ZipFileSystem is a file system provider that treats the contents of a zip or
JAR file as a java.nio.file.FileSystem.
To deploy the provider you must copy zipfs.jar into your extensions
directory or else add <JDK_HOME>/demo/nio/ZipFileSystem/zipfs.jar
to your class path.
The factory methods defined by the java.nio.file.FileSystems class can be
used to create a FileSystem, eg:
// use file type detection
Map<String,?> env = Collections.emptyMap();
Path jarfile = Path.get("foo.jar");
FileSystem fs = FileSystems.newFileSystem(jarfile, env);
-or
// locate file system by URI
Map<String,?> env = Collections.emptyMap();
URI uri = URI.create("zip:///mydir/foo.jar");
FileSystem fs = FileSystems.newFileSystem(uri, env);
Once a FileSystem is created then classes in the java.nio.file package
can be used to access files in the zip/JAR file, eg:
Path mf = fs.getPath("/META-INF/MANIFEST.MF");
InputStream in = mf.newInputStream();
