在文章 Java中REST API使用示例――基于云平台+云服务打造自己的在线翻译工具 中从IBM Bluemix上下载的Java示例代码，导入到Eclipse之后，出现以上错误信息！
错误原因：
Eclipse是刚刚安装的，还没有配置服务器运行环境！
解决办法：
1、首先要安装一下Tomcat；
通常是下载一个zip压缩包，解压一下就可以了；
2、Eclipse中点击Window菜单，选择Preferences
3、在左侧展开Server，选择Runtime Environment，右侧点击Add按钮
4、在弹出的窗口中选择你的Tomcat版本
5、点击“browse”按钮选择Tomcat的安装位置，选择合适的JRE版本，点击Finish按钮完成。
