About Tapestry, is worth learning ?

Hi.
I have been reading an article at IBM dW regarding Tapestry that it needs HiveMind lightweight container in order to run.
My question is can I use Tapestry with Spring since I'm familiar with it ?
In the first place, do you encourage me to learn Tapestry ?
Is it easy to learn ? is it an important addition to my arsenal ? is it a powerfull framework ?
Thanks.

can I use Tapestry with Spring since I'm familiar with it ?

Yes, but Tapestry will still use Hivemind internally. It does not get in the way at all.

do you encourage me to learn Tapestry ?

I really like Tapestry. But this you will have to decide for yourself

Is it easy to learn ?

It can be. Tapestry 4.0 is easier than 3.x in my opinion. There is a steep learning curve initially (less steep if you are familiar with frameworks like JSF) because it's not like Struts or WebWork.

is it an important addition to my arsenal ?

To land a job? Probably not. To know something else. You bet!

is it a powerfull framework ?

TSS uses Tapestry for it's entire site and I believe NHL.com uses it for most if not all of it's site. I wouldn't say it's any more 'powerful' than any of the other frameworks. It's all just J2EE deep down. But it does allow you to get quick results, IMHO.
