标签在 application.xml 是一个 JavaEE5 特性，我不要认为 JBoss 4.3 完全符合 JavaEE5(它可以做 EJB3，是的，但它只是部分支持).

The <library-directory> tag in application.xml is a JavaEE5 feature, and I don't think that JBoss 4.3 is fully JavaEE5-compliant (it can do EJB3, yes, but it's only partial support).

因此您需要返回使用显式声明的 JAR 文件:

So you need to go back to using explicitly declared JAR files:

<module>
    <java>lib/core.jar</java>
</module>

至于您的属性文件，您需要将它们所在的目录添加为 Java 模块，例如:

As for your properties files, you need to add the directory that they're in as a java module, so for your example:

<module>
    <java>lib/classes</java>
</module>
