Hi,
I'm having a problem getting a result back from a web service call. I get a
ClassCastException in the PostInvocationHandler and need some help to
resolve it.
Some background...
I have a class similar to the following:
public class Event
{
private Integer id;
private MetaData metaData;
private List<Case> linkedCases;
private List<EventLink> linkedEvents;
....
/* public getters/setters */
}
Note: MetaData is another class that resembles the following:
public class MetaData
{
private Integer gid;
private Date dateCreated;
private Date dateModified;
private Integer authorId;
private Integer modifierId;
...
/* getters/setters below */
}
Additionally, I have a SoapServlet class defined as follows:
public class SoapServlet extends XFireServlet
{
public void init() throws ServletException
{
super.init();
ObjectServiceFactory factory = new
ObjectServiceFactory(getXFire().getTransportManager(),
null);
Service service =
factory.create(EventDelegate.class,"event",null,null);
getController().getServiceRegistry().register(service);
}
}
I'm using myEclipse's web services explorer and calling the load method of
the EventDelegate. The method successfully returns an event, but I get the
stack trace below regarding the MetaData class. I see MetaData definded in
the wsdl and it appears to be correct.
Any help would be GREATLY appreciated!
