JAVA_HOME points to the directory containing the Java bin, include, jre and lib subdirectories. On any installation you might have multiple JDKs. On mine: JAVA_BINDIR=/usr/lib/java/bin JAVA_HOME=/usr/lib/java JAVA_ROOT=/usr/lib/java and /usr/lib/java is symlinked to SunJava2-1.4. Note that some applications that use Java may be started from a script that may either test to see if JAVA_HOME is set or override it, which they can do without affecting other processes.
