Java 战争中爆炸的罐子

我们可以把分解的jar文件放在war web inf库中吗？在JBoss4.2中它对我不起作用。我出现以下错误，无法部署应用程序：

如果解压jar文件，则生成的文件需要进入

WEB-INF/classes

而不是

WEB-INF/lib

中

---

尝试

WEB-INF/classes

即使我在WEB-INF/classes文件夹中复制jar文件，它也不起作用..它会给class not found EXCEPTION..让class files direclty随时都能起作用..确保保留目录结构。例如，对于class

com.foo.bar.MyClass

它需要在以下目录下找到：

WEB-INF/classes/com/foo/bar/MyClass.class

我保持了相同的目录结构..但是它在一个目录中，带有.jar扩展名..这不起作用。它需要与我的示例完全相同，即

com.foo.bar.MyClass

中的

com

必须位于

WEB-INF/classes

下。
