Having a simple taglib-based approach to do some of the more common
AJAX-y things, maybe some widgets here and there too, means that Java
developers can leverage their existing skills without having to take the
plunge into heavy client-side development, which I can say from the
experience of mentoring some junior-level teams can be a very difficult
hill to climb, regardless of what whiz-bang library you choose to use to
try and make it easier. The very nature of Javascript, for many Java
developers, is a difficult leap to make.
Today's whiz-bang libraries make things dead simple to perform ajax
requests. For instance, with jQuery to get the contents of a url and place
it in a div element #content:
$("#content).load(url);
I guess I fail to see how even junior-level team members would have a
difficult learning curve with this. Learning jQuery quickly is easy to do
and is much of the appeal.
And as others have mentioned, the libraries such as jQuery have a great user
base, with much to offer in terms of support. Just checkout the #jquery
freenode irc channel, for instance.
Part of being a developer is learning new technologies, and if those
technologies are easy to use and powerful, then that's where the ROI really
pays off. We should be nudging people in these directions with better
documentation on how to best integrate with existing libraries. This would
be a far better place to focus energy, imo.
