通过gmail smtp。 认证课程：
package br.com.projekt.gui;
import java.util.Arrays;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
class SimpleAuth extends Authenticator {
public String username = null;
public String password = null;
Mail email = new Mail();
public SimpleAuth(String user, String pwd) {
username = user;
password = pwd;
}
@Override
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication ( Mail.mail.getText(),Arrays.toString(Mail.pass.getPassword()));
}
}
通过jTextFields我提供了信息，但是因为我在运行时有一个空字段而得到了错误！
