Small question...

[Drakain Zeil]

I would have used google normaly, but it's too genaric of a search for me to get what I'd want.

 

I installed Java, but I get this error when installing somthing that needs it:

Preparing to install...

Extracting the installation resources from the installer archive...

Configuring the installer for this system's environment...

No Java virtual machine could be found from your PATH

environment variable.  You must install a VM prior to

running this program.

 

What I want to know is, what is the "PATH" and how do I set up an installation of java to get this working?

You can do it two different ways. My java is in /usr/java/j2re1.4.2_03/bin, so I can make a symlink to it in /usr/bin (as root, in a console):

 

ln -s /usr/java/j2re1.4.2_03/bin/java /usr/bin/java

ln -s /usr/java/j2re1.4.2_03/bin/java_vm /usr/bin/java_vm

 

Or I could add /usr/java/j2re1.4.2_03/bin to my PATH. In /etc/profile, I could add this:

if ! echo ${PATH} |grep -q /usr/java/j2re1.4.2_03/bin; then
   PATH="$PATH:/usr/java/j2re1.4.2_03/bin"
fi

Ah, thanks. :D

if ! echo ${PATH} |grep -q /usr/java/j2re1.4.2_03/bin; then
   PATH="$PATH:/usr/java/j2re1.4.2_03/bin"
fi

In addition, some programs need the JAVA_HOME environment variable to be set before they will work. You may want to add this to your /etc/profile as well.

 

JAVA_HOME=/usr/java/j2re1.4.2_03

export JAVA_HOME

 

Notice that the JAVA_HOME variable does not include the /bin at the end of the path.
