Apache SOAP Client for .NET Web Service

We have our application currently working with Apache SOAP client and calling "aspx page". We are migrating to have .NET Web Service (asmx page). I would like to know how we can invoke the .NET Web Service by using existing Apache SOAP 2.3 Client. We are successful if we use Apache Axis, but need to know if we can still work with old Apache SOAP client.

The beauty of WS (and one of their main points) is that the client and server are decoupled, so one can change without the other being affected. If the WS is implemented in a platform-agnostic way, you should be able to use the old client without changing anything. Have you run into any problems?

Thanks for your reply.

Well, our new web service accepts XML String as Input parameter and outputs XML String as Output parameter. I get below error when I run my client code.

Call call = new Call();

// prepare parameters
Vector params = new Vector();
params.addElement(new Parameter("XmlFileName", String.class, "<xml string>", null));

URL url = new URL("");
// Invoke the call.
Response resp = call.invoke(url, "<soapActionUri>");
System.out.println("resp : " + resp);


faultString=Server was unable to process request. ---> Value cannot be null

A simple way to invoke a service in .net is
1. Using Axis convert the wsdl to java(using wsdl2java)
2. It creates all the classes required.
3. you just have to call the method in the class

pls refer to :

Thanks for your reply. I had already mentioned in my earlier post that we were successful invoking web service through Apache Axis. We just want to know if its possible with Apache SOAP 2.3 Client.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
