1.考虑了两天,都没有解决的问题!!! | Copy to clipboard |
Posted by: magice Posted on: 2004-10-05 23:51 我要运行的是一个简单的邮件服务器查看程序,程序头是这么做的: import javax.mail.*; import javax.mail.internet.*; import javax.activation.*; import java.util.*; public class MailTest { …… …… 书上说要把mail.jar和activation.jar加入到classpath中, 而我的环境变量是:.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\bin; 而且我把上面两个文件放到了%JAVA_HOME%\lib中,和%JAVA_HOME%\jre\lib\ext中,编译都没有错误,但是java运行就有错误提示我: Excetipn in thread "main" java.lang.No ClassDeffoundError: javax/mail/Message 不知道怎么回事情,请大家说说看法~~~~ (mail.jar解压后有javax/mail/Message) |

Posted by: dorrenchen Posted on: 2004-10-06 12:43 you have to put the actual two jars into your classpath, like this .;%JAVA_HOME%\lib;c:/mail.jar;c:/activation.jar |
