Should I learn JSTL?

The real beauty of JSTL is that it makes it difficult to put logic in JSPs. I prefer Velocity as a templating solution these days. It’s better for UI developers, because the template is the page. The visual is there; Java developers add the pieces that actually get the dynamic data later.
