osgi - osgi (bndtools) 中的 ReSTLet bundle 无法启动。激活器错误 com/sun/net/httpserver/HttpHandler

Question

我正在迁移到 bndtools 我创建并在标准 Eclipse 环境中工作的一些 osgi 插件。我添加了 Felix Web 控制台和Jetty HTTP 服务，并用 Felix 替换了一些 Equinox 包等价物。

当我运行一个需要 org.reSTLet.jar 的特定包时，该包会解析但不会激活。控制台输出是:

____________________________ Welcome to Apache Felix Gogo

g! 2015-05-25 00:06:33.471:INFO:oejs.Server:jetty-7.x.y-SNAPSHOT 2015-05-25 00:06:33.545:INFO:oejsh.ContextHandler:started o.e.j.s.ServletContextHandler{/,null} 2015-05-25 00:06:33.620:INFO:oejs.AbstractConnector:Started SelectChannelConnector@0.0.0.0:8080 ! Failed to start bundle org.restlet-2.3.2.v20150501-1520, exception activator error com/sun/net/httpserver/HttpHandler from: org.restlet.engine.Engine:registerDefaultConnectors#839

我尝试了基于其他问题的解决方案，即 this one建议设置运行属性 org.osgi.framework.system.packages.extra = com.sun.net.httpserver (大概在我的 bndtools .bnd 文件中)，另一个建议激活 < em>ReSTLet 应用程序使用框架监听器 -- 但这些对我不起作用，控制台输出是相同的。

我仍在学习，如果能提供解决方案的任何帮助，或者有关 bndtools 或 Eclipse 可能提供的帮助我的任何方法或功能的提示，我将不胜感激追本溯源。

顺便说一句，Felix Web Console 正在运行，作为同一插件的必需包。

这是我的 bndtools 配置:

## Uncomment if you need to change the HTTP port
-runproperties: org.osgi.framework.system.packages.extra = com.sun.net.httpserver

事实证明，在 stackoverflow.com 上针对此问题给出了其他答案，例如 this one是正确的，除了设置-runproperties: org.osgi.framework.system.packages.extra = com.sun.net.httpserver 在 bndtools 启动配置中未达到预期结果。 bndtools FAQ建议如下，这解决了我的问题:

Note that using the -runsystempackages instruction is equivalent to setting the OSGi property org.osgi.framework.system.packages.extra; however it is better to use -runsystempackages because then the Run Requirements resolver inside Bndtools will take account of the availability of those packages during resolution.
