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"

| <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",

|
| @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.
