FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Ubuntu Linux 5.10

EXTRA RELEVANT SYSTEM CONFIGURATION :
Using a remote CUPS server. The CUPS_SERVER variable is set to point to it.

A DESCRIPTION OF THE PROBLEM :
I can't print using a remote CUPS server. It seems Java fails to communicate using IPP, so it tries to fallback to "lpr" command. However, the path is hardcoded to "usr/bin/lpr", but in my system it's located in "usr/local/bin/lpr".


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try to print using a remote CUPS server, in a system where lpr is installed under /usr/local/bin. You always get this error.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The job should be sent to the printer.
ACTUAL -
An exception.
