> Align to JAX-RS deployment model.
> ----------------------------------
>
> Key: NXP-4804
> URL: https://jira.nuxeo.org/browse/NXP-4804
> Project: Nuxeo Enterprise Platform
> Issue Type: Improvement
> Affects Versions: 5.3 GA
> Reporter: Bogdan Stefanescu
> Assignee: Bogdan Stefanescu
> Priority: Major
> Fix For: 5.3.1
>
>
> Use the JAX-RS Application logic to deploy jAX-RS applications.
> This way any pure JAX-RS application can be deployed in Nuxeo.
> Also, it deprecates the resteasy adapter since using the jax-rs deployment
> model you can deploy webengine modules and JAX-RS apps on any jax-rs backend
> without the need of an adapter.
> Specific resteasy adapter feaures like guard and tx annotations on methods
> will be lost (anyway for now these features are not used by WE modules)
> Per resource tx annotation will be possible to be implemented later in a
> portable way using @TransactionAttribute on resource class.
> Also, the hot reloading mechanism will be deprecated (no more usable) since
> it requires full control over the JAX-RS engine which is not portable between
> backends. A new hot reload mechanism will be provided - with less granularity
> on the scope of the reload than the former one - so it will redeploy all
> modules (and not only the one that changed) - but more portable.
> The hot reload will be available only for jersey (at least in a first step)
> The task will be done in several steps:
> 1. cleanup/prepare existing code to the JAX-RS deployment model.
> 2. Implement JAX-RS deployment
> 3. Modify webengine-base to use the JAX-RS application deployment model.
> 3. Deprecate resteasy adapter and switch to jersey which will become the
> default backend (since it is closer to the specs than resteasy, solves some
> important bugs existing on resteasy and also provides nice features like the
> possibility to plug-in IOC engines like guice)
> 4. Update existing JAX-RS code that use the old and dirty way of declaring
> root resources or body message reader/writers (though static blocks) to
> switch to new deployment model.
> 5. As the hot reloading mechanism will be deprecated a new one will be added
> that works with jersey.
> 6. switch to jersey
> 5. Update eclipse plugins to use the new reload mechanism. (notification will
> change)
> Note that regular WebEngine modules are not affected since they are
> completely managed by webengine ...
