Subject WSDL2Java, MTOM, and ADB binding error (July 13 snapshot)
Date Thu, 13 Jul 2006 15:43:41 GMT
Hi everyone,

First of all, a big thanks for the project team for a great product! I'm new
to WS and decided to start with Axis2 and generate code from WSDL. I'm
developing a service which utilizes MTOM for transferring images. After
finally (hopefully) figuring out how to do this in WSDL, I'm trying to
generate code for it. Since my schema isn't all that complicated I gave ADB
a shot. Release 1.0 generated code without errors, but it didn't generate
any data holding classes, leaving me with OMElements in the skeleton. From
examples I saw that this wasn't the way it should be. So I tried the latest
nightly build (July 13), but WSDL2Java died with the following stack trace.
XMLBeans binding worked perfectly. Now, I know ADB is limited, but it should
be able to handle MTOM, right? Please find my (simplified) WSDL below.

Juho
