Hello everyone,
By using Woden, I tried to write a simple class reading WSDL files with a
given filename into a Woden WSDL20 Description (more or less by following
the example given in the release notes...)
However, when invoking the class (code below), I get a
java.lang.AbstractMethodError (see below the source code). After some Google
research, I tried to assure that I will only load the required Xerces
version, etc - yet, I still get the error.
Any hint on how to resolve this?
Any help will be highly appreciated.
Thanks in advance & kind regards,
Stefan Thanheiser
