Which web framework to use with portlets?

Spring
A lot to love here, a learning curve worth climbing, and what's not there you can expect to continue to improve. A framework and a project with a future. And on the learning curve worth climbing point: I think this is an important point, that investing time and energy in learning this framework gains a valuable skill that is applicable to portlet development, to other web application development, to deploying and configuring existing applications. A learning curve worth climbing.
JSF:

We've developed so far 15 of 40 portlet applications using Spring, JSF, and Hibernate. It is working quite well. I've made a sample portlet illustrating how these fit together and documentation explaining how it works and the difficulties I experienced. You can download it from the clearinghouse or directly.
I haven't encountered any of the issues from ericburke.com, although JSF still is relatively young (as are portlets) and there aren't enough JSF components out there yet (so write some!) and some of them don't work too well with portlets yet because they try to put CSS & JS references in <head> or they expect only HttpServletRequest.
The only architectural issues with JSF that I know of are discussed at Improving JSF by Dumping JSF and solved by facelets.
