I know ATG, I worked with the product for a couple of years, I didn't know oracle purchased ATG.
You can not compare ATG with any other fw described by Matt Raidle, neither Tapestry at all. ATG is a full stack e-commerce solution, portal, publishing. And not opensource at all, but J2EE standard. There is no point comparing with Spring fw either. ATG is not a webframework, it is built in in his own webframework, own IoC, own ORM etc ... They even had their own application server, but they moved to weblogic. All that in order to provide the real functionality you pay for : the way to develop really big e-commerce sites. well, this is another discussion, it does not really belong to this thread.
