Apache Tomcat

Apache Tomcat is an open-source implementation of the Jakarta Servlet, Jakarta Server Pages, and other Jakarta EE technologies, providing a pure Java HTTP web server environment for running Java code. The Tomcat Manager application exposes an HTTP API for deploying, managing, and monitoring web applications. The JMX Proxy Servlet provides programmatic access to JMX MBeans for server diagnostics and configuration. Governed by the Apache Software Foundation.

Apache Tomcat publishes 7 APIs on the APIs.io network, including Applications API, Configuration API, Diagnostics API, and 4 more. Tagged areas include Application Server, Java, Servlet Container, Web Server, and Open Source.

The Apache Tomcat catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Apache Tomcat’s developer surface includes authentication, documentation, changelog, and 10 more developer resources.
