The recent book from WROX - "Professional JSP, 2nd Edition" is 1194 pages
long. Obviously, I only had time to scratch the surface. The most important
part which I passed over (a topic of an excellent book: Gal Shachor, Adam
Chace, Magnus Rydlin -- JSP Tag Libraries, Manning, Greenwich, CT,
2001) are Tag Libraries. This is a true power of JSP -- you can design your
own tags which actually do somthing, like query a database, transfer files,
display shopping cart, etc. They allow for separation of roles when designing
Web pages. The artists can make sure that pages are nice. The programmers
can make sure that pages work.
