Spring mvc is a framework that has been long time out there, it is well documented and proven technology. A lot of web sites are using spring.
Seam is a framework based on jsf - rich faces implementation. It has a lot of ajax based components. It uses some heavy stuff like EJB, JPA. All of this is prone to errors and this framework is so slow (at my computer it is almost impossible do develop something because it is really slow, especially redeploying on jboss) But is is very good for back office applications.
Does someone have a professional experience with this two frameworks? Can you recommend the better one ? Why?

I use both: Spring-MVC (2.5) and Seam
Because Seam uses Java Server Faces Technology (A server-side based Technology), behind the scenes, It is better designed for small and medium applications. (Each JSF view Tree is stored on Session - You can store on client side, but be aware bandwidth issues). But it has some advantages:
Typically web application uses the following path
view >> controller >> service >> domain
With Seam, you can get
view >> service >> domain
Or even (by using mediator pattern provided by Seam Framework)
No controller, No service
view >> domain
Besides that,
Spring-MVC
It has a powerful web-Tier infrastructure
But i still not use Spring 3.0 because
...
About The learning path, i think both are similar.
