The sneaky discovery you're referring to is the Class-Path: entry in the 
openjms-0.7.7-alpha-3.jar MANIFEST.MF
file. Its a standard way of describing a jar's dependencies.
See http://java.sun.com/docs/books/tutorial/deployment/jar/downman.html 
for more details.

OpenJMS is built with maven 1.0.2.
The list of jars required for clients is listed here:
