Hi Justyna,
Jersey 2.x does not have any API which would tell you to which resource and resource method the request will match. Neither validation is fully publicly exposed. If you want to use introspection modeler, you can use Resource builder API. Example:
Resource resource = Resource.builder(MyJaxRsResource.class).build();
and then use resource to get information about resource (IntrospectionModeller is used to construct Resource).
See
https://jersey.java.net/documentation/latest/resource-builder.html
