Hi to all,
I'm trying to write a Webservice wich has to send complex object/java types over thw wire. Although I already wrote custom (de)serializer factories wich should filter the javaTypes I don’t need do serialize, I still get a SAXException.
While I’m watching at tcpmon, SOAPMonitor respectively I just see that the request was send but an error occured at the server side. De facto I always get a HTTP/1.1 500 Internal Server Error..!
Here’s the error message:
AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. faultActor: faultNode: faultDetail: {http://xml.apache.org/axis/}stackTrace: AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. faultActor: faultNode: faultDetail:

Here some code fragments from my webservice:
(1) Client Code: ****************
public class TestClient {
public static void main(String[] args) throws Exception {
Options options = new Options(args);
Person person = new Person(); ... //some getters ... Service service = new Service(); Call call = (Call)service.createCall();
QName qn = new QName("urn:StateObjectService", "Person");
call.registerTypeMapping(Class.class, qn, new ClassSerializerFactory(Class.class, qn), new ClassDeserializerFactory(Class.class, qn));
call.registerTypeMapping(Person.class, qn, new MyBeanSerializerFactory(Person.class, qn), new MyBeanDeserializerFactory(Person.class, qn));
String result;
try { call.setTargetEndpointAddress(new java.net.URL(options.getURL())); call.setOperationName(new QName("StateObjectProcessor" "processStateObject")); call.addParameter("arg1", qn, ParameterMode.IN); call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
result = (String) call.invoke(new Object[]{person}); } catch(AxisFault fault){ result = "Error: " + fault.toString(); fault.printStackTrace(); } System.out.println(result); } }
(2) Service Code: *****************
public class Service {
String response = new String();
public String processStateObject(Person person) {
try {
String response = "something: " + person.getSOMETHING(); } catch (Exception e) { e.printStackTrace(); } return response; } }
(3) Deployment descricptor (wsdd-file): ***************************************
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<typeMapping xmlns:myNS="urn:StateObjectService" qname="myNS:Person" languageSpecificType="java:test.stateobject.Person" serializer="test.stateobject.MyBeanSerializerFactory" deserializer="test.stateobject.MyBeanDeserializerFactory"/>
<service name="StateObjectProcessor" provider="java:RPC"> <requestFlow> <handler type="soapmonitor"/> </requestFlow> <responseFlow> <handler type="soapmonitor"/> </responseFlow> <parameter name="allowedMethods" value="processStateObject"/> <parameter name="className" value="test.stateobject.Service"/> <parameter name="wsdlTargetNamespace" value="urn:StateObjectService"/> <parameter name="wsdlServiceElement" value="ServiceService"/> <parameter name="className" value="test.stateobject.Service"/> <parameter name="allowedMethods" value="processStateObject"/>
<typeMapping xmlns:myNS="urn:StateObjectService" qname="myNS:Person" type="java:test.stateobject.Person" serializer="test.stateobject.ClassSerializerFactory" deserializer="test.stateobject.ClassDeserializerFactory"/> </service> </deployment>
Useful hints or advices are very appreciated. Thanks!!
Best regards Kai
