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鈥檚 RI and MyFaces.聽
Struts緙虹偣錛?/p>
ActionForms - they鈥檙e a pain
Can鈥檛 unit test - StrutsTestCase only does integration
Project has been rumored as 鈥渄ead鈥?/p>
Display Tag錛?/p>
Spring MVC緙虹偣錛?/p>
Configuration intensive - lots of XML
Requires writing lots of code in JSPs
Almost too flexible - no common parent Controller
WebWork緙虹偣錛?/p>
Small Community
Documentation is poorly organized
Tapestry緙虹偣錛?/p>
Documentation very conceptual, rather than
pragmatic
Steep learning curve - very few examples
Long release cycles - major upgrades every year
JSF緙虹偣錛?/p>
Tag soup for JSPs
Doesn't play well with REST or Security
No single source for implementation
SiteMesh錛?/p>
聽
IDE鏀寔
Struts has a lot of IDE support and even has frameworks built on top of it (i.e. Beehive鈥檚 PageFlow)
Spring has Spring IDE - only does XML validation, not a UI/web tool
WebWork has EclipseWork
Tapestry has Spindle - great for coders
JSF has many, and they're getting better and better
