I was implementing a custom entity provider in a Jersey REST service when I came across an error during deployment: "java.lang.IllegalStateException: Not inside a request scope." That struck me as a little odd since I was trying to inject a ContainerRequestContext into a MessageBodyWriter, which should have been within request scope. After some research and this Jersey issue I found a solution.

This is what I was trying to do in my class:
 MessageBodyWriter
@Context
ContainerRequestContext crc;


...which was throwing this exception...
 Exception
java.lang.IllegalStateException: Not inside a request scope."
weblogic.application.ModuleException: java.lang.IllegalStateException: Not inside a request scope.

The solution was to inject a ResourceContext instead and then look up the ContainerRequestContext when needed.

So my injection code became:
 MessageBodyWriter
@Context
ResourceContext resourceContext;


...and then to get the ContainerRequestContext I simply got it from the ResourceContext like so:
 MessageBodyWriter
ContainerRequestContext crc =
resourceContext.getResource(ContainerRequestContext.class);


This worked with Jersey 2.x (2.25.1 in my case).
