想用JavaMail应经加上jar包 但是总是说找不到com/sun/mail/util/
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
但是在WEB-INF下的lib中已经有mail.jar 我还加上了activation.jar
在referenced libraries 中也有mail.jar activation.jar 但还是报错。
点开referenced libraries 下的mail.jar 明明有 LineInputStream.class
MyEclipse 还重新装过， 工作空间也换过。mail.jar 还下载了新的版本
但是错误依旧
难道是代码的问题？
我记得这一段从网上copy的代码 还用过一次
