I'm not trying to tip the discussion in any direction here, but I thought I would point out that JSF is "supposed" to be view agnostic. Render kits are being built for WML, Swing, etc. I think that it is safe to assume that JSF would move Struts AWAY from its jsp orientation. > and I'm wondering what proportion of the > exisiting Struts user base were going to loose/screw going that route? > > I guess in order to agree/disagree with this stratgey I need to go and > actullay try JSF out. > > Niall > > > > ----- Original Message ----- > From: "Sean Schofield" <[EMAIL PROTECTED]> > To: "Struts Developers List" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> > Sent: Tuesday, October 26, 2004 6:35 PM > Subject: Re: Struts Shale > > > I'm +1 on JDK 1.4 (+0 on JDK 1.5). > > > > I also agree with Craig's sentiments on keeping things as simple as > > possible and not reinventing what JSF (and other frameworks) can do > > for you. > > > > The more I look at JSF, the more impressed I am with it.
