Ambigues Webmethods?

Hi,

I have 3 operations A, B, C, with an empty parameterlist.
Whichever Webmethod I call, at the serverside always the same webmethod is called.
How can I solve this?

Here are parts of my WSDL from which I generate my classes:


		<element name="ArrayOfCustomers">
		  <complexType>
		    <sequence>
		      <element name="Customer" minOccurs="0" maxOccurs="unbounded" type="tns:Customer"/>
		    </sequence>
		  </complexType>
		</element>

		<complexType name="Customer">
			<sequence>
				<element name="name" type="string"/>
				<element name="street" type="string"/>
				<element name="city" type="string"/>
			</sequence>
		</complexType>

 		<element name="ShopException" type="xsd:string"/>

		/schema>
	</types>

	<message name="CustomerRequest"/>
	<message name="CustomerResponse">
		<part name="result" element="tns:ArrayOfCustomers"/>
	</message>

	<message name="HandlerRequest"/>
	<message name="HandlerResponse">
		<part name="result" element="tns:ArrayOfHandlers"/>
	</message>

	<message name="ShopException">
		<part name="ShopException" element="tns:ShopException"/>
	</message>


	<portType name="RequestPortType">
		<operation name="getCustomers">
			<input message="tns:CustomerRequest"/>
			<output message="tns:CustomerResponse"/>
			<fault name="ShopException" message="tns:ShopException"/>
		</operation>
		<operation name="getHandlers">
			<input message="tns:HandlerRequest"/>
			<output message="tns:HandlerResponse"/>
			<fault name="ShopException" message="tns:ShopException"/>
		</operation>

the WSDL is literal/document one.

Hi Daniel,

I adjusted my WSDL according to your suggestion,
now the webservices do function as expected
Thanks you very much for the information.

Yea, this won't work.   There is nothing on the wire to indicate which method 
to call.    Basically, the soap:body is empty so we pretty much just grab one 
of the methods that will work for that.  

Technically, this wsdl is not WSI-BP compliant at all and the tools should 
probably flag it.   The request messages need to have a part that points to a 
unique element.  Example:
<element name="CustomerRequest">
   <complexType>
      <sequence/>
   </complexType>
</element>

<message name="CustomerRequest">
    <part name="parameters" element="tns:CustomerRequest"/>
</message>
