complex return types?

[St Jacques, Robert]

Hello Fellow Muse Users,

 

I've noticed that Muse's WSDL-to-Java tools don't seem to handle complex
return types in a particularly elegant way.  For example, if I define
the following type...:

 

  <wsdl:types>

    <xsd:schema elementFormDefault="qualified"
targetNamespace="http://ws.disco.xerox.com/MyService">

 

      <xsd:element name="MyMethodResponse">

        <xsd:complexType>

          <xsd:sequence>

            <xsd:element name="foo" type="xsd:string" maxOccurs="1"
minOccurs="1"/>

            <xsd:element name="bar" type="xsd:int" maxOccurs="1"
minOccurs="1"/>

          </xsd:sequence>

        </xsd:complexType>

      </xsd:element>

           

    </xsd:schema>

  </wsdl:types>

 

And then define a message as such:

 

  <wsdl:message name="MyMethodOutputMessage">

    <wsdl:part name="result" element="tns:MyMethodResponse"/>

  </wsdl:message>

 

Muse then generates a method that looks something like this:

 

public org.w3c.dom.Element myMethod() throws Exception;

 

I would have expected (hoped?) it to create a Java (bean-like, maybe)
object that mapped to my type definition.  Something like:

 

public class MyMethodResponse {

  String foo;

  int bar;

}

 

Is it the case that Muse will always convert complex return types to
this generic Element interface?

 

Thanks,

Bob

Hi,
Yes, Muse is not dependent on the data binding tool used to convert XSD
types to Java types.  Hence, a complex type input/output is identified
as an Element in your Java method signatures.

You can use data binding tools like XmlBeans or JAXB.  If you change the
capability method signatures, you need to supply/configure serializers
for each of these types.  See the following link for more info:

http://ws.apache.org/muse/docs/2.2.0/manual/architecture/deployment-desc
riptor.html#serializer

The "apache-httpd" sample has an example of this.

Hope this helps...
