InputStreamin=JProperties.class.getResourceAsStream（name）;
5。
使用class.getClassLoader（）所得到的java.lang.ClassLoader的getResourceAsStream（）方法
InputStreamin=JProperties.class.getClassLoader（）.getResourceAsStream（name）;
6。
使用java.lang.ClassLoader类的getSystemResourceAsStream（）静态方法
InputStreamin=ClassLoader.getSystemResourceAsStream（name）;
补充
Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream（）方法
InputStreamin=context.getResourceAsStream（path）;
完整的示例，可以参考附件文件
