Go JavaMail Mail-Send a text message and some problem description

The jar package that needs to be downloaded:

Javamail:http://www.oracle.com/technetwork/java/javamail/index.html

Jaf:http://www.oracle.com/technetwork/java/javase/downloads/index-135046.html

The packages included are: Mail.jar Activation.jar

You have to prepare a mailbox account, just use NetEase's Bar, and then open the SMTP function

Some of the port information about NetEase refer to the following:

Each company is not the same, the use of SSL and not the same is not practical

Using the development and compilation environment is JDK1.4, if you are using the JDK1.5 environment, then your environment needs to modify some things, find Javaee.jar delete inside the mial package, otherwise there will be conflict

Otherwise the error will be:

Java code

2. Exception in thread "main" Java.lang.noclassdeffounderror:com/sun/mail/util/lineinputstream
4. At Javax.mail.Session.loadProvidersFromStream (Session.java:928)
6. At javax.mail.session.access$(Session.java:174)

16. At Javax.mail.Session.getInstance (Session.java:249)
18. At Com.mail.TextMail.main (Textmail.java:)

I'm just pasting the code down here.

Java code

2. Package com.mail;
4. Import Java.util.Date;
6. Import java.util.Properties;
8. Import Javax.mail.Message;
10. Import javax.mail.Session;
12. Import Javax.mail.Transport;
14. Import javax.mail.internet.InternetAddress;
16. Import Javax.mail.internet.MimeMessage;
18. Import javax.mail.internet.MimeUtility;
20. If you use JDK1.4 above the run will appear Exception in thread "main" Java.lang.noclassdeffounderror:com/sun/mail/util/lineinputstream
22. I need you to find Javaee.jar and delete the mail packet.
24. Public class Textmail {
26. public static void Main (string[] args) throws Exception {
28. //Configuration file Object
30. Properties props = new properties ();
32. //Mailbox service address
34. Props.put ( "Mail.smtp.host", "smtp.163.com");
36. //whether to verify
38. Props.put ("Mail.smtp.auth", "true");
40. //Create a session
42. Session session = Session.getinstance (props);
44. //Open debugging, will print the contents of the Mailbox server reply
46. Session.setdebug (true);
48. Message message = New MimeMessage (session);
50. //If the sender does not write to, then the JavaMail 550 Invalid User will appear .
52. //If the sender writes and uses an inconsistent account, the 553 Mail from must equal authorized user will appear
54. InternetAddress from = new InternetAddress ("[email protected]");
56. From.setpersonal (Mimeutility.encodetext ("Java cockroach <[email protected]>"));
58. Message.setfrom (from);
60. InternetAddress to = new InternetAddress ("[email protected]");
62. Message.setrecipient (Message.RecipientType.TO, to);
64. Message.setsubject (Mimeutility.encodetext ("strong brother invited, who dares not from!"  "));
66. Message.settext ("Brother Qiang invited you to visit my blog: http://cuisuqiang.iteye.com/!  ");
68. Message.setsentdate (new Date ());
70. Transport Transport = Session.gettransport ("SMTP");
72. //Specific you use the SMTP address and port of the mailbox, should be in the mailbox to view, if using SSL, NetEase port should be 465/994
74. Transport.connect ("smtp.163.com", "test20120711120200", " test123456");
76. Transport.sendmessage (Message, message.getallrecipients ());
78. Transport.close ();
80. System.out.println ("Send Complete");
82. }
84. }

It is important to note that there

Java code

1. InternetAddress from = new InternetAddress ("[email protected]");

And

Java code

1. Transport.connect ("smtp.163.com", "test20120711120200", " test123456");

The addresses of both mailboxes must be the same, or they will appear

Java code

1. Exception in thread "main" javax.mail.MessagingException: 553 mail from must equal authorized user
3. At Com.sun.mail.smtp.SMTPTransport.issueCommand (Smtptransport.java:1020)
4. At Com.sun.mail.smtp.SMTPTransport.mailFrom (Smtptransport.java:716)
5. At Com.sun.mail.smtp.SMTPTransport.sendMessage (Smtptransport.java:388)
6. At Com.mail.TextMail.main (Textmail.java: $)

You check the Internet is to say that user authentication is not correct, in fact, everyone is in accordance with someone else's code copy, and then modify the user and password, how can not be wrong!

I have this account and password can be used, I am sorry netease!

Since I set up print debugging above, you will see the following in the console:
