我已经下载javamail的包和jaf的包
并配置了classpath如下：
C:\j2sdk1.4.2_07\lib\mail.jar;C:\j2sdk1.4.2_07\lib\activation.jar;
为何还是出错？？？

出错如下：
org.apache.jasper.JasperException: Unable to compile class for JSP

Generated servlet error:
D:\tomcat\work\Catalina\localhost\_\org\apache\jsp\javamail\sendmail_jsp.java:7: package javax.mail does not exist
import javax.mail.*;
