#213 ZSI.generate.Wsdl2PythonError: must specify part for doc/lit


When trying to generate the server stub using wsdl2py on a wsdl file automatically generated by axis2, I get this error:
$ wsdl2py -blu http://localhost:8080/axis2/services/HelloServer?wsdl
Traceback (most recent call last):

ZSI.generate.Wsdl2PythonError: must specify part for doc/lit msg

One of the server function takes no parameter and apparently this is a problem because the wsdl generated by axis is like this:
<wsdl:message name="HelloRequest"/>

and wsdl2py expects a <wsdl:part ...> in it.

I think ZSI should handle this better and not crash.

Note: I tried both ZSI2.0 and ZSI svn (2.1?) and they both crashed the same way.

    I'm having the same problem with axis.

    Is there a way to avoid/solve the issue?

    Here is the offending entity:

    <wsdl:message name="HelloRequest"/>

    From http://www.ws-i.org/Profiles/BasicProfile-1.0-2004-04-16.html#WSDLMSGS

    """"Use of wsdl:message elements with zero parts is permitted in Document styles to permit operations that can send or receive messages with empty soap:Bodys.""""

    Basically what needs to be done here is an empty <soap:Body> is sent...

    Now only ONE operation should be able to specify an message w/o a part ( for doc/lit ), because the wire representation of each operation MUST be unique.

    I just added a unittest into svn. These tests are approximate expected/correct behavior.

    $ cd zsi/test/wsdl2py
    $ python test_NoMessagePart.py local
    $ python test_NoMessagePart.py dispatch
