[xwiki-devs] XWiki Components Vs Google - Guice

Hi Devs, I've looked into Google Guice to find out what's the buzz is all about. But as far as I can understand (with only about 30 mins scan through their user guide), XWiki Component management framework is more flexible than Guice. I'm not a Guice user but being familiar with XWiki Components, the closest thing I found on Guice was JIT bindings: http://code.google.com/p/google-guice/wiki/JustInTimeBindings. With access to ComponentManager, XWiki Component management framework provides components the ability to lookup for component implementations dynamically using a component hint, I didn't see anything similar in Guice. Am I missing something? Are these two frameworks mutually exclusive or something? Thanks. - Asiri
