sun-java5-jre installed but not recognized

["CN Liou" <cnliou9@fastmail.fm>]

Hi!

I just installed package sun-java5-jre from unstable but none of the  
following directories is recognized by OpenOffice:

/usr/lib/jvm/
/usr/lib/jvm/java-1.5.0-sun-1.5.0.07
/usr/lib/jvm/java-1.5.0-sun-1.5.0.07/jre

OpenOffice complains: "The folder you selected does not contain a Java  
runtime environment. Please select a different folder"

Exactly where is java runtime environment after the installation?

Thank you in advance!
