Chapter 11 supplies an example of the way a custom installer class installs an optional package
in the standard
lib/ext/
JRE directory. There, you will find information on how to write
installer code using the JNLP client API.

Summary
In this chapter we introduced JNLP from a more theoretical viewpoint than Chapter 8. In par-
ticular, we discussed some considerations regarding the adoption of such a deployment tech-
nology. Then we explored the protocol main stages and the basic JNLP file structure, covering
the two main types of descriptors, for extensions and applications. After having completed a
first, overall picture of the JNLP protocol, we are now ready to examine its details. The next
chapter will describe how the Client Environment (we introduced such a concept in Chapter 2)
can be described using the JNLP protocol.
