Apache Tomcat^®

The Apache Tomcat^® software is an open source implementation of the Jakarta Servlet, Jakarta Pages, Jakarta Expression Language, Jakarta WebSocket, Jakarta Annotations and Jakarta Authentication specifications. These specifications are part of the Jakarta EE platform.

The Jakarta EE platform is the evolution of the Java EE platform. Tomcat 10 and later implement specifications developed as part of Jakarta EE. Tomcat 9 and earlier implement specifications developed as part of Java EE.

The Apache Tomcat software is developed in an open and participatory environment and released under the Apache License version 2. The Apache Tomcat project is intended to be a collaboration of the best-of-breed developers from around the world. We invite you to participate in this open development project.

Apache Tomcat software powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations. Some of these users and their stories are listed on the PoweredBy wiki page.

The Apache Tomcat Project is proud to announce the release of version 11.0.0 of Apache Tomcat. This release is targeted at Jakarta EE 11.

Users of Tomcat 10 onwards should be aware that, as a result of the move from Java EE to Jakarta EE as part of the transfer of Java EE to the Eclipse Foundation, the primary package for all implemented APIs has changed from javax.* to jakarta.*. This will almost certainly require code changes to enable applications to migrate from Tomcat 9 and earlier to Tomcat 10 and later. A migration tool is available to aid this process.

The notable changes in this release are:

• Multiple fixes and improvements for WebDAV
• Improvements to the recently adding request/response recycling for HTTP/2
• Improve the stability of Tomcat Native during GC

Full details of these changes, and all the other changes, are available in the Tomcat 11 changelog.

The Apache Tomcat Project is proud to announce the release of version 10.1.31 of Apache Tomcat. This release implements specifications that are part of the Jakarta EE 10 platform.

Applications that run on Tomcat 9 and earlier will not run on Tomcat 10 without changes. Java EE based applications designed for Tomcat 9 and earlier may be placed in the $CATALINA_BASE/webapps-javaee directory and Tomcat will automatically convert them to Jakarta EE and copy them to the webapps directory. This conversion is performed using the Apache Tomcat migration tool for Jakarta EE tool which is also available as a separate download for off-line use.

The notable changes in this release are:

• Multiple fixes and improvements for WebDAV
• Improvements to the recently adding request/response recycling for HTTP/2
• Improve the stability of Tomcat Native during GC

Full details of these changes, and all the other changes, are available in the Tomcat 10.1 changelog.
