Struts: All dependencies vs Essential dependencies?

Question

I have a very minimal struts app I wrote some years ago. I want to upgrade it from 2.3 to 2.5. I'm wondering what requirements would allow the use of the essential dependencies jar. I am using only jstl tags, no struts tags. And my app is pretty simple.

Answer 1

There are an essential dependencies to download, is that what are you looking for?

All the tags are included in the struts2-core.jar, there is a plan to exclude them into plugins and have just pure core MVC engine.
