problem with wscompile: xsd:choice not recognized and NullPointerException

[jmc]

I am having trouble with wscompile (running jwsdp 1.5).

I have validated that I can create the client-side classes by generating
from the Google wsdl as a test. When I point at the wsdl I am really
interested in for my app, though, I get a number (13) of such warnings:

-----------------------------------------------------------------
warning: unsupported XML Schema feature: "xsd:choice" in component {http://Sandl
ot/XmlWebServices/}note_edit_response, mapping it to javax.xml.soap.SOAPElement
------------------------------------------------------------------

After these warnings, I get a NullPointerException (see stack trace at end
of this posting).

I'D BE VERY THANKFUL TO ANYBODY WHO COULD TELL ME HOW TO SOLVE THESE PROBLEMS
(unsupported xsd:choice and the NullPointerException).

BACKGROUND INFO:
I don't get any generated code. I can generate the client-side stubs
successfully with a much earlier version of the jwsdp from summer of 2002,
I *think* it is version 1.0.01. However, I am not happy with these generated
client-side classes and want to try the new jwsdp.

Also, I am not the only person seeing this NullPointerException. I found
a message from someone who ran into it with jwsdp 1.4, but did not post
a solution. I don't know anything about the wsdl the person was using.
Here is the posting I saw, in case it is of interest:

Thanks in advance for any help you can afford.

Here is the stack trace I am getting:
