Question

我下载了apache karaf 4.x并安装了＆＃39; war＆＃39;功能和karaf-doc包使用以下命令：

feature:install war
bundle:install -s mvn:org.apache.karaf/manual/4.0.0/war

但是karaf无法加载该网络包：

我该如何解决这个问题？

Answer 1

如果你这样做，4.0.0中的Karaf doc包实际上有一个问题：

feature:install war
bundle:install -s mvn:org.apache.karaf/manual/4.0.3/war

它立即开始工作。只需导航到

http://localhost:8181/karaf-doc/

您可以通过以下方式查看已部署的应用程序：

karaf@root()> web:list
ID | State       | Web-State   | Level | Web-ContextPath | Name
-----------------------------------------------------------------------------------------
97 | Active      | Deployed    | 80    | /karaf-doc      | Apache Karaf :: Manual (4.0.3)

我怀疑OSGi正在死亡，实际上反之亦然，但这是一种偏见基于它的Apache Karaf和ServiceMix已经准备好投入生产，不了解处女座。
