Apache Tomcat 11.0.25

Apache Tomcat is an open-source web server and servlet container designed to run Java-based web applications.

Developed by the Apache Software Foundation, Tomcat supports Java Servlet, JavaServer Pages (JSP), WebSocket, and related technologies. It is widely used by developers to deploy and test Java web applications on Windows and other platforms.

Tomcat is lightweight, configurable, and suitable for development environments as well as production applications.

Key Features

Java Web Application Support – Runs applications based on Java Servlet, JSP, and WebSocket technologies.

Lightweight and Fast – Uses fewer system resources than many full-featured Java application servers.

WebSocket Support – Enables real-time communication for applications that require persistent connections.

Security – Supports SSL/TLS, authentication, authorization, and access control.

Flexible Configuration – Configure ports, connectors, applications, and other server settings through configuration files.

Web Application Deployment – Deploy WAR files directly through the webapps directory or Tomcat Manager.

Cross-Platform – Runs on Windows, Linux, macOS, and other platforms that support Java.

Open Source – Free to use and distributed under the Apache License 2.0.

Installation and Setup

• Download the appropriate Apache Tomcat package.
• Install a supported Java runtime or JDK.
• Set the JAVA_HOME environment variable.
• Extract Tomcat to a directory such as C:\ApacheTomcat.
• Open the bin directory.
• Run startup.bat to start the server.
• Open http://localhost:8080 in a web browser to verify the installation.

How to Use

Start and Stop Tomcat – Use startup.bat and shutdown.bat from the bin directory.

Deploy Applications – Copy a WAR file to the webapps directory to deploy a Java web application.

Change Server Settings – Edit server.xml and other configuration files to change ports, connectors, and server options.

Manage Applications – Use Tomcat Manager to deploy, start, stop, and remove web applications.

Configure Security – Configure users, roles, authentication, and access permissions according to your application requirements.
