If you understand that there are two (actually three) ways to make custom tags handlers, you'll understand the difference between both TagSupport and SimpleTagSupport.
1. Classical custom tags. That's the way tags were developped from the beginning. It's a bit tricky to use at first.
2. Simple custom tags. That's an easier (simple!) way to make tag handlers.
3. Tag Files. No
java handler, just a
jsp file.
You'll have to make tag handlers for your custom tags. TagSupport is used in number one, whereas SimpleTagSupport is used in number two.
