Hi:
I am working on integrating the Sandesha2 module to Tuscany web service to
support conversational web service.
Currently, I met a problem with the wsdl parsing. As the spec said (sca
assembly model 100.pdf line 916), I should add a
sca:requires="conversational" to the port type to declare it as
conversational at the web service side. But the Tuscany always complain the
following exception.
/-------------------------------------------------
Caused by:
org.apache.tuscany.sca.contribution.service.ContributionReadException:

I did an quick investigation here. The exception is reported by WSDLReader
(in package wsdl4j-1.6.2.jar).
Any ideas on this problem? Do I mis-understand the spec or something wrong
here(I am guessing WSDLReader don't understand this kind of policy
extension). My test wsdl file is attached for your reference.
Thanks for your kindly help.
