<%--方法1:  为保持代码简洁，使用sendMail()方法--%>

<% 
 try{
 email.sendMail(from,to,subject,message);
 }
 catch(beanMailer.SMTPException e){
  out.println(e.getMessage() + "<br>");
 }
%> 
<%--或方法2:  使用更复杂的脚本得到服务器的响应并捕捉错误信息。该方法比较稳妥，分细步骤执行--%>

    email.connect();

    // 2) 得到服务器响应
    try{

          out.println(email.getServerReply());
