org.xml.sax.SAXException: SimpleDeserializer encountered a child element

[Madhu]

Hi,
I'm trying to run a HelloWorld web service using Apache Axis 1.2 on WSAD 5.1.2.

I've exposed a method which takes a String argument and prints it to the console..The method does not return anything..

The following is the wsdl and wsdd..

<wsdl:types>
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://myaxis.server.com" elementFormDefault="qualified">
<element name="in0" type="xsd:string"/>
</schema>
</wsdl:types>
<wsdl:message name="sayHelloResponse">
</wsdl:message>
<wsdl:message name="sayHelloRequest">
<wsdl art name="in0" element="impl:in0"/>
</wsdl:message>
<wsdl ortType name="HelloAxisSEI">
<wsdl peration name="sayHello" parameterOrder="in0">
<wsdl:input name="sayHelloRequest" message="impl:sayHelloRequest"/>
<wsdl utput name="sayHelloResponse" message="impl:sayHelloResponse"/>
</wsdl peration>
</wsdl ortType>
<wsdl:binding name="HelloServiceSoapBinding" type="impl:HelloAxisSEI">
<wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl peration name="sayHello">
<wsdlsoap peration soapAction=""/>
<wsdl:input name="sayHelloRequest">
<wsdlsoap:body use="literal"/>
</wsdl:input>
<wsdl utput name="sayHelloResponse">
<wsdlsoap:body use="literal"/>
</wsdl utput>
</wsdl peration>
</wsdl:binding>
<wsdl:service name="HelloAxisSEIService">
<wsdl ort name="HelloService" binding="impl:HelloServiceSoapBinding">
<wsdlsoap:address location="http://localhost:9080/axis-war/services/HelloService"/>
</wsdl ort>
</wsdl:service>
</wsdl efinitions>


WSDD

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

<service name="HelloService" provider="java:RPC" style="document" use="literal">
<parameter name="wsdlServiceElement" value="HelloAxisSEIService"/>
<parameter name="wsdlServicePort" value="HelloService"/>
<parameter name="wsdlPortType" value="HelloAxisSEI"/>
<operation name="sayHello" qname="q0:sayHello"
soapAction="" xmlns:q0="http://myaxis.server.com"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<parameter qname="q0:in0" type="xsd:string"/>
</operation>
<parameter name="className" value="com.myaxis.HelloAxisImpl"/>
<parameter name="allowedMethods" value="sayHello"/>
<parameter name="wsdlTargetNamespace" value="http://myaxis.server.com"/>
</service>
</deployment>

And the JSP client code...

<%
org.apache.axis.client.Service s = new org.apache.axis.client.Service();
org.apache.axis.client.Call c = (org.apache.axis.client.Call) s.createCall();
c.setTargetEndpointAddress("http://localhost:9080/axis-war/services/HelloService");
c.setOperationName("sayHello");

try {
c.invoke(new Object[] {"Hello"});
} catch (Exception e) {
e.printStackTrace();
}
%>

The following exception is thrown if I try accessing the service..

org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.

Could anyone pls let me know the problem?
