• Ensure that servlet-config Interceptor is included in the Action's stack.
  • The default stack already includes servlet-config.
• Edit the Action so that it implements the ServletRequestAware interface.
  • The ServletRequestAware interface expects a setServletRequest method. You may wish to include a companion getServletRequest method.
• At runtime, call getServletRequest to obtain a reference to the request object.

  Info
  When the servlet-config Interceptor sees that an Action implements ServletRequestAware, it passes a reference to the request the Action's setServletRequest method.

  Tip

  It is more difficult to test Actions with runtime dependencies on HttpServletRequest. Only implement ServletRequestAware as a last resort. If the use case cannot be solved by one of the other servet-config interfaces (ApplicationAware, SessionAware, ParameterAware), consider whether an custom Interceptor could be used instead of Action code. (Review how servlet-config works for examples of what can be done.)
