Apache Tomcat is a servlet container and application server that implements the Jakarta Servlet, Jakarta Pages, Jakarta Expression Language, and Jakarta WebSocket specifications.
The tool solves the problem of running Java web applications by providing a runtime environment that handles HTTP requests, manages servlet lifecycle, and processes dynamic web content. It operates as an open-source implementation of the Jakarta EE Platform specifications, allowing developers to deploy and execute Java-based web applications without building a server from scratch.
Tomcat suits organizations running traditional Java web applications, particularly those already invested in the Jakarta EE ecosystem. It is appropriate for mission-critical applications across diverse industries and scales from small deployments to large-scale systems. The project maintains multiple major versions with separate download and documentation pages, allowing teams to choose the version that aligns with their Jakarta EE specification requirements and compatibility needs.
The project operates as a collaborative open-source effort under the Apache License. Development occurs in a participatory environment with community involvement encouraged through multiple channels including dedicated mailing lists for users, announcements, and bug reporting. The tool is actively maintained across multiple major versions, each with its own documentation and release management, indicating sustained long-term support and ongoing development activity.
