FYI
I've started migrating sandbox code to use the new recursive SCA API.
This API has been accepted with a bunch of changes including
Jeremy's constructor injection proposal. The intent is the Tuscany
SCA API jar will be donated to/used by the spec group. A quick
overview of what has changed includes:
- Substitution of "Composite" for "Module"
- Use of generics in locateService() with the following semantics:
package org.osoa.sca;
public interface CompositeContext {
…
T locateService(Class<T> serviceType, String serviceName);
}
The locateService() method takes as its input argument the name of
the service and returns an object providing access to the service.
The returned object implements the Java interface the service is
typed with.
- serviceType is the Java type used to represent the target
service on the client name can take on one of the following forms:
- <component-name>/<service-name>
If the service-name is not provided, the name of the
serviceType sans package name will be used as the service-name
- <reference-name>
I've updated Rick's "eagerinit" sample to compile against the new APIs.
We have a few changes that will be proposed this week as well:
- Change "session" scope to conversational
- Move eager init from the scope to a class level annotation. This
will allow us to instantiate a component instance eagerly without
having to have an initializer method, which will come in handy with
constructor based injection.
Of course, if anyone has additional ideas, please propose them on the
list and we can send them off to the spec group for discussion.
