《java编程艺术》上的chapter5上的例子编译不了！求助ing!!!
我把书上的代码抄上去了（是不是好傻，不要笑我！）编译的时间老是出现Message类和Session类解析不了！（cannot resolve symbol)。我知道这两个方法是mail.jar中的方法。我按照书上所介绍的方法：javac -classpath .;E:\Sun\AppServer\lib\mail.jar;E:\Sun\AppServer\lib\activation.jar EmailClient.java MessagesTableModel.java ConnectDialog.java DownloadingDialog.java MessageDialog.java
我能够在e:\Sun\AppServer\lib下找到这两个文件
请问：出现这种错误是不是没有加载mail.jar和activation.jar的原因？还是另外的缘故？应该怎么样才能编译呢？
就算是很弱智，肯请各位帮忙！！！！在线等待中！！！！！！！！！！！

还有再问你一个问题：书上说可以更新classpath环境变量设置。就是不用javac -classpath====这么长了！？？Top
