It depends on which Java you have installed.  Try this:

 $ alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java
   2           /usr/lib/jvm/jre-1.5.0-gcj/bin/java

If you're on x86, select openjdk.  If you don't see openjdk,

yum install java-1.6.0-openjdk-devel
