Attachements and .Net: The datatype 'DataHandler' is missing

Qwzrl Wed, 22 Dec 2004 11:24:42 -0800

I'm trying to make a testapp -using my own deployment, without the axis.war- using attachements. I can't get it to work, Googled near and far, surfed high and low looking for an answer. Hopefully I'll be able to get it here. And yes, happyaxis.jsp claims attachement support should be there (all the required jars are found).

When I use the Microsoft.NET wsdl.exe tool to create C# stubs I get the following error:

Microsoft (R) Web Services Description Language Utility
[Microsoft (R) .NET Framework, Version 1.1.4322.573]
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.

Error: Unable to import binding 'DeziroSoapBinding' from namespace 'http://localhost/api/Deziro'. - Unable to import operation 'doAttachement'. - The datatype 'DataHandler' is missing.

If you would like more help, please type "wsdl /?".

Using the wsdl tool from Apache I get a nice stub for my service:
package com.cuhka.soap.service;

public interface Deziro extends java.rmi.Remote { public javax.activation.DataHandler doAttachement() throws java.rmi.RemoteException; public com.cuhka.soap.model.SomeType doFoo(java.lang.String foo, java.lang.String bar) throws java.rmi.RemoteException; }

Note that I've mapped 'SomeData' to 'SomeType', but it works fine.

The "service" I have created looks as follows:
package net.lerutte.deziro.soap;

public class Deziro {


    public DataHandler doAttachement() {
                return null;
        }

        public SomeData doFoo(String foo,String bar) {
                return new SomeData();
        }
}

My /WEB-INF/server-config.wsdd is as follows: <?xml version="1.0" encoding="UTF-8"?> <deployment xmlns="http://xml.apache.org/axis/wsdd/"; xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"; xmlns:deziro="urn:Deziro"> <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>
