install openjdk uia standard centos 5.x rpms, install Sun Java to 
/usr/java/jdk-whatever via the Sun tarball.

if you put /usr/java/jdk-whatever/bin first in the path, you'll be using 
the Sun java.  if you take it out of the path, you will be using the 
default distribution openjdk.


On som eof our development systems we have 3-4 different versions of Sun 
java we manage this way.
