/**
|
||||
* 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:
|
||||
* <p>
|
||||
* jar:<standard URL pointing to jar file>!/file/within/jarfile
|
||||
* <p> for example:
|
||||
* <p>
|
||||
* jar:http://www.urbanophile.com/java/foo.jar!/com/urbanophile/bar.class
|
||||
* <p>
|
||||
* 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.
|
||||
* <p>
|
||||
* 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).
