Re: [Jython-users] trouble with example in Jython Essentials

[Noel R. <noe...@co...>]

Your sample works for me (although I think that jdom.jar is already in
my Java classpath).  If jdom was not getting into the classpath at all
than you'd likely get an error on the import line, so I'm not
immediately sure why you are getting  an error on line five (possibly a
problem with JDOM versions?).

One thing to try to diagnose is after the import statement some lines
like this

print org.jdom.__dict__
print org.jdom.input

Those kinds of things will let you know if the package is being imported
at all.

Another thing to try would be to explicity put jdom.jar in the Java
classpath with the environment variable (or the shell script that
invokes jython).  I don't think that's the problem you are having, but
it can't hurt to try.

Let me know how this goes...
