Hello,
I'm trying to set up a simple web service that returns a StockData object that has 4
properties. From my client, I can invoke the service and I can step through the method in
the debugger and see that an object is created and populated. However, when the method
returns at the client the object is null.
The endpoint in a JSR 181 EJB3:
Interface:
|
| @Remote
| public interface WeatherService {
| public StockData getStockData(String title);
| }
|
| Implementation:
|
| @WebService(name = "WeatherService", targetNamespace =
"http://org.test", serviceName = "WeatherService")
| @SOAPBinding(style = SOAPBinding.Style.RPC)
| @Stateless
| @Remote(WeatherService.class)
| @RemoteBinding(jndiBinding = "/ejb3/EJB3EndpointInterface")
| public class WeatherServiceBean implements WeatherService {
| @WebMethod
| public StockData getStockData(final String title) {
| StockData stockData = new StockData(title, 1, 234, true);
| return stockData;
| }
| }
|
|
| SOAP Request:
|
| <soapenv:Envelope
| xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
| <soapenv:Body>
| <s0:getStockData
| xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

| xmlns:s0="http://org.test">
| <String_1>SomeTitle</String_1>
| </s0:getStockData>
| </soapenv:Body>
| </soapenv:Envelope>
|
| SOAP Respose:
|
| <env:Envelope
| xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
| <env:Header />
| <env:Body>
| <ns1:getStockDataResponse xmlns:ns1="http://org.test">
| <result xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

| </ns1:getStockDataResponse>
| </env:Body>
| </env:Envelope>

name="WeatherServicePort">
| <soap:address
location="http://DFVGM71J:8080/WebServiceEJB/WeatherServiceBean"/>
| </port>
| </service>
| </definitions>
I can't work this out. If I change the return type to a String then my client gets
the value. What am I doing wrong?
Chris.
