David Blevins resolved TOMEE-1040.
----------------------------------
Resolution: Fixed
> Abstract Dynamic Beans
> ----------------------
>
> Key: TOMEE-1040
> URL: https://issues.apache.org/jira/browse/TOMEE-1040
> Project: TomEE
> Issue Type: New Feature
> Reporter: David Blevins
> Fix For: 1.6.0
>
>
> If the bean class is abstract and implements
> java.lang.reflect.InvocationHandler, then the abstract methods will delegate
> to the bean's java.lang.reflect.InvocationHandler.invoke(..) method.
> This allows for sort of a hybrid approach where some methods can be abstract
> and handled in a reflection-like manner, while others can be implemented
> regularly.
> An interesting difference is the code takes extreme care to implement all the
> constructors of the parent class as well as the annotations of the parent
> class and any method annotations and method param annotations of abstract
> methods.
> This should allow the dynamically created class to replace the parent class
> in every way, including usage in annotation heavy APIs like JAX-RS, JAX-WS or
> CDI. I tested JAX-RS and it seems to work perfectly.
> For example see this RESTful service:
> {code}
> @Stateless
> @Path("/ejb")
> public abstract class RESTIsVeryCool implements InvocationHandler {
> @EJB
> private SimpleEJB simpleEJB;
> @javax.ws.rs.core.Context
> Request request;
> @Path("/normal")
> @GET
> public abstract String normal();
> @Path("/rest")
> @GET
> public abstract String rest();
> @Path("/param")
> @GET
> public String param(@QueryParam("arg") @DefaultValue("true") String p)
> {
> return p;
> }
> @Path("/field")
> @GET
> public boolean field() {
> return "GET".equals(request.getMethod());
> }
> @Override
> public Object invoke(Object proxy, Method method, Object[] args)
> throws Throwable {
> return simpleEJB.ok();
> }
> }
> {code}
