javamail 发送邮件出错 急急！！！

Question

发送邮件的servlet; 这个是简单的文本发送但是就是有错 发送不成功 请大家看看 说是Transport.send(msg); 
这条语句出错 public class Send extends HttpServlet { public Send() { 
super(); 
} public void doPost(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException { response.setContentType("text/html"); 
PrintWriter out = response.getWriter(); 
request.setCharacterEncoding("gb2312"); 
String from = request.getParameter("from"); 
String to = request.getParameter("to"); 
String subject = request.getParameter("subject"); 
String context = request.getParameter("context"); 
System.out.println(from); 
System.out.println(to); 
System.out.println(subject); 
System.out.println(context); 
// 确定要发送的邮件服务器的地址 
String mailserver = "tang-429"; 
// 设置邮件的传输协议 
try { 
Properties prop = System.getProperties(); 
prop.put("mail.smtp.host", "tang-429"); // 建立邮件发送的连接 
Session session = Session.getDefaultInstance(prop, null); 
// 创建发送的信息的载体 
Message msg = new MimeMessage(session); 
// 设置相关的邮件属性 
msg.setFrom(new InternetAddress(from)); 
// 点到点的发送 
msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to)); 
msg.setSubject(subject); 
msg.setSentDate(new Date()); 
msg.setText(context); Transport.send(msg); } catch (Exception e) { 
e.printStackTrace(); 
} out.print("发送成功!!!!"); 
out.flush(); 
out.close(); 
} }

Answer 3

ant介绍：与GNU make工具类似的 一种构建工具使用java编写，开放源代码由apache组织负责开发和维护ant build文件：
ant寻找build文件，然后确定该执行任务默认情况下，寻找build。xml文件ant build文件的实例：
1. 基于xml的 所以有xml申明
2. basedir=根目录
3. target ： 执行动作 
javac:如编译 源文件目录和 编译以后的目录
java:<target name="run" depends="compile">
<java classname="classname">
<classpath><pathelemetn path="classes"></classpath> 一个project能够通过<property>元素定义一系列属性
 使用$ {property-name}符号引用属性值、无论多少个target依赖于一个target
 ，该target都只执行一次
target可以像命令行参数一样明确指定
