Web Service doesn't read my parameter

[Alex Parvan]

I try to send a String to my Web Service and then print it. It always prints "null". I'm developing wsdl-first using Metro.

WSDL:

    <types>
        <xsd:schema xmlns:tns="http://metrows/" xmlns:xs="http://www.w3.org/2001/XMLSchema"
                             version="1.0" targetNamespace="http://metrows/">

            <xs:element name="uploadString" type="xs:string"/>
            <xs:element name="uploadStringResponse"/>
        </xsd:schema>
    </types>

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

    <portType name="MetroWS">
        <operation name="uploadString">
            <input wsam:Action="http://metrows/MetroWS/uploadStringRequest" message="tns:uploadString" />
            <output wsam:Action="http://metrows/MetroWS/uploadStringResponse" message="tns:uploadStringResponse" />
        </operation>
    </portType>

    <binding name="MetroWSPortBinding" type="tns:MetroWS">
        <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" />
        
        <operation name="uploadString">
            <soap:operation soapAction="" />
            <input>
                <soap:body use="literal" />
            </input>
            <output>
                <soap:body use="literal" />
            </output>
        </operation>
    </binding>

(the rest of the code is not needed... i think... i wanted to make it shorter)

And this is the SOAP message being sent over:

<?xml version="1.0" ?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body><ns2:uploadString xmlns:ns2="http://metrows/">yesss</ns2:uploadString></S:Body>
</S:Envelope>

If i want to get something from the WS, it works. Something like getString.

I really really really need help with this.
Thank you in advance,
Alex.

Update:

This is the SOAP i recieve when using a get method:

<?xml version='1.0' encoding='UTF-8'?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body><ns2:getOrganisationDetailsResponse xmlns:ns2="http://metrows/">
<return>blablabla</return>
</ns2:getOrganisationDetailsResponse></S:Body></S:Envelope>

If i change <return> to something else, i have the exact problem like when uploading. Is there a tag needed to contain the request too ?

PLEASE help

Hi!
What kind of client are you using?
Have you tried to use soapUI to send requests to the web service and examine the result?
If using soapUI does not work, then there is a problem with your web service.
If soapUI does work, but your client does not work, then the problem is most likely to be the client.
Best wishes!

Thank you Ivan for your help.

I found my problem, for some reason, i have to write all elements inside a schema and import that.

    <types>   
        <xsd:schema>   
            <xsd:import namespace="http://metrows/" schemaLocation="http://localhost:8080/MetroWS/schema" />
        </xsd:schema>   
    </types>

And now it's working.

Hi.

I tried soapUI with my small "learning-project". It is able to send a request, and it gets a response (the same works with my java me client). But just as described in this thread, when it reaches the server, the arguments are somehow lost.

My wsdl looks like

<?xml version="1.0" encoding="UTF-8" ?> 
  
<definitions 
    xmlns="http://schemas.xmlsoap.org/wsdl/"

Thanks for sharing this. However, to me, it sounds strange - you should not have to do that. It should be possible to declare the message types in the <types> element of the WSDL.
An advice when writing a WSDL by hand is to use the WS-I Compliance Check tool to verify the correctness of the WSDL a step further than basic XML validation is able to do. Instructions here: http://www.soapui.org/userguide/tools/wsi.html

Please do not hijack threads - you have already posted this question in another thread and once is enough.
