在Eclipse中使用James Server使用JavaMail

Question

任何人都可以告诉我如何在Eclipse中使用James服务器作为我的服务器和Java？

我想测试下面发布的两个类，但我得到以下错误： 线程“主”的异常javax.mail.AuthenticationFailedException：身份验证失败。

public class JamesConfigTest 
{ 
public static void main(String[] args) 
throws Exception 
{ 
// CREATE CLIENT INSTANCES 
MailClient redClient = new MailClient("red", "localhost"); 
MailClient greenClient = new MailClient("green", "localhost"); 
MailClient blueClient = new MailClient("blue", "localhost"); 

// CLEAR EVERYBODY'S INBOX 
redClient.checkInbox(MailClient.CLEAR_MESSAGES); 
greenClient.checkInbox(MailClient.CLEAR_MESSAGES); 
blueClient.checkInbox(MailClient.CLEAR_MESSAGES); 
Thread.sleep(500); // Let the server catch up 

// SEND A COUPLE OF MESSAGES TO BLUE (FROM RED AND GREEN) 
redClient.sendMessage(
    "blue@localhost", 
    "Testing blue from red", 
    "This is a test message"); 
greenClient.sendMessage(
    "blue@localhost", 
    "Testing blue from green", 
    "This is a test message"); 
Thread.sleep(500); // Let the server catch up 

// LIST MESSAGES FOR BLUE (EXPECT MESSAGES FROM RED AND GREEN) 
blueClient.checkInbox(MailClient.SHOW_AND_CLEAR); 
} 
}

我有相同的javax.mail.AuthenticationFailedException问题。基本上我通过使用命令“deluser blue”删除用户蓝色，然后使用命令“adduser blue blue”再次添加用户来修复它。之后，它的工作。
