- To check: Run java -version on the command line
- If not correct, download the J2SE SDK from:
- Sakai 2.7.x or less: http://java.sun.com/j2se/1.5.0/download.jsp
- Sakai 2.8 or higher: http://www.oracle.com/technetwork/java/javase/downloads/index.html
- Mac OS X users will have Java 1.5 or 1.6 by default
- Install it (the SDK) to /opt/java
- Note: Install the JRE to a different directory (probably the default, especially under windows) or you will have problems
- Set environment variable: JAVA_HOME=/opt/java
- Mac users: JAVA_HOME=/Library/Java/Home
- Windows users default: JAVA_HOME=C:\j2sdk1.5.0_xx j2sdkXXX (where "xxXXX" is the minor version - for example "j2sdk1.5.0_0611")
- Add $JAVA_HOME/bin to PATH
- Set environment variable: JAVA_OPTS for tomcat in the tomcat/bin/setenv file (see Install Tomcat 5.5)
No Format JAVA_OPTS='-server -Xms384m -Xmx768m -XX:NewSize=192mXmx964m -XX:MaxNewSize=384m -XX:PermSize=96m -XX:MaxPermSize=160m172m -Djava.awt.headless=true'
