Some updates,

the /---/ is not the actual directory name, i'm using
it to keep from printing much longer directories,
also, i'm not sure if my employer would like me
writing them out to a public forum.  Sorry if I
confused anyone.  

I've made some headway on the VM issue, although I
still get the same error. We have a few instillations
of java on our servers here.  Despite having my
JAVA_HOME being set to one installation of java (java
1.3) the fact that another java installation was on my
path (java 1.2.2) caused me to run that version.

So everything _seems_ to be correct, by that I mean: 
 - when I run "env" I get that my JAVA_HOME is set to
/usr/local/webtech/installed/java-1.3.
 - when I run "java -version" I get: 
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed
mode)
 - when I run "which java" I get:
/usr/local/webtech/installed/java-1.3/jre/bin/java  
 
I've noticed a slight difference in which java is
executed though.  I have one in java-1.3/bin and
java-1.3/jre/bin, is there any difference there?

Thanks to all who are helping me work through this,
 - James
