In Listing 13.1, we can see the resources defined for the application: the core module (part
“
core
”at lines 23-25) that is composed of two JAR files, and the “draw” part that can be
downloaded when needed. Note also the optional
package
element at line 26, which suggests
where to find the given classes to the JNLP file. The extension installer defined at lines 18-21
of Listing 13.1 is invoked for installing (and uninstalling) the application. The corresponding
JNLP file is reported in Listing 13.2.
