Head First Servlets and JSP, 2nd Edition

When a JSP uses more than one tag library

If you want to use more than one tag library in a JSP, do a separate taglib directive for each TLD. There a few issues to keep in mind...

• Make sure the taglib uri names are unique. In other words, don’t put in more than one directive with the same uri value.

• Do NOT use a prefix that’s on the reserved list. The reserved prefixes are:

  jsp:

  jspx:

  java:

  javax:

  servlet:

  sun:

  sunw:

Fill in the spaces based on the information that you can see in the TLD. Draw arrows to indicate where the different pieces of information are tied together. In other words, for each blank, show exactly where you found the information needed to fill in the blank.
