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.

build-classpath

BUILD-CLASSPATH(1)						Java Packages Tools						BUILD-CLASSPATH(1)

NAME

       build-classpath - build a Java CLASSPATH

SYNOPSIS

       build-classpath JAR|artifact-coordinates [JAR|artifact-coordinates ...]

DESCRIPTION

       Small utility to build a Java CLASSPATH with the named JARs or Maven artifact coordinates. Artifact coordinates specify Maven artifact and
       are in format groupId:artifactId[:extension[:classifier]]:version. If extension is omitted then "jar" is used. If classifier is omitted
       then empty classifier is used. For more information see XMvn Configuration Reference. The CLASSPATH is returned to standard output.

EXAMPLES

       build-classpath junit xerces-j2 wsdl4j - this will return a string to standard out that is a valid CLASSPATH containing junit, xerces-j2,
       and wsdl4j JARs.

       build-classpath log4j:log4j org.apache.commons:commons-io - this will return a string to standard out that is a valid CLASSPATH containing
       log4j and commons-io JARs.

       build-classpath com.google.inject:guice::no_aop: - this will return a string to standard out that is a valid CLASSPATH containing
       google-guice JAR with classifier no_aop.
