That's a ridiculous statement. Of course EJBs scale - that's precisely what the technology was designed for.

Should fit on a single medium box (if not a laptop) if you do it right. You have to worry about creating objects if you write your own framework (you can put beans in session or requests, and request is better mostly), and then you have 2 projects, your app and a framework, and you won't do better than the Struts team and what about framework bugs? Also, with Struts, my clients are able to write several modules(pages) per day per developers, how's that for productivity or beating the schedule? Some of the Struts sites are 50 times more concurrent users I have worked on, no problem. The slow part is DAO in J2EE (and ADO in .NET). Avoid any EJB, they do not scale. Some good choices is RowSet(I do metadata w/ reflection to auto gen SQL updates - RowSet also avoids BO/DTO/VO mapping and GC), Resin, pgSQL, Eclipse or CodeGuide IDE, Linux/KDE and J:Rockit VM or IBM VM (Sun VM and Sun Inc. have issues).

We are going to use J2EE as the ground platform. I am now considering some design choices where using Struts is one of them. However I have some questions regarding the performance of Struts.
