Something is wrong with my wsdl

[duffcase]

Hi I'm new to webservices, and have a issue I can't seem to figure out.

I've followed some tutorials, and made a helloworld example implementation which was written for jboss ws4ee, using RPC/literal.
It worked fine when I tested it, and all seemed nice..

Then I wanted to test my app on a mobile device, and that ment I had to rewrite the wsdl to document/literal.
The application deploys fine, and comes up in the list of services, however I get errors when trying to run a simple client, or run stub generation from Suns wireless toolkit.

The errors I get are as follows:

Client:

Deserializing parameter 'getHelloWorld': could not find deserializer for type {http://www.w3.org/2001/XMLSchema}reqElement

And from suns wireless toolkit:

error: modeler error: invalid entity name: "resElement" (in namespace: "http://www.w3.org/2001/XMLSchema")

I've been at this for three days now, trying to figure out whats wrong, but cant seem to find anything that works.. Any help at all would be greatly appreciated! :)

Here's my WSDL:

<definitions
 name="HelloWorld"
 targetNamespace="http://DefaultNamespace"
 xmlns="http://schemas.xmlsoap.org/wsdl/"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

 </xsd:schema>
</types>

 </output>
 </operation>
</binding>

<service name="HelloWorldService">
 <port name="HelloWorld" binding="impl:HelloWorldSoapBinding">
 <soap:address location="http://10.0.102.112:8080/ws4ee/services/HelloWorld"/>
 </port>
</service>


</definitions>

My client:

import javax.xml.namespace.QName;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class TestClient {

 /**
 * @param args
 */
 public static void main(String[] args) {
 try {
 System.out.println("Here we go...");

 String endpoint = "http://10.0.102.112:8080/testing123/blah/iruleimmensly";

 Service service = new Service();
 Call call = (Call) service.createCall();

 call.setTargetEndpointAddress(new java.net.URL(endpoint));
 call.setOperationName(new QName("http://what.com", "getHelloWorld"));

 for(int i=1; i<=10; i++) {
 String ret = (String) call.invoke(new Object[] { "TYPO! " + i } );
 System.out.println("Sent TYPO!" + i + ", got '" + ret + "'");
 }

 System.out.println("End of code...");
 }
 catch(Exception e) {
 System.err.println(e.toString());
 }
 }

}

If theres any more code I should supply, please tell me.
