Hi, Pradeep.
Thank you for your interest. In Tuscany SCA, we already have a few bindings
including binding.atom and binding.rss that support the RESTful style. To
model an SCA component as a web resource, it has to follow certain patterns.
At this moment, we use SPIs [1] to define the resources. And the SCA
components that are configured with binding.atom or binding.rss have to
"implement" the SPIs.
JAX-RS APIs provide a set of annotations and associated classes/interfaces
that may be used with POJOs in order to expose them as Web resources. The
specification also defines object lifecycle and scope. We can take advantage
of the JAX-RS POJOs as the implementations for RESTful services. Here are a
few thoughts I have in mind:
1) Support the JAX-RS POJOs as the SCA component implementation for RESTful
bindings such as binding.atom or binding.rest (TBD)
2) Integrate the JAX-RS engine with Tuscany's ServletHost SPIs which is an
extension point to plug in HTTP containers.
3) Integrate the data representations (media types, encoding) of JAX-RS web
resources with Tuscany's databinding framework to facilitate flexible data
formats.
4) Explore the client APIs (not defined by the JAX-RS spec) to help SCA
components to consume RESTful services.
5) Anything else that are interesting ... use your creativity here.
Thanks,
Raymond

Subject: [GSOC 2009] implementing JAX-RS support.
Hi devs,
I Pradeep Fernando is undergraduate student from computer science &
Engineering Dept, University of Moratuwa
Sri Lanka.While I was searching for appropriate project for this
summer i came across your wiki [1].
Out of these project ideas, I'm really interested in
Add an implementation type to support JAX-RS so that we can provide
RESTful services.
Currently I'm going through tuscany quickstart guide & other
documents. I went through the JAX-RS specification
(jsr-311) . It is an annotation based mechanism to enable RESTful
support.Though I understand the specification
for some extent i don't have an idea about how to implement this in
Tuscany, since i don't have a broad knowledge
in tuscany implementation. So your ideas , tips, guidelines are mostly
welcome.
I have prior experience in the web-services domain & REST.I have
contributed to apache axis2 as a developer to enhance its
REST capabilities.So Im very much familiar with java & xml. Think I'm
in a good position to take up this project. wdt?
Plz give your suggestions & ideas,
cheers,
Pradeep Fernando.
