Class JarRevision

class JarRevision
extends BundleArchiveRevision

This class implements a bundle archive revision for a standard bundle JAR file. The specified location is the URL of the JAR file. By default, the associated JAR file is copied into the revision's directory on the file system, but it is possible to mark the JAR as 'by reference', which will result in the bundle JAR be used 'in place' and not being copied. In either case, some of the contents may be extracted into the revision directory, such as embedded JAR files and native libraries.
