The POP3 protocol (Post Office Protocol) is used to receive emails. The third frequently used version is POP3. It uses the port 110. Through the POP protocol, you can delete or download your emails to your local computer after logging on to the server. It is an offline protocol standard.

A lot of code is generated after the project is created. It is basically a configuration file. During seam development, you do not need to modify the configuration file all day long. Write pages. xml or faces-config.xml at most. The structure of the folder generated by seam is as follows:

Resources folder. XXXX-ds.xml. Is used to store the data source configuration file.

information like a mail server, username, password, and so on.The session constructor is private, and you can use the Getdefaultinstance () method to obtain a single default session that can be shared: Properties Props = new properties ();Fill in some informationSession session = Session.getdefaultinstance (props,null); Alternatively, you can use the getinstance () method to create a unique session such as: Properties Props = new properties ();Fill in some informationSession session = Session.g
, and so on. The session object builds the transport and store objects that are used to send and receive messages based on this information, and provides information support when creating a message object for the client.

Start Tomcat. Then enter the URL http://localhost/examples/servlet/HelloWorldExample. This will redirect you to the CAS login screen. The default authenticator only requires that you provide the same string for the user name and password, for example, to enter a demo in two domains. Then, you are redi
you manually set up an additional token, then you do not need to attach this token.
(2) header key is usually Authorization, if you are not this, you can modify.
(3) If you need to refresh token when encountering such as 401 not authorised, you can use authenticator, which is a specially designed interceptor that asks for access to processing when the validation error occurs:

5, use the Javax.mail.Transport tool class to send mail.
Here is the code I encapsulate, and the comments are more detailed.

First, the Mailauthenticator class is established and inherits from the Javax.

Even if the picture is good, as long as it runs for a while, it will become invisible sooner or later, and the card will become stuck, the crash will crash, and the hell will die. What's more, once OpenGL is used in Java, even the only advantage of flash, the image effect, will no longer exist. For example, Java online games in the famous
