You can obtain the request by asking the ActionContext or implementing ServletResponseAware. Implementing ServletResponseAware is preferred.
The response is available on the ActionContext instance, which is made available via ThreadLocal.
|When the servlet-config Interceptor sees that an Action implements ServletResponseAware, it passes a reference to the request the Action's setServletResponse method.|
|It is more difficult to test Actions with runtime dependencies on HttpServletReponse. Only implement ServletResponseAware as a last resort. A better approach to solving a use case involving the response may be with a custom Result Type.|
