使用json发生java.lang.NoClassDefFoundError: net/sf/json/JSONObject异常的解决办法 - 举头天外望,无我这般人 - 博客频道 - CSDN.NET

我已经导入了json的jar包及其需要的依赖包,过程是:右键项目选择Build path --> config build path -->add extenal jar加入以上所需要的jar。此时发现在servlet中写的关于JSONObject的代码不发生错误了,然后运行程序,在运行到json对象的代码时候发生 java.lang.NoClassDefFoundError: net/sf/json/JSONObject异常,卧槽!!我不是已经导入jar包了吗??没看到我写的代码编辑器都没报异常吗??为什么一运行就抛NoClassDefFoundError异常?

 


解决办法:打开eclipse所关联的tomcat文件夹,将所需要的jar包复制到lib文件夹里面,重启项目,问题搞定。
