Class JarURLConnection
This abstract class represents a common superclass for implementations
of jar URL's. A jar URL is a special type of URL that allows JAR
files on remote systems to be accessed. It has the form:
jar:<standard URL pointing to jar filei>!/file/within/jarfile
for example:
jar:http://www.urbanophile.com/java/foo.jar!/com/urbanophile/bar.class
That example URL points to the file /com/urbanophile/bar.class in the
remote JAR file http://www.urbanophile.com/java/foo.jar. The HTTP
protocol is used only as an example. Any supported remote protocol
can be used.
This class currently works by retrieving the entire jar file into a
local cache file, then performing standard jar operations on it.
(At least this is true for the default protocol implementation).

jarFileURLConnection
protected URLConnection jarFileURLConnection
The connection to the jar file itself. A JarURLConnection
can represent an entry in a jar file or an entire jar file. In
either case this describes just the jar file itself.
getAttributes
public Attributes getAttributes()
throws IOException Returns the Attributes for the Jar entry specified by the URL or null
if none
- The Attributes object for this connection if the URL for it points
to a JAR file entry, null otherwise
getEntryName
public String getEntryName()
Returns the "entry name" portion of the jar URL. This is the portion
after the "!/" in the jar URL that represents the pathname inside the
actual jar file.
getJarFileURL
public URL getJarFileURL()
This method returns the "real" URL where the JarFile is located.
//****Is this right?*****
getMainAttributes
public Attributes getMainAttributes()
throws IOException Returns the main Attributes for the jar file specified in the URL or
null if there are none
- The main Attributes for the JAR file for this connection
getManifest
public Manifest getManifest()
throws IOException Returns a Manifest object for this jar file, or null if there is no
manifest.
- The Manifest for this connection, or null if none
