About:
Apache Tomcat 9 is an open-source implementation of the Java Servlet, JavaServer Pages, and Java WebSocket technologies. It provides a pure Java HTTP web server environment for executing Java code. This version aligns with the Servlet 4.0 and JSP 2.3 specifications, making it essential for deploying dynamic Java web applications.
Key Features:
  • Implements Java Servlet 4.0 and JSP 2.3 specifications
  • Lightweight and fast core for embedded deployments
  • Robust security manager and realm support
  • Integrated management interface for app deployment
Use Cases:
  • Hosting enterprise-grade Java web applications
  • Developing and testing JSP/Servlet based projects locally
  • Running as an embedded web server in Java applications
Alternatives:
  • Jetty – Jetty is often lighter and more suitable for embedded scenarios, while Tomcat is the industry standard for full enterprise deployments.
  • Nginx – Nginx is a high-performance HTTP server and reverse proxy, but it does not execute Java code natively like Tomcat.
