[WSDL Analyzer] No operation can be associated with the bind

[daneel]

Hi,

I'm a beginner with web services and I'm trying to test the WSDL Soap analyzer function of OxygenXML/Eclipse to verify a very simple WSDL file :

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<wsdl:definitions targetNamespace="http://www.larim.polymtl.ca/myapp/webservice" 

    xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"

    xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" 

    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 

    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

    xmlns:xs="http://www.w3.org/2001/XMLSchema" 

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:ec="http://localhost:8080/myapp/webservice/Echo"

    xmlns:simple="http://localhost:8080/myapp/ns/simple">

    <!-- Type definitions -->

    <wsdl:types>

        <xs:schema targetNamespace="http://localhost:8080/myapp/ns/simple">

            <xs:element name="echo" type="xs:string"/>

        </xs:schema>

    </wsdl:types>

    

    <!-- Message definitions -->

    <wsdl:message name="EchoRequest">

        <wsdl:part name="echo" element="simple:echo"/>

    </wsdl:message>

    <wsdl:message name="EchoResponse">

        <wsdl:part name="result" element="simple:echo"/>

    </wsdl:message>

    

    <!-- Port type definitions -->

    <wsdl:portType name="EchoPortType">

        <wsdl:operation name="echo">

            <wsdl:input message="ec:EchoRequest"/>

            <wsdl:output message="ec:EchoResponse"/>

        </wsdl:operation>

    </wsdl:portType>

    

    <!-- Binding definitions -->

    <wsdl:binding name="EchoSOAPBinding" type="ec:EchoPortType">

        <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>

        <wsdl:operation name="echo">

            <soap:operation soapAction="http://localhost:8080/myapp/admin/webservice/Echo/echo"/>

            <wsdl:input>

                <soap:body use="literal"/>

            </wsdl:input>

            <wsdl:output>

                <soap:body use="literal"/>

            </wsdl:output>

        </wsdl:operation>

    </wsdl:binding>

    

    <wsdl:service name="Echo">

        <wsdl:port name="Echo" binding="ec:EchoSOAPBinding">

            <soap:address location="http://localhost:8080/myapp/admin/webservice/Echo"/>

        </wsdl:port>

    </wsdl:service>

    

</wsdl:definitions>

The problem is that I don't manage to access the analyzer as I always get an error dialog box with the following message :

No operation can be associated with the binding:
{http://localhost:8080/myapp/admin/webse ... OAPBinding

Does anyone know how to decypher this enigmatic message ? Can you help me to find my mistake in my WSDL file ?

Thx in advance.

Hi,

The <wsdl:service> specifies a <wsdl:port> which points to a certain binding:

Code: Select all

 <wsdl:port name="Echo" binding="ec:EchoSOAPBinding"> 

The binding being described in the same document has the target namespace http://www.larim.polymtl.ca/myapp/webservice but the port tries to refer it with the proxy "ec" which is from target namespace http://localhost:8080/myapp/webservice/Echo.

So the error above specifies that there can be found no binding called EchoSOAPBinding from target namespace http://localhost:8080/myapp/admin/webservice/Echo

The solution is quite simple: the URLs to which the "targetNamespace" and the "xmlns:ec" attributes in the <wsdl:definitions> tag point to must be identical.


Hope this helps.
Regards, Radu.

Thx a lot Radu... it's precisely the problem.
