(I am in a different time zone.) Hello, Below are the steps I'm using to install the Java 5 SDK that is from Sun. I hope this helps you. This has worked for me every time. Anyway, below are the steps I did to set up the Java development environment: 1. Download the latest Java 5 SDK from http://java.sun.com (35 MB) 2. $sudo rpm -Uvh jdk-1_5_0_04-linux-i586.rpm 3. # ln -sf /usr/java/jdk1.5.0_04 /usr/local/java We do this so that if a new Java version comes out, we can install the RPM and only change the directory that the symlink points to. It's more upgrade-friendly this way. 4. Edit /etc/profile and add the following lines: export JAVA_HOME=/usr/local/java export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar export PATH=$JAVA_HOME/bin:$PATH The jikes compiler requires that the CLASSPATH be set to the correct directory. The "." entry lets us include classes which are in the same directory. The last one adds our directory to the path. You can also opt to put these lines in your .bashrc. But I prefer it this way so that the changes are system-wide. 5. # alternatives --install /usr/bin/java java /usr/local/java/bin/java 3 The default java compiler is gcj. We use the alternatives system to install our new Java setup without overwriting the previous gcj settings. If we want to use gcj, we can easily switch to that one by running # alternatives --config java 6. # alternatives --config java (then choose our new Java command) Choose the one that is on the /usr/local/java directory. -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.
