Java Implementation Send mail tool

Java implementation of the ability to send mail: First need to import Mail.jar;
Then you need to write the sending method:
1, the Mailbox Send Packaging tool class:

Each JavaMail-based application has at least one session but can have any number of sessions.                 the//session class defines the global and message-related properties of each user. This property describes how the room machine and the server communicate information.                 //authenticator is also an abstract class, and you need to write your own subclass of ready-made applications.

The message type (MimeMessage is one of the types) is used.                 The //Message object stores the e-mail messages that we actually send, and the message object is created as a MimeMessage object and needs to know which JavaMail session should be selected.

2, the mailbox sends the information entity class:

Package com.wxjiameng.utils; Public classEmailparaform {//Number    PrivateString ID;//Sender    PrivateString Tfrom;//recipients, separated by semicolons    PrivateString Tto;//Theme    PrivateString Ttitle;//Content    PrivateString tcontent;//Send mail server    PrivateString Stmphost;//Accept mail server    PrivateString Pophost;//Agreement    PrivateString Protocol;//Whether certification is required    PrivateString Needauth;//Verify class name    //private String authclassnm;    PrivateString Isdebug;//CC, separated by semicolons    PrivateString TCC;//Dark send, separated by semicolons    PrivateString TBCC;//Multiple attachments separated by semicolons    PrivateString fileattachments;//user name    PrivateString UserName;//Password    PrivateString password;//proxy server IP    PrivateString Agentip;//Proxy server port number    PrivateString Agentport;//weblogin Configuration javamail: You need to specify the Jndi name to retrieve    PrivateString JNDINM;//Receive Protocol    PrivateString Pprotocol;//Send mail server port    PrivateString Tport;//Receive mail server port    PrivateString Pport;//set Get Method}

The following exception occurs when you use it:

Need to check the sender's mailbox whether to open POP3/SMTP permissions, open can send success; I do not understand the message to me, learn from each other!
