Have you looked at the Aegis Inheritance section in the User Guide? http://xfire.codehaus.org/Aegis+Inheritance
-Øyvind -----Opprinnelig melding----- Fra: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sendt: fr 27.04.2007 01:20 Til: [email protected] Emne: [xfire-user] service method with abstract class parameter? - Couldn't instantiate class. null Our current issues revolves around calling a service method that takes in an abstract class as a parameter. e.g. public void loadGelcoCCAddendum(GelcoCCAddendum gelcoCCAddendum) throws GeneralWebServiceException; Class Hierachy: GelcoCCAddendum - Abstract Class GelcoLodgingCCAddendum - concrete subclass GelcoRentalCCAddendum - concrete subclass GelcoTravelCCAddendum - concrete subclass I would like for this loadGelcoCCAddendum() method to have the ability to handle any of the GelcoCCAddendum subclasses. The issue we are seeing is that XFire is giving us an error. I believe it is trying to instantiate the abstract class(GelcoCCAddendum) rather than the concrete class that is passed in. I would really rather not have a seperate service method for each subclass of GelcoCCAddendum. org.codehaus.xfire.fault.XFireFault: Couldn't instantiate class. null at org.codehaus.xfire.fault.Soap11FaultSerializer.readMessage(Soap11FaultSerializer.java:31) at org.codehaus.xfire.fault.SoapFaultSerializer.readMessage(SoapFaultSerializer.java:28) at org.codehaus.xfire.soap.handler.ReadHeadersHandler.checkForFault(ReadHeadersHandler.java:111) at org.codehaus.xfire.soap.handler.ReadHeadersHandler.invoke(ReadHeadersHandler.java:67) at org.codehaus.xfire.handler.HandlerPipeline.invoke(HandlerPipeline.java:131) at org.codehaus.xfire.client.Client.onReceive(Client.java:382) Any thoughts on how XFire/Aegis need to be configure to support this functionality? This seems to be a pretty basic approach but have not had any luck getting this to work! Would changing the parameter from an Abstract class to an Interface help us out at all? Thanks in advance! Bob
