SOAP 3 Callback Documentation

The following callback interface is designed using VS2008 and ASMX.

An implementation of a callback service is also uploaded on our project page on Sourceforge. This implemenation contains a callback service written in ASMX and in WCF.

Need to implement three core methods (getVersion, heartBeat and eventSeq):

namespace soap2.nads.econz.co.nz
{
        [WebService(Namespace = "http://soap2.nads.econz.co.nz")]
        [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
        public class NADSCallbackService : System.Web.Services.WebService
        {
                [WebMethod]
                public CallbackVersion getVersion()
                {
                        return CallbackVersion.VERSION_2; // should match the version of the callback interface
                }
 
                [WebMethod]
                public void heartBeat(int errorsSinceLastSuccess)
                {
                        // TODO: Implementation
                        // The heartbeat method is called every minute by the EService callback manager.
 
                }
 
                [WebMethod]
                public void eventSeq(UserIDBean externalServiceID, EventBean[] eventBeans)
                {
                        // TODO: Implementation
                        // This will get fired on every user interaction which changes the state of a job, i.e. create job, dispatch, etc.
                }
        }
}

• CallbackVersion enumerand definition
• UserIDBean object definition
• EventBean object definition
