Fedora 7下屏蔽gcj(英文)

Download and Extract
1，Get the latest version from Java.com.
Make sure you get the Linux (self-extracting file) and NOT the RPM!

2，Open a terminal and become root, then move the file you downloaded into /opt

3，Execute the file.
sh jre*.bin

4，Read the EULA and type “yes” if you agree to it

Setup Java Systemwide
1，Run this command as root in the terminal window:
vi/etc/profile.d/java.sh

2，Insert these lines:
export J2RE_HOME=/opt/jre1.6.0_01
export PATH=$J2RE_HOME/bin:$PATH

3，Run these commands:
#source /etc/profile.d/java.sh
#/usr/sbin/alternatives --install /usr/bin/java java /opt/jre1.6.0_01/bin/java 2
#/usr/sbin/alternatives --config java

4，Type “2″ then “Enter”.

So much for this.
