Configuring applications using properties files
Now that we have learned about wsadmin and Jython scripting we can discuss how to configure applications using properties files. WAS 7 introduced to administrators the ability to use application properties files to install enterprise application files on a server or cluster, update deployed applications or modules, or uninstall deployed applications or modules. WAS 8 has extended the feature set to give administrators more functionality and control. There is a caveat, however; an enterprise application file must conform to Java, Enterprise Edition (Java EE) specifications to be able to configured using properties files.
Note
There are recommended Java blueprints on how to design applications correctly, as specified by the JEE specifications.
We will use the HR Lister application presented in Chapter 3, Deploying your Applications, to demonstrate the steps involved in installing, updating, and deleting an application, using properties files.
