It wasn't long ago that we were having *exactly* the same conversation regarding Struts versus scriptlet-based applications. The more things change the more they stay the same :) If performance is a primary concern, then the best advice is to run your own benchmarks. When it comes to performance, it's not a good idea to trust anyone else's tests, because your mileage can, and probably will, vary. Often, we may not ever be talking about a difference that makes a difference. It's especially hard to compare performance between applications written by different people at different times, perhaps for different reasons. The Petstore debacle taught us that. If the decision between approaches is not obvious, then do the first interation of your application using both, and compare the results for yourself. If the decision is not important enough to justify doing one interation twice, then you might as well flip a coin and move on :) -Ted. PS - If you are coming from a Struts background, a very good JSF primer is "Mastering JavaServer Faces" by Dudney at all. * http://opensource.atlassian.com/confluence/oss/pages/viewpage.action?pageId=139 Commissions for books purchased through this link go directly to the ASF. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
