My Experience
Struts: used since June 2001 - same time 1.0 was released. Spring MVC: used since January 2004 - before 1.0 was released. WebWork: used since July 2004. Tapestry: used since July 2004. JSF: used since July 2004 - both Sun’s RI andMyFaces.

Struts
Pros: The “Standard” - lots of Struts jobs Lots of information and examples HTML tag library is one of the best Cons: ActionForms - they’re a pain Can’t unit test - StrutsTestCase only does integration Project has been rumored as “dead”
