我计划从OSGi带有 Web 服务的 Android 开始，其中我将能够在 Android 浏览器上运行 Java Server Pages (jsp) 和 Java Servlet。
我的第一步是Knopflerfish在 Android 上安装。我从 knopflerfish 遵循了本教程：http ://www.knopflerfish.org/releases/5.0.0/docs/android_dalvik_tutorial.html
Knopflerfish 做得很好，我在 Android 手机的浏览器上看到了 localhost:8080。
我的第二步是安装Pax Web在也安装在 Android 上的 Knopflerfish 上。我也从这里遵循了他们的教程：http ://www.knopflerfish.org/kf_pax_web_tutorial.html
教程说：
卸载 KF HTTP 包
第一步是停止 HTTP 根包并卸载 JSDK 和 HTTP-server 包，因为 PaxWeb 将接管此功能。通常，您很可能还想卸载 HTTP-root-bundle，但在本教程中，我们将保留它的安装状态。确保在进行下一步之前刷新包。
然后：
安装 PaxWeb
第二步是从 PaxWeb 安装并启动以下包。
- pax-web-jsp-1.0.2.jar（安装）
- pax-web-jetty-bundle-1.0.2.jar（安装和启动）
- pax-web-extender-war-0.8.0.jar（安装和启动）
捆绑包Pax Web已成功安装。
问题
Pax Web无法启动捆绑包。
当我尝试启动HTTP-root-IMP它是一个 Knopflerfish 包时，它在控制台上给了我这个错误消息。

另一个是我Pax Web将从 Knopflerfish 的教程中启动捆绑包。在这里，我尝试开始pax-web-jetty-bundle-1.0.2.jar (OPS4J Pax Web - Jetty Bundle)：
[stderr] ## DEBUG: errors - FrameworkErrorEvent bundle #16
[stderr] ## DEBUG: errors - FrameworkErrorEvent throwable:

最后，当我尝试运行pax-web-extender-war-0.8.0.jar (OPS4J Pax Web - Extender - War)此错误消息时，也会出现：
[stderr] ## DEBUG: errors - FrameworkErrorEvent bundle #17
[stderr] ## DEBUG: errors - FrameworkErrorEvent throwable:

我也尝试启动pax-web-jsp-1.0.2.jar (OPS4J Pax Web - Jsp Support)显示此错误消息：

根据我从错误消息中了解到的情况，捆绑包正在寻找这些包。有什么办法可以解决这个问题，并能够使用 OSGi 框架在 Android 上成功运行 Java Web 应用程序？
