I take back what I said earlier, now that I've learned how to get this
information out of the jar: The MANIFEST.MF file does contain a Main-Class
entry, and it is my Quickstart class.
My CLASSPATH environment variable now includes all the Apache Axis jars, but
running from the command line still yields the NoClassDefFoundError. What
else can I try?
