Newbie problem moving to 'document' style requests. Help!

[Dave Belfer-Shevett <db...@homeport.org>]

Alas, I'm having all sorts of problems out of the starting block.  To
start, my sample application works fine.  My service is:

package com.arete.Webservices;

public class Sample {
        public String echoString(String what) {
                return what;
        }
}

I compile that and distribute it as a WAR file, the only warning I get
from JBoss (which I assume I can ignore) is:

11:51:00,269 ERROR [EngineConfigurationFactoryServlet] Unable to find
config file.  Creating new servlet engine config
file: /WEB-INF/server-config.wsdd

Anyway - I whip up a WSDL file, looking like this:

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
        <service name="Sample" provider="java:RPC">
                <parameter name="className"
value="com.arete.Webservices.Sample"/>
                <parameter name="allowedMethods" value="*"/>
        </service>
</deployment>

So far so good.  I use the Adminclient to punch that out to axis.  Works
great.  I can get the WSDL from the server
(http://localhost:8080/axis/services/Sample?wsdl) and I can invoke the
class (http://localhost:8080/axis/services/Sample?method=echoString).
My sample SOAP client connects and runs the method fine.  Code snippet
from teh SOAP client:

	String endpoint = "http://localhost:9080/axis/services/Sample";
	Service  service = new Service();
	Call     call    = (Call) service.createCall();

	System.out.println("Pinging 'Sample' webservice method
'echoResponse'...");
	call.setTargetEndpointAddress( new java.net.URL(endpoint) );
	call.setOperationName(new QName("echoString"));
	System.out.println("invoking...");
	String ret = (String) call.invoke( new Object[] { new
String("Hello!") } );
	System.out.println("Sent 'Hello!', got '" + ret + "'");


But, this is very simple encoding.  I'll need to pass more than just
primitives around, so I change my WSDL 'service' line to:

        <service name="Sample" style="document" provider="java:RPC">

Punch that back out with adminclient, and now when I try to call the
service from the above client, I get an exception:

org.xml.sax.SAXException: SimpleDeserializer encountered a child
element, which is NOT expected, in something it was trying to
deserialize.
        at
org.apache.axis.message.SOAPFaultBuilder.createFault(SOAPFaultBuilder.java:221)
        at
org.apache.axis.message.SOAPFaultBuilder.endElement(SOAPFaultBuilder.java:128)

The SOAP envelope being sent to the server looks like this (according to
tcpmon)

<?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>
         <echoString
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
            <arg0 xsi:type="soapenc:string"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">Hello!</arg0>
         </echoString>
      </soapenv:Body>
   </soapenv:Envelope>

I'm totally stumped where to start looking here - I'm new to SOAP, so
I'm sure I'm missing something very basic, but this has my project
completely dead in the water.

Help please!
