This project is a java tutorial on how to make a logging mechanism for a multi-threaded application which may have more than one method of storing logging information.

The mechanism is implemented as a singleton which is a logging interface. This interface is agnostic and doesn't care about what method is actually being used to store the logging data. The program could be writing to a file, displaying in some GUI text area, writing to a database, or streaming over a network socket.

With this interface, the user doesn't need to continually change their code in order to implement a new logging method.

This is accomplished using Java's Observer/Observable mechanism so that one (or more) log message producers, can send log messages to one (or more) log message consumers. The method supports multiple log levels (debug, error, etc.).

A video on Creating and using a jar file in Eclipse is OUT NOW!!!! You can checkout the video here.

Websocket is used to develop two way communication between server and browser. For example, in a chat application, if a user sends a message to a different user, the the application sends that message to the server first and the server informs the application of the second user . If we don’t use websocket, the application or the client will have to pull the server data continuously for any new updates.

In Sprint Boot, we can easily create a websocket application. In this tutorial, I will show you how to create a websocket server in Spring boot. We will learn how to connect and disconnect from a socket server and how to send a simple text message. The client will subscribe to the server, it will accept a string and push a separate string to the subscriber client.
