Summary
In this chapter, we showed you how to create
your own tag libraries. We described the steps necessary to
allow your tags to process EL-based expressions. It is
important to design your tag libraries to be compatible with
the JSTL tag libraries. That way, you won't have to design the
common formatting and iteration tags that make up the JSTL tag
library.
In the next (and final) chapter, you'll learn
how to tie everything together. We explain how to deploy Web
applications that consist of a mixture of custom tag
libraries, JSTL, and JSP code. These components can all be
combined into one common file called a Web Archive (WAR)
file.
Debugging is an important aspect of Web
development. In the next chapter, we also examine how to debug
JSTL tag libraries. We show you how to output trace
information, read error messages, and use the JDK 1.4 logging
API with Tomcat.
