p> application.xml 中的< library-directory> 标签是JavaEE5功能，我不认为JBoss 4.3完全符合JavaEE5（可以做EJB3，是的，但只是部分支持）。

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).

所以你需要回到使用明确声明的JAR文件：

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

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

对于您的属性文件，您需要添加他们所在的目录作为java模块，所以例如：

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>
