[fw-general] Cannot consume SOAP Service

[Jan Pieper]

Hi guys,

I created a small soap service with Zend_Soap_Server and Zend_Soap_AutoDiscover
but I cannot consume its data via a java soap client. I tried it all the day but
it won´t work.

----- SNIP -----

class MyFooService
{
    /**
     * @return string
     */
    public function getStaticString() {
        return 'Hello World';
    }
}

----- SNAP -----

It is accessable (for me!) via http://jason/Laboratory/JMS/service.php which is
the service and http://jason/Laboratory/JMS/service.php?wsdl which will show
wsdl definition. The created wsdl definition looks like this:

----- SNIP -----

<?xml version="1.0"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/";
xmlns:tns="http://jason/Laboratory/JMS/service.php";
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/";

    name="MyFooService"

    <portType name="MyFooServicePort">
        <operation name="getStaticString">
            <input message="tns:getStaticStringRequest" />
            <output message="tns:getStaticStringResponse" />
        </operation>
    </portType>
    <binding name="MyFooServiceBinding" type="tns:MyFooServicePort">
        <soap:binding style="rpc"
transport="http://schemas.xmlsoap.org/soap/http"; />
        <operation name="getStaticString">
            <soap:operation

soapAction="http://jason/Laboratory/JMS/service.php#getStaticString"; />
            <input>
                <soap:body use="literal"
                    namespace="http://jason/Laboratory/JMS/service.php"; />
            </input>
            <output>
                <soap:body use="literal"
                    namespace="http://jason/Laboratory/JMS/service.php"; />
            </output>
        </operation>
    </binding>
    <service name="MyFooServiceService">
        <port name="MyFooServicePort" binding="tns:MyFooServiceBinding">
            <soap:address location="http://jason/Laboratory/JMS/service.php"; />
        </port>
    </service>
    <message name="getStaticStringRequest" />
    <message name="getStaticStringResponse">
        <part name="getStaticStringReturn" type="xsd:string" />
    </message>
</definitions>

As you can see I do not use Zend_Soap_AutoDiscover in its original version (see
attached MyAutoDiscover.diff, could not extend and use my own class because I
need access to private class properties). I needed to change <soap:body
use="encoded" encodingStyle="..." /> to <soap:body use="literal" namespace="..."
/> because wsimport (small tool included in jdk) cannot handle "encoded". So I
used following command to create java classes from wsdl definiton:

# wsimport -keep http://jason/Laboratory/JMS/service.php?wsdl

So I got this two java classes:

# jason.laboratory.jms.service.MyFooServicePort.java
# jason.laboratory.jms.service.MyFooServiceService.java

After that I created a soap client using these classes (jdk1.6.0_10):

----- SNIP -----

package jason.laboratory.jms.myfooclient;

import jason.laboratory.jms.service.*;

public class MyFooClient
{
    /**
     * @param args
     */
    public static void main(String[] args)
    {
        MyFooServiceService mfss = new MyFooServiceService();
        MyFooServicePort    mfsp = mfss.getMyFooServicePort();
        String result            = mfsp.getStaticString();

        if (result != null) {
            System.out.println("Result: " + result);
        } else {
            System.out.println("Result is NULL");
        }
    }
}

----- SNAP -----

I expected "Result: Hello World" but I always get "Result is NULL".
Zend_Soap_Client has no problems consuming the service.

It looks like an java problem, but we also tested the same soap server using a
Microsoft Dynamics AX soap client and got the same result. Okay we do not get
"NULL" as return value from service, the Microsoft soap client shows "1" as 
result.

So I am searching for a solution how to get it working. I am absolutly clueless
why I do not get the correct result. Is there someone who can verify or solve my
problem? :-)

If there are any questions or if there are more information needed, please ask!
If needed I can upload my sources.
