Hi Brian,
I changed the file RetrievalSetup.java to get the stacktrace.
So I got a new cas-pushpull-0.4.jar after rebuilt it.
The following is a message including the stacktrace with information
about excpetion propation.
SEVERE: Failed to finish downloading per property files
/home/yhkang/oodt/cas-pushpull/etc/examples/DirStructXmlParserFiles/RTG_SST.xml
