[George Gastaldi (JIRA)]

    [ https://issues.jboss.org/browse/CDI-110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602771#comment-12602771 ] 

George Gastaldi commented on CDI-110:
-------------------------------------

It´s not possible to assign multiple ServiceHandlers to an interface, as InvocationContext.proceed() call should not be allowed

> The purpose of this feature is to allow interfaces and abstract classes to be automatically implemented by an invocation handler to which all abstract method invocations are delegated. The invocation handler would get "bound" to the type using the same strategy as is used for interceptor binding.
> Binding type:
> {code:java}
> @Target({ METHOD, TYPE })
> @Retention(RetentionPolicy.RUNTIME)
> @ServiceHandlerBindingType
> public @interface EchoService {}
> {code}
> Invocation handler:
> {code:java}
> @ServiceHandlerBindingType
> @EchoService
> public class EchoServiceHandler {
>     @AroundInvoke
>     public Object invoke(InvocationContext ctx) {
>         return ctx.getMethod().getName().toString();
>     }
> }
> {code}
> Usage:
> {code:java}
> @EchoService
> public interface HelloWorld {
>    String helloWorld();
> }
> {code}
