The formalism used here is only demonstrative; every deployment solution has its own nota-
tion for managing resources.
Common Case
Usually a client configuration for a Java application is an instance of the following parameters:
• The JRE that executes the application
• Needed optional packages (if running on a J2SE environment)
• Third-party Java libraries
• Native libraries
• Native resources (platform-dependent executables, and so on)
• Underlying OS, eventually specifying its hardware architecture (for example, Solaris on
x86)
•User identity, meaningful for the deployment process
•All application resource files: JAR, ZIP, or any other file that composes the application

Many other parameters could be used when needed, such as initial heap size, locale, and so on
when meaningful for the deployment process. In Part III, we will discuss in detail how client
configurations are described under the JNLP technology. A very simple example of a deploy-
ment server that records all of its client's configurations is given in Chapter 6.
