Post "downloaded / install" I have unsuccessfully attempted to run an
interactive session - per the 'Jython Essentials' book by S. Pedroni and N.
[a] FROM CMDLINE: "F:\Jython>java -jar -classpath . F:\Jython\jython.jar"
[b] I get the following ERROR MSG: "Failed to load Main-Class manifest
Similar instructions successfully runs other java-archive-based programs,
ArgoUML for example:
F:\Jython>java -jar "C:\Program Files\Argo\argouml.jar"
"Configuration loaded from E:\Documents &
SAX Parser Factory org.apache.xerces.jaxp.SAXParserFactoryImpl will be used.
Component: ArgoUML, by: University of California, version: 0.10 ..."
The GUI installer indicated that I had the correct JVM available, and that
my Win2K version was also not a problem. Further, by comparing jython.jar
to argouml.jar, I did not the following:
 there's NO Main.class in the jython archive, and
 the ArgoUML archive 'Manifest.MF' had these directives which were NOT
in the 'jython' manifest:
[a] Main-Class: "org.argouml.application.Main"
[b] Class-Path: "xerces.jar jaxp.jar crimson.jar parser.jar xml4j.jar
nsuml.jar ocl-argo.jar gef.jar antlrall.jar log4j.jar jh.jar"
Can someone point me to some troubleshooting doc's or otherwise help me get
Jython up and running.
