T5 Services with diferent Implementation
I have an Interface with 2 different implementations
lets say IMyInterface MyImplementation1 Myimplementation2
until now I only needed to use one of the implementations at once, so in my
client code I just wrote @Inject private IMyInterface
and everithing was ok, now I'm on the need to use at the same time both
implementations
My first idea was to write:
binder.bind(IMyInterface.class,MyImplementation1.class).withId("Myservice1");
binder.bind(IMyInterface.class,MyImplementation2.class).withId("MyService2");
But now the question is: How I am suposed to used it from the client side( I
mean a page a component)?
@Inject MyService1?
thanks for the answer!

I haven't tested the new Tapestry-IoC AOP features yet, but I think
the answer is yes. But I don't expect it to be written by Howard.
IMHO, he must focus on Tapestry-Core and Tapestry-IoC. Someone must do
that. I even started something like that, but I headed in the wrong
direction and now I'm focusing in writing some CRUD-related open
source packages for Tapestry 5. I want to release them in the next
weeks.
I don't like the way tapestry-hibernate is implemented because, AFAIK,
it violates the three-tier architecture (separation of persistence,
business rules and user interface layers). Example: using Hibernate
sessions in page classes.

Wouldn't it be rather normal to create a tapestry-tx that provided
transaction wrappers around existing services, much the way tapestry-
spring and tapestry-hibernate do? Especially now that there's a bit
more AOP going on in T5.

1) Tapestry-IoC has a nicer way to describe services (even compared to
Spring's JavaConfig)
2) Tapestry-IoC has distributed configuration (see
http://tapestry.apache.org/tapestry5/tapestry-ioc/configuration.html),
Spring doesn't.
The only thing that prevents me from using Tapestry-IoC for
configuring all my applications' objects (services) is Spring's
transaction management.

I would use Spring to configure the type of services you are trying to
provide to your pages. I am wondering if using Tapestry services has any
advantages in this case.

Bless you man!
But wouldn't it be easy if in the docs concerning services a mock
example
will bring you through all the steps needed to do a thing that at the
end is
just merely convention??
If you naively go to look after the page
http://tapestry.apache.org/tapestry5/tapestry-annotations/
and you click to this link for enlightment, then when yo click to any of
the
two links that adress you to tapestry core and tapestry ioc, allegedly
annotations, you get a beautiful "not found".
I really apreciate your help and in general the comunity, but some rough
edges still are present in the documentation that may potentially scare
new
comers.
I apologise for the rant, but I hope you understand it is only for the
sake
of good.
So: no one can say that tapestry comunity is very responsive, but
sometimes
tapestry it's still a little bit too tricky.
Again thanks a lot.

You should be using org.apache.tapestry.annotations.Service annotation.

Almost, but now compiler doesen't know what @Service is.....
I've read the documents but they lack a sample of usage from the client side
of the service....don't know witch files I have to include (import) import
org.apache.tapestry.ioc.annotations.??
thanks a lot ....just one step and I'm done!

Thanks a lot
but now I get the following compiler error: The anotation @InjectService is
disallowed for this location.
??
BTW the location is on a regular page class:
public class TestProductDivContainer {
@Inject private Logger _logger;
@ApplicationState(create=true)
private CMSession _CMSession;
@InjectService("MyService1") private IMyInterface _CMF;
}
Before I have @Inject private IMyInterface _CMF;
