有劳高手帮我看看我的这个发送邮件程序？？？希望高手抽点时间给看看！！！

帮你调试了一下，发现很多错误，很多是基本的东西
1.请注意全局变量的申明，你有很多变量在一个<%%>中申明了，但别的地方还要用，请把它申明为全局的。
2.if语句的条件，在复杂的情况下请用（）；
3.请将你的此类长句byte[]  subjectTemp=request.getParameter("subject").getBytes("ISO8859_1");之类的长语句分开。
4.还有很多别的错误，正在调试.

解决方案 »

  1.   

    我用的是tomcat服务器，邮件发送程序和上面的程序差不多，出错信息是
    找不到javax.mail.*，你们是如何配置的。
    另外，我的javamail包在jdk1.3下，classpath已添加mail.jar和activation.jar。
