OSGi与OSGi WAB捆绑在一起

Question

我是开发OSGi捆绑包和OSGi WAB的新手。我使用的是 Jboss AS 7.1 服务器，其中我应该同时使用 OSGi 捆绑包和 WAB。我对 WAB 的依赖很少是 OSGi 捆绑包，捆绑包和 WAB 都在我服务器的"部署"文件夹中。当我部署我的WAB时，它会在"WEB-INF/lib"中查找依赖项。如何在不将这些捆绑包添加到"WEB-INF/lib"中的情况下包含 WAB 文件外部的依赖项的捆绑包？

提前谢谢。

编辑：
我按照此链接中提供的步骤进行操作：
http://www.rpgnextgen.com/wiki/doku.php?id=vaadin_7.4_osgi_web_application
我成功地创建了一个WAB文件。我在"部署"文件夹下的服务器中将所有必要的 Vaadin 依赖项部署为 OSGi 捆绑包。当我部署我的 WAB 文件时，不包括"部署"文件夹下的 Vaadin 依赖项，但 WAB 文件正在"WEB-INF/lib"路径中查找 Vaadin 依赖项。下面是我正在使用的绒球.xml。

基本上，我要做的是创建一个WAB项目，该项目使用其他捆绑包作为依赖项，而不是在.war文件中使用"WEB-INF/lib"。
当我将 war 文件部署到服务器时，我最终得到以下异常：

Answer 1

好的，这是一个真正的旧版本的Pax-Web（当前版本是4）。
这种行为的原因是，为了给@NeilBartlett一个解释，为了能够掌握所有可能的标签库。
Pax-Web 容器遍历导入的捆绑包，并在此捆绑包中查找标记库，以使它们可供 JSP JasperCompiler 使用。
这是随着时间的推移而改进的部分之一。在Pax-Web的1.x中完成的方式有点"蛮力"，但需要容器返回有效的"捆绑"URI。与标准相比，看起来像 JBoss 容器。Felix和Equinox的工作方式不同。
