Should I be able to access compiled Groovy classes from JRuby?

Nevermind the perversity of the question. Shouldn’t it be possible?

If Groovy compiles to bytecode, why can’t I use the class from JRuby?
In
the jar I’ve included, I can access all of the Java classes, but none of
the
Groovy classes. When I try in JIRB, it says:

NameError: cannot link Java class com.greymatter.SoapInvoker

(In case you’re wondering, I’m doing this because I can’t seem to get
soap4r
to work, while it all works easily from Groovy. If whytheluckystiff
used
SOAP, I’m sure we’d have a great solution for calling SOAP from Ruby –
with
great documentation!)

Thanks,
Lee

have you double checked that you’re requiring all the jar’s
dependencies?

i ask because just a few days ago i was experimenting with
stringtemplate in groovy but had problems in jruby. the issue was that
groovy already had stringtemplate’s antlr.jar dependency as part of its
runtime and i “forgot” to require antlr.jar when i experimented from
jruby. i got a NameError…your situation sounds a bit too familiar…

Thank you, Jon! You were right. All I had to do was require all the
jars in
~/.groovy/lib, and it all worked as expected.

Thanks for your great advice!

BTW, that’s a terribly weak error message. There really ought to be
more
information than that. At least what name caused the NameError.
