I have a simple class that I am exposing as a Web Service and calling from .NET:
package com.mypackage;
public class Greeting {
public String sayHello(String caller) {
return "Axis says hello to " + caller;
}
}
I use a simple deployment:
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="Greeting" provider="java:RPC" use="literal">
<requestFlow><handler type="soapmonitor"/></requestFlow>
<responseFlow><handler type="soapmonitor"/></responseFlow>
<parameter name="allowedMethods" value="sayHello"/>
<parameter name="className" value="com.mypackage.Greeting"/>
</service>
</deployment>
If I call deploy this in Axis1.1RC1 (WSDL below) and call it from a C# program running in VS.NET, I see the following in the Soap Monitor:
Request:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<sayHello xmlns="http://localhost:9080/WS1/services/Greeting">
<caller>.NET</caller>
</sayHello>
</soap:Body>
</soap:Envelope>
Response:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<sayHelloResponse xmlns="http://localhost:9080/WS1/services/Greeting">
<sayHelloReturn xmlns="">Axis says hello to .NET</sayHelloReturn>
</sayHelloResponse>
</soapenv:Body>
</soapenv:Envelope>
But the .NET Proxy doesn't seem to be able to find the output message and return null as the result of the call
If I deploy this in Axis 1.1RC2 (WSDL below) when I try to add a reference to the service in my VS.NET project, it fails with the message:
Key cannot be null. Parameter name: key
Now I can get around this by providing more info in my deployment:
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="Greeting" provider="java:RPC" use="literal">
<requestFlow><handler type="soapmonitor"/></requestFlow>
<responseFlow><handler type="soapmonitor"/></responseFlow>
<operation name="sayHello" qname="ns1:sayHello" returnQName="ns1:sayHelloResult" returnType="xsd:string" xmlns:ns1="http://mypackage.com/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<parameter qname="ns1:caller" type="xsd:string"/>
</operation>
<parameter name="wsdlTargetNamespace" value="http://mypackage.com/"/>
<parameter name="allowedMethods" value="sayHello"/>
<parameter name="className" value="com.mypackage.Greeting"/>
</service>
</deployment>
Under both RC1 and RC2, the above results in a successful call from .NET. The Response is different from the above response in 2 ways:
<sayHelloResponse xmlns="http://mypackage.com/">
<sayHelloResult>Axis says hello to .NET</sayHelloResult>
</sayHelloResponse>
It uses the specified namespace and there is no longer the xmlns="" attribute in the sayHelloResult tag.
Now the question:
Is this a bug in Axis?
Is this a bug in .NET?
Am I doing things wrong?
Or do I just expect too much?
Any thoughts would be appreciated. Thanks.
Some gory details:
