Apache Tomcat

The Apache Tomcat® software is an open source implementation of the Jakarta Servlet, Jakarta Server 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.

2021-04-06 Tomcat 10.0.5 Released

The Apache Tomcat Project is proud to announce the release of version 10.0.5 of Apache Tomcat. This release implements specifications that are part of the Jakarta EE 9 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:

  • Fix a regression in 10.0.4 that meant that an error during an asynchronous read broke all future asynchronous reads associated with the same request instance.
  • Prevent concurrent calls to ServletInputStream.isReady() corrupting the input buffer.
  • Update the packaged version of Tomcat Native to 1.2.27 to pick up binaries built with OpenSSL 1.1.1k.

Full details of these changes, and all the other changes, are available in the Tomcat 10 changelog.
