Sun Microsystems Java SE JDK
The Java programming language was initially developed by Sun Microsystems. Its Java JDKs are usually available for Linux, Solaris, and Windows. You can download them at http://java.sun.com/javase/downloads.jsp.
Sun offers at least a couple of packaging choices for each version of Java, for each

Once it is installed, set JAVA_HOME and PATH like this:
#JAVA_HOME=/usr/java/jdk1.6.0_01#export JAVA_HOME#PATH=$JAVA_HOME/bin:$PATH#export PATH
Then, check to make sure your java executable points to the JDK you just installed:
# which java
/usr/java/jdk1.6.0_01/bin/javaHere's how the HotSpot JVM identified itself on one of our Linux computers:
