/**
* Accessing Resources from a JAR
File
You can construct a URL object by using the
reference of a resource in a JAR file.
The JAR file URL syntax is
jar:<url>!/{entry}
The following URL refers to an images/logo.bmp
JAR entry in a test.jar file on www.java2s.com
using the HTTP protocol:
jar:http://www.java2s.com/test.jar!/images/logo.bmp
The following URL refers to an images/logo.bmp
JAR entry in a test.jar file on the local file system
in the c:\jarfiles\ directory using the file protocol:
jar:file:/c:/jarfiles/test.jar!/images/logo.bmp
To read the images/logo.bmp file from a JAR file
in the classpath, you can get an input stream
object using a class object as follows:
// Assuming that the Test class is in the CLASSPATH
Class cls = Test.class;
InputStream in = cls.getResourceAsStream( "/images/logo.bmp" )
You can also get a URL object for an entry in your
JAR file, which is in your classpath as follows:
URL url = cls.getResource( "/images/logo.bmp" );
