Question

我写了一个JAVA发送邮件的例子，但是怎么样都运行不了

已经把activation.jar,mail.jar加入到该工程lib文件夹下面,jdk的lib下面也加了，然后这是classpath的配置
C:\Program Files\Java\jdk1.5.0\lib\servlet-api.jar;C:\Program Files\Java\jdk1.5.0\lib\tools.jar;C:\Program Files\Java\jdk1.5.0\lib\dt.jar;C:\Program Files\Java\jdk1.5.0\lib\activation.jar;C:\Program Files\Java\jdk1.5.0\lib\mail.jar;
然后依旧是报出
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
at javax.mail.Session.loadProvidersFromStream(Session.java:928)
at javax.mail.Session.access$000(Session.java:174)
at javax.mail.Session$1.load(Session.java:870)

at com.Yz.emailMaker.EmailSender.main(EmailSender.java:77)
是不是还和tomcat的设置有关系？
