It provides client application which runs on the users&#8217; desktop and server application which runs on any machine on the network. To start chatting our client should get connected to a server where they can do group and private chatting.<\/p>\n<p>The objective of this project is to develop a java chat application. Let&#8217;s develop an instant messaging solution to enable users to seamlessly communicate with each other. The project should be very easy to use enabling even a beginner to use it.<\/p>\n<h3>Software requirements of the project<\/h3>\n<ul>\n<li>Windows &amp; Higher version (32\/64-bit) license copies as per requirement<\/li>\n<li>Tomcat9 Server<\/li>\n<li>JDBC connectivity<\/li>\n<\/ul>\n<h3>Implementation Languages used to develop the project<\/h3>\n<ul>\n<li>Java<\/li>\n<li>Socket Programming<\/li>\n<li>AJAX<\/li>\n<li>HTML<\/li>\n<li>CSS<\/li>\n<li>JavaScript<\/li>\n<\/ul>\n<h3>Database<\/h3>\n<p>The total number of tables in the database that was identified to build our system is 6.

It is a part of JavaSE (Java Standard Edition). JDBC API uses JDBC drivers to connect with the database.<\/p>\n<p><strong>JSP &amp; Servlets: <\/strong>Java Server Pages (JSP) is a server-side technology that allows development of Web-based applications.<\/p>\n<p>JSP stands for Java Server Page. It is used to create a web application just like Servlet technology. We can think of JSP as an extension to Servlet because it provides more functionality than servlets such as expression language, JSTL, etc.<\/p>\n<h3>Frontend<\/h3>\n<p><strong>HTML (HyperText Markup Language)<\/strong><\/p>\n<p>HTML stands for HyperText Markup Language and it is a standard markup language for creating Web pages. It describes the structure of Web pages.<\/p>\n<p><strong>CSS (Cascading Style Sheets)<\/strong><\/p>\n<p>CSS is a language that describes the style of an HTML document. It describes how HTML elements should be displayed.<\/p>\n<h3>Servlets used in the project<\/h3>\n<p>There are 15 servlets used in this project:<\/p>\n<p><strong>acceptFriendRequest.java<\/strong>: This servlet add friend request in the friend request list.<\/p>\n<p><strong>addFriendRequest.java:<\/strong> This servlet adds the friend request to the user in the friend request list when the user sends the friend request.<\/p>\n<p><strong>AddMessage.java:<\/strong> This servlet adds messages to the message box and shows them to the users.<\/p>\n<p><strong>ApplicationSetting.java:<\/strong> This servlet implements the Serializable interface and sets the number of notifications.<\/p>\n<p><strong>Authenticator.java:<\/strong> This servlet is used to authenticating the user when he login to the system. It checks whether the username and password are correct or not.<\/p>\n<p><strong>CloseAccount.java:<\/strong> This servlet deletes the user account from the database and closes the account.<\/p>\n<p><strong>FriendList.java:<\/strong> This servlet shows the friend list of a user. In this list all the friends that are being added by accepting the friend request.<\/p>\n<p><strong>Logout.java:<\/strong> This servlet is used to logout the user from the application.<\/p>\n<p><strong>MessageList.java:<\/strong> This java file shows the message ists to the user in the message box.<\/p>\n<p><strong>ProfileUpdater.java:<\/strong> This servlet is used to update the user profile like username, name, and password.<\/p>\n<p><strong>removeFriend.java:<\/strong> This servlet removes the friend from the friend list.<\/p>\n<p><strong>RemoveFriendRequest.java:<\/strong> This servlet removes the friend request.<\/p>\n<p><strong>UserAvatar.java:<\/strong> This servlet fetches the images from the images folder and shows them on the webpage of the user profile.<\/p>\n<p><strong>userCreator.java:<\/strong> This servlet creates a new user and adds to the database.<\/p>\n<p><strong>usernameAvailabilityVerifier.java:<\/strong> This servlet checks the username availability at the time of registration. If the user tried to enter the already registered username, then there will be an error message shown that asks the user to choose other usernames.<\/p>\n<h3>Download Project Source Code<\/h3>\n<p>Please download the project: <a href=\"https:\/\/data-flair.training\/blogs\/download-chat-application-project-source-code\/\"><strong>Chat Application Source Code<\/strong><\/a><\/p>\n<h3>Running the Project<\/h3>\n<p>To run this project you need to install the tomcat9 server and apache derby and Java on your system.<\/p>\n<p>1.
