Starting with WebWork
I started looking over Struts Shale, but something about WebWork is instead attracting my attention. I think the promise of Struts Action 2 being based on WebWork and its familiarity over the new JSF paradigm is what's making me swing that direction.
I admit that it may be more progressive to look toward JSF, but I'm just putting it off at this point. Maybe a few stumbles with WebWork will send me back to explore JSF.
Only one conclusion can be derived at this point: I'll eternally spend more time studying a framework than productively coding on an older familiar framework.
