for you - the latest version is 06, I believe. Use the correct directory reference based on your install.

I guess this command is not completely global, coz java doesnt work in Firefox. I have to do another sym link to the mozilla plugin folders? Back around 2002, I remember you could just do a $PATH configuration in .rcbash and bingo that was it. Java worked everywhere. Are the good ole days over?

Firefox uses a plugin ( namely libjavaplugin.oji.so ) and not a java binary. But you are right - the above method isn't 'global", some things like Java web start won't work, unless of course you softlink all java binaries to a system path, which does not make much sense.

The best method is indeed setting the java binaries path, either to say ~.bash_profile (for single user system), or for global application to some other startup script ( /etc/rc.sysinit or /etc/rc.local or...).

single user mode would be good, actually that is the method to which I was referring. I remember the file .profile was one to edit. These days I cant find .profile or .bashrc. Even if I could, the way to set the path is probably diferent too. If there is a way to set it for single user I would be interested in knowing.

.bash_profile is at your user's directory (hidden).

In Mandriva 2006, there is no .bash_profile. All I see is .bash_history. Even if there were, how would the $PATH look?

Not sure why you have no ~/.bash_profile or ~/.bashrc, but I don't know of any reason you couldn't create them. On my much-modified 10.1 box my ~/.bash_profile is like this:

 

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
       . ~/.bashrc
fi

export BASH_ENV=$HOME/.bashrc

...which as you can see aims to ~/.bashrc, which looks like this:

 

# .bashrc

PATH=/bin:/usr/bin:/usr/X11R6/bin:/usr/ucb:/usr/games:/usr/local/bin:

# Source global definitions
if [ -r /etc/bashrc ]; then
       . /etc/bashrc
fi

export NNTPSERVER=news-server.kc.rr.com

Does that help you out a little?
