Examples of java.util.jar.JarInputStream

java.util.jar.JarInputStream
The JarInputStream class is used to read the contents of a JAR file from any input stream. It extends the class java.util.zip.ZipInputStream with support for reading an optional Manifest entry. The Manifest can be used to store meta-information about the JAR file and its entries. @author David Connelly @version 1.37, 04/07/06 @see Manifest @see java.util.zip.ZipInputStream @since 1.2
