Action.execute() and Action.getResources()
Struts Questions and Answers
(Continued from previous question...)
76. Action.execute() and Action.getResources()
In Struts 1.0, request handling logic is coded in Action.perform(); however, Action.perform() throws only IOException and SevletException. To facilitate the new declarative exception handling , the request handling method needs to throw Exception, the superclass of all the checked exceptions. Therefore, to both maintain backward compatibility and facilitate declarative exception handling, Action.perform() is now deprecated in favour of Action.execute().
You also have to be careful if you use DispatchAction in your existing applications. At the time of writing, the DispatchAction in Struts 1.1 beta has not yet been updated to use execute(). (A bug report has been filed in Struts' bug database.) Therefore, without modifying the DispatchAction class yourself, declarative exception handling will not work with DispatchAction subclasses.
In addition, Action.getResources() is now deprecated. Instead, you should call Action.getResources(HttpServletRequest) instead. This allows Struts to return to you the sub-application specific message resources. Otherwise, the message resources for the default sub-app will be used.
