关于RCP+OSGI的部署

一直有个想法做个Tomcat应用服务器监控程序的，包括数据库的参数设置，备份。日志的管理，备份，应用进程的获取，CPU占用，内存占用。

通过在Google和百度的查找最初确定为采用sigar+armchats通过web浏览器中查看。但是想来想去还是做成桌面应用程序。从而确定采用RCP+OSGI来实现

今天主要是下载了一个采用RCP+OSGI的简单JAVA应用来熟悉RCP+OSGI如何使用，在项目部署的过程中遇到了许多的问题现在将问题及解决措施都记录于下

主要提示没有找到这个类org/apache/commons/logging/LogFactory 但是我看看我自己的JAR包，没有少东西啊。

擦，明明有LogFactory.class这个类啊，myeclipse眼瞎啊。经过上stackflow google baidu，每一个方法都试了但还是没用，然后自己在runtime 中的classpath中发现commons.logging包并没有在path中，于是手动添加，解决问题了不在报上述问题了，转而报另外一种问题了我给大家瞅瞅
