Hello,
I am encountering what I expect to be a simple error, but my lack of
experience with WSDL is holding me back.
Basically, I am trying to expose an asynchronous "UpdateRequest"
operation on the wsn-producer tutorial that takes a String as a
parameter and returns void. i.e. In MyCapability.java, I want to
implement a method with the following signature: public void
UpdateRequest(String ...)
What I have added to the sample wsn-producer.wsdl (attached) thus far:
<!-- Block 1 -->
<wsdl:message name="UpdateRequestMessage">
<wsdl:part name="UpdateRequest"
type="xsd:string">
</wsdl:part>
</wsdl:message>
<wsdl:message name="UpdateResponseMessage">
<wsdl:part name="Void"
type="xsd:anyType">
</wsdl:part>
</wsdl:message>
<!-- End Block 1 -->
<!-- Block 2 -->
<wsdl:portType name="WsResourcePortType"
.....
<wsdl:operation name="UpdateRequest">
<wsdl:input wsa:Action="http://ws.apache.org/muse/test/wsrf";
name="UpdateRequestMessage"
message="tns:UpdateRequestMessage" />
<wsdl:output wsa:Action="http://ws.apache.org/muse/test/wsrf";
name="UpdateResponseMessage"
message="tns:UpdateResponseMessage" />
</wsdl:operation>
.....
</wsdl:portType>
<!-- End Block 2 -->
<!-- Block 3 -->
<wsdl:binding name="WsResourceBinding"
.....
<wsdl:operation name="UpdateRequest">
<wsdl-soap:operation soapAction="UpdateRequest" />
<wsdl:input name="UpdateRequestMessage">
<wsdl-soap:body use="encoded" encodingStyle="
http://schemas.xmlsoap.org/soap/encoding/
<http://schemas.xmlsoap.org/soap/encoding/> " />
</wsdl:input>
<wsdl:output name="UpdateResponseMessage">
<wsdl-soap:body use="encoded" encodingStyle="
http://schemas.xmlsoap.org/soap/encoding/
<http://schemas.xmlsoap.org/soap/encoding/> " />
</wsdl:output>
</wsdl:operation>
....
</wsdl:binding>
<!-- End Block 3 -->
The command that I am running is: wsdl2java -wsdl
.\wsdl\wsn-producer.wsdl -verbose (called from the base of my project
directory with subdirectory wsdl which contains the sample wsdl and all
of the imported wsdl's and xsd's)
The error that I am receiving is:
C:\Documents and Settings\gradybr\Desktop\ExposedUpdate>wsdl2java -wsdl
.\wsdl\wsn-producer.wsdl -verbose
SEVERE: [ID = 'CodeGenFailed'] Code generation failed, see the exception
information below.
An exception was caught: [ID = 'NullTypeQName'] The QName describing the
type declaration is null.
The exception generated the following stacktrace:

describing thetype declaration is null.

I am new to Muse and Web Services in general. I have followed the
tutorial and have the wsn-producer (beginning with the WSDL) example up
and running correctly.
Thanks for any help,
Brendan Grady
