Hi,
I would like to re-activate the already mentioned issue of lack of support of DI in sub-resources.
Usually you are going to separate JAX-RS resources and services into separate classes. In that case services are going to be injected into resource with @Inject (it works already fine in Java EE 6).
However: usually JAX-RS runtime is navigating from the main Resource to the sub-resource class via the @Path annotation.
As developer you are creating a sub-resource using an ordinary "new" and a constructor with parameters. The sub-resources instance is no more managed and injection is not available.
Proposal: we need a way to pass an instance to a JAX-RS runtime to inject dependencies.
Btw. parameterless constructors are not enough - usually you are going to pass some context from the main resource to the sub resources.
