我用的时候有错误~~前面部分我是这样写的，（后面的就是你给的）
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class sendMailtest{
    public static void sendMail(String eMail,String subject,String content) throws Exception {
String smtp = "smtp.163.com";
String sender = "[email protected]";
try{
              Properties mailProps = new Properties();
     mailProps.put("mail.smtp.host",smtp);  
     mailProps.put("mail.smtp.auth","true");
     mailProps.put("mail.smtp.user","netwebs");
     mailProps.put"mail.smtp.password","password");
我从[email protected]这个邮箱发，这个信箱的user是netwebs，密码是password（现在是假的了~~呵呵），还是发到[email protected]，出现错误“java.lang.NoClassDefFoundError:javax/activation/DataSource”
我的环境是jdk1.4.2，javamail是1.3的，给解决一下啊~~
