             SimpleEmail email = new SimpleEmail();
    email.setHostName("smtp.qq.com"); //Yahoo的服务器地址是：smtp.mail.yahoo.com
    email.addTo("[email protected]", "sunxiaomiao"); 
    email.setFrom("[email protected]", "木小白");
    email.setAuthentication("[email protected]", "*******");
    email.setSubject("Test message");
    email.setMsg("This is a simple test of commons-email");
    email.send(); }

Answer 1

Caused by: javax.mail.AuthenticationFailedException
QQ邮箱的smtp服务需要开启！到QQ邮箱里有个设置 开启就OK了！

Answer 2

你用的什么jar包？我有的是mail.jar
是通过Properties来设置的，感觉用的还行！

请问这个问题该如何解决呢

Answer 5

Caused by: java.lang.NoClassDefFoundError: com/sun/activation/registries/LogSupport
这个未定义

Answer 6

恩是 我看网上说的就是有冲突 但是具体是哪一个包不知道啊 网上解决的都是myeclipse的 我这找不到那个相应的啊

Answer 7

Caused by: java.lang.NoClassDefFoundError: com/sun/activation/registries/LogSupport包冲突引发程序调用错了包导致找不到LogSupport，你到referenced libraries目录中，找一下看看LogSupport这个class文件在哪个包下面然后删除相应的冲突包

Answer 8

找不到这个class文件啊 是不是和其他的jar文件有冲突啊 

Answer 9

还要重新下javaee和activation的jar文件

Answer 10

但是我用的 是eclipse啊 不是myEclipse 我再上面不是说过了吗 没有这个文件的

Answer 11

郁闷那我就不知道了。。我用myeclipse换过估计你的包版本不是新的吧。。没有那个class类
