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。


通过上面的步骤,上面的错误都全部解决了,如果你的项目还显示 有错误,就需要考虑其它原因了。
