Map parameters = ActionContext.getContext().getParameters();

Implement ParameterAware

Preferred

• 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 ParameterAware interface.
  • The ParameterAware interface expects a setParameters method. You may wish to include a companion getParameters method.
• At runtime, call getParameters to obtain a Map representing the request parameters.
