JSP vs Velocity what is better?

Question

What is better between JSP and velocity in - Performance - Ease of use - Ease of creating reusable components - Availability of open source 3rd parties - IDE support

Answer 1

Velocity or even better FreeMarker. In JSP you cannot have runtime dispatch for pojo hierarchies and everything is statically typed which is a pain. Moreover if you create many JSP2.0 custom tags (say more than 100-150) then your development-deployment cycle will slow down heavily due to inefficiencies of Jasper to resolve dependencies efficiently.

On the other hand JSP has great tool support.
