    • processDispatchResult

      protected void processDispatchResult(Object result, ActionContext context)
      Interprets the specified dispatch result. Subclasses should override this method to provide custom result type handling. Four handlings are automatically provided:
      1. null type means the response was handled directly, and therefore no extra processing is perform
      2. ForwardConfig type is the classical response, and will be stored in the context
      3. String type represents the name of a required forward to lookup, and will be stored in the context
      4. Void type means the method had no return signature, and select the Action.SUCCESS action forward and store in the context
      Parameters:
      result - the result value
      context - the current action context
      Throws:
      IllegalStateException - if unknown result type or the forward cannot be found
