Question

An existing Soap WebServices is providing a WSDL file that specifies an xsd:struct.
The WebService is written in PHP.

If I try execute Wsdl2Java goal in my Java, Maven, Spring-ws, Axis Environment, it fails saying:

[INFO] [axistools:wsdl2java {execution: default}]
[INFO] about to add compile source root
[INFO] Processing wsdl: /home/foobar/workspace/com.foobar/src/main/wsdl/foobar.wsdl
Sep 17, 2012 2:29:42 AM org.apache.axis.utils.JavaUtils isAttachmentSupported
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error generating Java code from WSDL.

Embedded error: Error running Axis
Type {http://www.w3.org/2001/XMLSchema}struct is referenced but not defined.

Any ideas how to fix this?

The WSDL looks like this:

<?xml version="1.0"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://foobar.service.de/service/v2" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="Soap_Manager" targetNamespace="http://foobar.service.de/service/v2">
    <types>
        <xsd:schema targetNamespace="http://foobar.service.de/service/v2"/>
    </types>
    <portType name="Soap_ManagerPort">
        <operation name="searchFoo">

            <input message="tns:searchFooIn"/>
            <output message="tns:searchFooOut"/>

    <binding name="Soap_ManagerBinding" type="tns:Soap_ManagerPort">

        <operation name="searchFoo">
            <soap:operation soapAction="http://foobar.service.de/service/v2#searchFoo"/>
            <input>
                <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://foobar.service.de/service/v2"/>
            </input>
            <output>
                <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://foobar.service.de/service/v2"/>
            </output>
        </operation>
    </binding>
    <service name="Soap_ManagerService">
        <port name="Soap_ManagerPort" binding="tns:Soap_ManagerBinding">
            <soap:address location="http://foobar.service.de/service/v2"/>
        </port>
    </service>
    <message name="searchFooIn">
        <part name="param" type="xsd:struct"/>
    </message>
    <message name="searchFooOut">
        <part name="return" type="xsd:struct"/>
    </message>
</definitions>

Thanks for your help.

Edit 1:

This reference says:
...It's xsd:struct, which means it should be treated as an array with multiple values. Most languages render xsd:struct types as hashes with a key => value notation....

But how to do this with Apache Axis?

Edit 3:

An valid Soap Request looks like this (I get it from the doc and tested it with soap-ui):

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:emn="interface.foobar">
<soap:Header/>
<soap:Body>
    <emn:searchFoobar>
    <emn:searchParameter>
        <emn:username>xxxx</emn:username>
        <emn:password>xxxx</emn:password>
        <emn:maxHitCount>1</emn:maxHitCount>
        <emn:sorting>distance</emn:sorting>
        <emn:searchtext>example</emn:searchtext>        
    </emn:searchParameter>
    </emn:searchFoobar>
</soap:Body>
</soap:Envelope>

Unable to find required classes (javax.activation.DataHandler

You are missing a jar file from classpath. Probably activation.jar. Please look at here
