Hi Andre,
sorry for top posting but I am responding from my mobile device.
Regarding 1) the org.apache.cocoon.serialization.TextSerializer migration into
c3 is ASAIK not yet done. However that should be pretty straight forward to
implement.
Yes, I was already thinking that I could do this.
Contributions are always welcome. ;)
If you or somebody else will do the migration please open an issue in
https://issues.apache.org/jira/browse/COCOON3 and attach the diff. We
will apply it ASAP.
OK, I do my best to get it done.
Actually I did lately work with the RESTController of c3 since the JAX-RS
integration was not needed for my use cases. If you choose the c3 REST way you
can use the TextResponse [1] to return your json objects to the client. In the
same package you will as well find a BinaryResponse [2] which you can use to
return binary data like images from your rest services.
The TextResponse is a good alternative, and I will certainly look into
it. It is apparently not yet part of the current alpha Cocoon
3.0.0-alpha-3 that I downloaded from the cocoon website.
No you would need the HEAD or the latest beta snapshot.
I just commited an example [3] of an asyncron processing with REST you may want to look
into. It is based on jquery on the client side but you will get the idea. If you look at
[4] you will see the basic background. The block provides a workig example when starting
with "mvn install jetty:run" and browse to localhost:8888/,
Great!
Actually I am still thinking on implementing comet
http://en.wikipedia.org/wiki/Comet_(programming) Actually long polling
should not to be too complicate to be implemented with our REST
framework (hopefully I will find some play time for implementing
that). ;)
However html5 will open some new approaches to the comet technique where
Server-sent events and websockets come into play, but I think there we
need to make some changes to our controller.
Somebody had worked with streaming message in cocoon yet?
Regarding the bean lookup, why not using autowiring in your components (more
when you use the REST part)? See [5].
Yes, that would do it.
Thanks for your valuable response.
you are welcome. I am glad if it helps you.

Hi All,
I have two questions:
(1)
I want to be to be able to return JSON to the client, typically a
browser. The client is responsible to properly present the response to
the user, typically with the Dojotoolkit. As I would like to move to
cocoon3, I was looking for a JsonSerializer or a simple TextSerializer.
With cocoon 2.2, one can simply use the TextSerializer to return JSON,
by defining
<map:serializer name="json" mime-type="application/json; charset=UTF-8"
src="org.apache.cocoon.serialization.TextSerializer">
<encoding>UTF-8</encoding>
</map:serializer>
Cocoon 3 apparently is restricted to only return XML/HTML [1], as far as
I can see. I did not find in the API any mentioning of other types of
serializers, besides XMLSerializer and FopSerializer.
If so, this would be a limitation. Especially for designing RIAs [2]
(like Twitter), it would be very useful to be able to return JSON.
So, is there a particular way to return JSON or Text.
(2)
With flowscript in cocoon 2.2, it was very easy to instantiate a Java
bean defined in some appropriate Spring bean configuration file, like
var someFacade = cocoon.getComponent("someFacade");
someFacade.doSomething(...);
Is there a recommended way in Cocoon 3 to instantiate beans. One could do
ApplicationContext context =
new ClassPathXmlApplicationContext( new String[]
{"beans-spring.cfg.xml");
SomeFacade facade = (SomeFacade)context.getBean("someFacade");
facade.doSomething(...);
within a JAX-RS resource [3].
So, is this way to do instantiate beans?
Thanks,
Andre
