java报错找不到依赖的类

Question

java命令报错，找不到依赖类。

zhang@zhang-PC:~/class$ java zhc.Entry -classpath .:dom4j.jar -verbose

Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException
        at zhc.Entry.main(Entry.java:9)
Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentException
        at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:418)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:351)
        ... 1 more

当前目录有依赖类的jar包 zhang@zhang-PC:~/class$ ls

dom4j.jar   xmler   zhc

而且jar包中有依赖类，就是报错找不到的那个
