Bug Just a bit of follow up...
I had been under the impression that trouble I encountered when trying to run my Insert_data JAVA class(application or whatever) can from my shell's ENV not being set correctly. I tried everything! I set CLASSPATH and PATH in .tcshrc . In the initial C SHELL script that is called from cron, I added things like ...

setenv JAVA_HOME_R "/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Classes"
set classpath=($JAVA_HOME_R/classes.jar $JAVA_HOME_R/postgresql.jar)

You name it I tried it, but nothing worked.

What I found was it had nothing to do with setting my shells ENV (i.e. PATH CLASSPATH and such). Instead, this turned out to be entirely a JAVA side problem/solution. It was as simple as the following.

java -classpath /Users/admin/LOGS Insert_data

With the above I can run Insert_data from any directory on my machine, and I also have no trouble running/calling from cron.

Problem solved. Sorry to have gotten away from the main topic of discussion here, but I felt it might save others time, perhaps, to give a follow up.
