做邮件系统遇到可一点问题
在处理发送邮件的jsp文件中已经引入了
<%@   page   import= "javax.activation.* "%>
<%@   page   import= "java.util.*,javax.mail.* "%>
<%@   page   import= "javax.mail.internet.* "%>
这些是javamail和jaf的类文件包，而且已经把javamail和jaf的mail.jar和activation.jar加到了classpath里为什么编译文件时还会报错：
不认识，无法解析Session   ,MimeMessage,InternetAddress等等这些类呢????
错误提示是:
