I was able to successfully package the files in the 2 JARs from OpenJUMP's
latest nightly build into a single JAR and execute it with a modified batch
file. I was not able to get the single JAR to execute when it included a
manifest file that designated the main class. I'll have to look into that.
This makes me suspect that I'm having a problem with Eclipse, or that
somehow I've messed up the source in my Eclipse Project. I will [1] update
my project with the latest code from the CVS repository. [2] Drink several
cold bottles of beer. [3] Report back to the list with my findings.
On a side note, it appears that OpenJUMP will run fine with a single JAR
file for the program and a batch script. If there is no good reason to have
2 JARS, why keep them?

The good news is that I just dowloaded the nightly build of OpenJUMP and
it sucessfully executed using the batch file.
The bad news is that this means I don't know how to properly build a JAR
file. :[
I'm going to extract the contents of the JAR from the nightly build and
see if I can repackage it into a JAR that executes. Perhaps this will help
me determine what my problem is.
