Directory list of JAR file within classpath

Question

The typically method to reference a file contained with a JAR file is to use ClassLoader.getResource . Is there a way to get the contents of a directory within a JAR files (similar to java.io.File.listFiles() )? Note that the JAR file is within the classpath and its filename might not be known during runtime.

Basically I have a bunch of non-.class resource files within a directory. At runtime I need to load each resource file contained within a known directory.

有一个名为java.class.path的系统属性，它解析jar的路径，然后使用JarURLConnection类来执行所需的操作。
