Re: [jersey-dev] Internal request with new UriInfo

[Martynas Jusevičius <martynas@xxxxxxxxxxxxx>]

Thanks. Yes I instantiate Resource on my own.

It’s because in 2.x there does not seem to be any mechanism to lookup resource by URI? While in 1.x there was ResourceContext.matchResource():

https://github.com/eclipse-ee4j/jersey/issues/2444

The issue is now 7 years old - how come it’s not implemented in 2.x?

So I need my own UriInfo implementation? Or can I reuse one somehow?

So you instantiate the Resource class on your own? I am afraid that you
need to instantiate the correct UriInfo on your own, too.

For the sub-resource case, JAX-RS Spec. Section 3.2 says: Objects
returned by sub-resource locators (see Section 3.4.1) are expected to be
initialized by their creator.

Thanks,

Jan
