java Eclipse不会解析dom4j库

Question

我正在运行eclipseoxygen，在一个涉及Hibernate的项目中，需要dom4j库。我已经在构建路径中加载了库，但仍然收到相同的错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException
    at org.hibernate.ejb.Ejb3Configuration.<clinit>(Ejb3Configuration.java:153)
    at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:57)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:79)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:54)
    at jpa.Main.run(Main.java:38)
    at jpa.Main.main(Main.java:31)
Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentException
    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 6 more

这就是我的构建路径的样子：

请允许我施加你们集体的耐心，并在这件事上请求一些帮助，好吗？我已经没有办法在这里做什么了。
非常感谢
