Re: Initialization stuff
Martin, I would not override the ActionServlet -- the plug-in approach is much better and not hard at all. Here is a simple plug in and the Martin I. Levi wrote: Is this a better solution than mine?

RE: Initialization stuff
Yeah, but I just need to do initialization when the application starts, the validator and tiles are working all the time when requests come and go. Perhaps is a good solution also, but is mine wrong or discouraged? Thats what i really would like to know.

Although I often use servlets for initialization, Paul's suggestion is better because ServletContextListener was designed exactly for initialization/finalization purposes. Using the right tool for the job is a good practice even if you gain nothing more in functionality; it makes your application components/logic easier to identify later. So i guess I should refactor too ;-) Manos - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Initialization stuff
You can do this by creating a class which implements javax.servlet.ServletContextListener. This requires a container supporting Servlet 2.3. Paul > -Original Message- > From: Martin I.
