常见错误
错误一：
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
解决方法：到D:\MyEclipse 6.5
\myeclipse\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806
\data\libraryset\EE_5目录下找到javaee.jar删除其中到mail文件夹。
错误二：
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/BEncoderStream
解决方法：
下载mail.jar和activation.jar文件加入到工程中。
