How does service event type work
 
|
Hi,
This is probably a basic question - but I could understand how it works. I am looking at controller.xml file in e-commerce application. Specific line is <request-map uri="emailorder"> <security https="true" direct-request="false"/> <event type="service" path="async" invoke="sendOrderConfirmation"/> ... I see that event is of type service, so the service is invoked when the uri is called. However what I dont understand is how are the contexts, both dispatch context and the values context for the service IN variables, passed in this case? Will appreciate any pointers |

look for:
http://docs.ofbiz.org/display/OFBTECH/Framework+Introduction+Videos+and+Diagrams #6 Service Definitions and Implementations then if you have a xml editor that reads the xsd files you will see choices. usually events are in like: script/org/ofbiz/example/example/ExampleServices.xml Ritz123 sent the following on 7/22/2008 3:47 PM: > Hi, > > This is probably a basic question - but I could understand how it works. > > I am looking at controller.xml file in e-commerce application.

Thanks for the reply BJ.
Not sure if I was clear in my question. I know where the service is defined, I also know how services are called etc. But what I dont understand in this case is where is how is the context passed? e.g every service call needs context to be passed so in this case, who is creating the context and where, is the question.

All of that is handled automatically by the request handler and the
service engine. The request handler will pass the request parameters to the service engine. The service engine will put those parameters in the context along with some other objects, like userLogin, locale, timeZone, etc. -Adrian Ritz123 wrote: > Thanks for the reply BJ. > > Not sure if I was clear in my question.

if you look in
applications/order/servicedef/services.xml for sendOrderConfirmation which takes you eventually to the org.ofbiz.order.order.OrderServices" public static Map sendOrderConfirmNotification(DispatchContext ctx, Map context) { in short you don't have to worry about it. it is done for you and you get it as context in the service (java) Ritz123 sent the following on 7/22/2008 4:38 PM: > Thanks for the reply BJ. > > Not sure if I was clear in my question.

Thanks Adrian for the reply.
Feel stupid now, now I recall that event handlers have the house keeping logic for the event, so for the completion of the thread the context is built in the ServiceEventHandler.java.
