Where is this class "HttpContext" exist in glassfish jersey 2.9 . I was using jersey 1.17.1 to use HttpContext where it was exist in package com.sun.jersey.api.core.HttpContext.
But i did't find it in jersey 2.9.
Jersey 2.x had a lot of breaking changes, which partly caused by the fact that JAX-RS standard incorporated a lot of things in Jersey 1.x.
To quote https://jersey.java.net/documentation/latest/migration.html#mig-1.x
This chapter is a migration guide for people switching from Jersey 1.x. Since many of the Jersey 1.x features became part of JAX-RS 2.0 standard which caused changes in the package names, we decided it is a good time to do a more significant incompatible refactoring, which will allow us to introduce some more interesting new features in the future. As the result, there are many incompatibilities between Jersey 1.x and Jersey 2.0. This chapter summarizes how to migrate the concepts found in Jersey 1.x to Jersey/JAX-RS 2.0 concepts.
The migration chapter does not indicate what happened to HttpContext, but it no longer exists in its old form.
