[jboss-user] [JBossWS] - SchemaTypeCreator.introspectJavaProperties Exception w/ POJO

[aschmidt1978]

Hi,

I've created a simple POJO web service which has a method that returns a generated data type from an XML schema (using xjc). On deploying the web application that contains the service, I get the following exception:

java.lang.NullPointerException

Schema is as follows (classes generated with package com.example.message):

<?xml version="1.0" encoding="UTF-8"?>
  | <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/MessageService" xmlns:tns="http://www.example.org/MessageService" elementFormDefault="qualified">
  | 
  |     <complexType name="ComplexMessageType">
  |     	<sequence>
  |     		<element name="MessageContent" type="string"></element>
  |     		<element name="ServerTime" type="dateTime"></element>
  |     	</sequence>
  |     </complexType>
  |     
  |     <element name="ComplexMessage" type="tns:ComplexMessageType"></element>
  | </schema>

POJO Web service code is as follows:

package com.example.service;
  | 
  | import java.util.GregorianCalendar;
  | 
  | import javax.jws.*;
  | import javax.xml.datatype.*;
  | import com.example.message.*;
  | 
  | @WebService(name="Example", serviceName="ExampleService", targetNamespace="http://www.example.org/MessageService")
  | public class ExampleService implements ExampleServiceSEI {
  | 
  | 	@WebMethod(operationName="EchoMessage")
  | 	public @WebResult(name="OutMessage") String echoMessage(@WebParam(name="InMessage") String message) {
  | 		return "Hello, " + message;
  | 	}
  | 
  | 	@WebMethod(operationName="EchoComplexMessage")
  | 	public @WebResult(name="OutMessage") ComplexMessageType echoComplexMessage(@WebParam(name="InMessage") String message) {
  | 		ComplexMessageType result = new ObjectFactory().createComplexMessageType();
  | 		result.setMessageContent("Hello, " + message);
  | 		try {
  | 			result.setServerTime(DatatypeFactory.newInstance().newXMLGregorianCalendar(new GregorianCalendar()));
  | 		} catch (DatatypeConfigurationException e) {
  | 			// TODO Auto-generated catch block
  | 			e.printStackTrace();
  | 		}
  | 		return result;
  | 	}
  | 
  | }
  | 

This deployment was done on a clean install of jboss-4.0.5.GA from the jems-installer-1.2.0.GA installer package.

Is there something I've missed, or is this feature slated for the next JBossWS release? If there's something that needs to be done re: configuration or updating software, what is it?

Has anyone else experienced this problem?

Thanks in advance.
