Dates in Web Services

[wconroy]

I am having trouble using dates in web services. I have the following

@WebService(name = "EndpointInterface",
 targetNamespace = "http://test.com/test",
 serviceName = "TestWebservice")
@SOAPBinding(style = SOAPBinding.Style.RPC)
@Stateless
public class TestWebservice implements TestWebserviceRemote {

 @WebMethod
 public void getData(Date theDate) {
 Logger.getLogger(TestWebservice.class).info("Got Date: " + theDate);
 }
}

It produces this as the wsdl when I deploy it on 4.0.4.GA with JbossWS 1.0.1

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="TestWebservice" targetNamespace="http://skyroad.com/securitiesservice" xmlns:tns="http://skyroad.com/securitiesservice" xmlns:xsd="http:/
/www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns="http://schemas.xmlsoap.org/wsdl/">

 </types>
 <message name="EndpointInterface_getDataResponse">

 <message name="EndpointInterface_getData">

 </message>

 </operation>

 </input>
 <output>
 <soap:body use="literal" namespace="http://skyroad.com/securitiesservice"/>
 </output>
 </operation>
 </binding>
 <service name="TestWebservice">
 <port name="EndpointInterfacePort" binding="tns:EndpointInterfaceBinding">
 <soap:address location="http://dlnx07.skyroadtech.com:8080/securitiesServiceWS/TestWebservice"/>
 </port>
 </service>
</definitions>

When I try to consume the service, the server throws the following exception

Is there something that I need to do in order for the dates in my request to get parsed correctly? I have looked through the samples, but they are very trivial and dont seem to have dates.

Hi,
I solved the same problem using Calendar instead of Date for each parameters in SEI's methods; Calendar and Date are both mapped to xsd:dateTime.

I was thinking about doing that, but I have the issue that I have some complex objects that I want to be part of my request that have dates in them. I have existing non- web service apis that take dates and I dont want to have to do the calendar/date translation myself. Is there no way to specify that I want to use a date instead of calendar?
