Installing openjdk over Sun Java 6 stops printing of PDF files

[Larry Alkoff]

I was using Sun Jave 6 but changed to openjdk because Sun Java 6 would 
not print using a program called Moneydance.

Openjdk prints just fine in Moneydance but will not print a PDF file as 
Sun Java did.

I think Sun Java is no longer active on my machine since
/usr/bin/java -version
says
   java version "1.6.0_0"
   OpenJDK  Runtime Environment (build 1.6.0_0-b11)
   OpenJDK Server VM (build 1.6.0_0-b11, mixed mode)

How can I resolve this?

Using Kubuntu Linux 10.04-1.
