OSGi——运行工具箱的配置（org.eclipse.equinox.http org.eclipse.equinox.servlet.api）问题
前一段时间跟着老师在做有关OSGi的项目。刚从老师口中听到这个技术就两眼冒金星，感觉这就是一个高大上的技术，拿以前自己做的项目和这个一比真的是小巫见大巫。刚开始的时候信心满满，觉得一个月的时间学习加做东西足够了，可真做的时候就发现老师说的是对的，这门技术的学习曲线还是挺陡峭的。
由于刚刚找到工作，老师布置完任务后几天就去公司实习了，想着一边实习一边做OSGi，幸亏进了项目组，整个项目在我来之前已经搭建好了，逻辑也写的差不多了，我一刚刚迈出校园的大学生啥也不会，也就没让我干活（最后回学校答辩的前一天，算是在公司的第20天，这期间就让我干了一个活，修改数据库中一个表的字段名称）。所以我有充裕的时间来学习OSGi，但因为开始对自己的能力高估，并且低估了OSGi的学习难度，所以刚进公司那会问师兄公司里用啥框架，就自己学了一部分ibatis。
总体来说就是前期时间很充裕，没有好好学OSGi，后期时间紧的要命。因为当时学的时候看的是《OSGi与Equinox 创建高度模块化的Java系统》这本书。怎么说呢，这是一本好书，但是因为翻译等原因，这本书上好多概念性的东西，我都看不到脑子里去，有很多的知识都是连蒙带猜滚过的，总之我觉得入门这本书看起来挺费劲的。但因为项目中就是做书上的例子，所以只能硬着头皮看下去，这期间遇到好多问题，都是和老师还有HT一起解决的，瞬间觉得HT的学习能力超强，对整个项目把控很到位，有很多问题都是问他才解决的。
答辩的前几天我提前回到学校，和HT、SY一起再拼命做项目，写报告。为此大学最后一门课设答辩前一天我们三人通宵在教室完成。
还有好多事情就不多说了，在查找资料的期间，看到网上推荐了几本书《OSGi原理与最佳实践(完整版)》、《OSGI实战》、《OSGI-Equinox》因为一直在看《OSGi与Equinox 创建高度模块化的Java系统》，所以忽略这些书。在答辩完回公司的火车上，我觉得OSGi是一个开始，我已经喜欢上这个模块化的东西了，所以还想进一步的去了解并应用它，于是就开始看《OSGI实战》。看到前几章我就发现这真的是一本很好书，每个知识点和注意点都讲解的很清楚，以前一些模糊的地方看到这本书之后也就很清晰了。
---------------------------------------------------------------------------华丽丽的分界线-------------------------------------------------------------------------------------------------------------------------------------------
书上第六章 基于OSGI框架(Equinox)的实战 中第二节 配置工具，按着作者的讲述来进行操作时，出现了错误。首先看一下我的JDK版本
看一下我的eclipse版本号
可能和作者的有区别，所以出现了错误
有以下几个错误
1.作者说引入：org.eclipse.equinox.http org.eclipse.equinox.servlet.api,因为eclipse中没有这两个bundle，所以需要下载，但是他给的网址因为时间问题链接已经失效了，根据错误提示，我就从Google了org.eclipse.equinox.http_1.0.0.v20060601a.jar这个内容，出现了如下内容：
选择第一个搜索结果后打开的是 http://archive.eclipse.org/eclipse/equinox/drops/R-3.2-200606291905/index.php 的是这个地址
如图：
选择下载这个bundle，并放到eclipse目录下的plugins文件夹下。此时如果你在run configuration中寻找这两个bundle，也是找不到的，千万不要忘了重启eclipse。
重启之后再运行，本来以为会万事ok了，其实不然，你会发现还是不行，会看到如下错误：
那就按着报错再引入这个缺失的bundle试试吧
这次总行了吧，好事多磨，还是有错，千万不要急，考验程序猿的时候到了，认真读错误提示：
或许会找到这个提示：

如果你按着错误提示查找
org.apache.felix.service.command
把org.apache.felix.gogo.command org.qpache.felix.gogo.runtime org.apache.felix.gogo.shell这个三个bundle勾上，再运行试试吧。
这次没有错了。
什么？
你的还有错？
别急，再看看错误提示

osgi> 看到这句话
!MESSAGE Port 80 is use如图：
怎么改呢，还是在刚才的run configuration下，有个 Arguments标签栏，在VM arguments: 中加入下面这段话
-Dorg.osgi.service.http.port=8080
一般用到的是1到65535，其中0不使用
一般的应用程序使用1024到4999用来通讯
5000以后的用来用户自定义端口
遵循这个约定就可以随便取了。
运行没有错误之后，输入ss之后会发现此时正在运行的bundle：
