Examples of JarURLConnection

• java.net.JarURLConnection
  oo.com/bar/baz.jar!/COM/foo/Quux.class
  

  Jar URLs should be used to refer to a JAR file or entries in a JAR file. The example above is a JAR URL which refers to a JAR entry. If the entry name is omitted, the URL refers to the whole JAR file: jar:http://www.foo.com/bar/baz.jar!/

  Users should cast the generic URLConnection to a JarURLConnection when they know that the URL they created is a JAR URL, and they need JAR-specific functionality. For example:

   URL url = new URL("jar:file:/home/duke/duke.jar!/"); JarURLConnection jarConnection = (JarURLConnection)url.openConnection(); Manifest manifest = jarConnection.getManifest(); 

  JarURLConnection instances can only be used to read from JAR files. It is not possible to get a {@link java.io.OutputStream} to modify or write to the underlying JAR file using this class.

  Examples:

  A Jar entry

  jar:http://www.foo.com/bar/baz.jar!/COM/foo/Quux.class

  A Jar file

  jar:http://www.foo.com/bar/baz.jar!/

  A Jar directory

  jar:http://www.foo.com/bar/baz.jar!/COM/foo/

  !/ is refered to as the separator.

  When constructing a JAR url via new URL(context, spec), the following rules apply:

  • if there is no context URL and the specification passed to the URL constructor doesn't contain a separator, the URL is considered to refer to a JarFile.
  • if there is a context URL, the context URL is assumed to refer to a JAR file or a Jar directory.
  • if the specification begins with a '/', the Jar directory is ignored, and the spec is considered to be at the root of the Jar file.

    Examples:

    context: jar:http://www.foo.com/bar/jar.jar!/, spec:baz/entry.txt

    url:jar:http://www.foo.com/bar/jar.jar!/baz/entry.txt

    context: jar:http://www.foo.com/bar/jar.jar!/baz, spec:entry.txt

    url:jar:http://www.foo.com/bar/jar.jar!/baz/entry.txt

    context: jar:http://www.foo.com/bar/jar.jar!/baz, spec:/entry.txt

    url:jar:http://www.foo.com/bar/jar.jar!/entry.txt
