The interpreter looks for the Main-Class value in (Crystaltech web hosting)
The interpreter looks for the Main-Class value in the manifest. Then it loads the named class as the application’s initial class. What can we do with the revision and temperament information we’ve so cleverly included in the JAR file? Unfortunately, nothing, except for unpacking the archive and reading the manifest. However, if you were writing your own JAR utility or some kind of resource loader, you could include code to look at the manifest, check for your private keywords, and act accordingly perhaps darkening the display if the artist’s temperament is moody. Another important keyword is Java-Bean. The value of this keyword should be true if the item is a Java Bean; this information is used by the BeanBox and other utilities that work with Beans (see Chapter 19).
