Hello! Not sure if this is what you're asking about, but I have an example
of binding an instance of a class. This instance is then injected via a
@Context annotation.
Instance binding happens here:
https://github.com/pofallon/jersey2-akka-java/blob/master/src/main/java/com/ofallonfamily/jersey2akka/ExampleApplication.java
Injected into resource here:
https://github.com/pofallon/jersey2-akka-java/blob/master/src/main/java/com/ofallonfamily/jersey2akka/ExampleService.java
HTH,
Paul
