The Apache Tomcat team announces the immediate availability of Apache
Apache Tomcat 10 is an open source software implementation of the
Jakarta Servlet, Jakarta Server Pages, Jakarta Expression Language,
Jakarta WebSocket, Jakarta Authentication and Jakarta Annotations
Applications that run on Tomcat 9 and earlier will not run on Tomcat 10
without changes. Java EE 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 compared to 10.1.2 include:
- Refactor WebappLoader so it only has a runtime dependency on the
migration tool for Jakarta EE if configured to use the converter as
classes are loaded.
- When an HTTP/2 stream was reset, the current active stream count was
not reduced. If enough resets occurred on a connection, the current
active stream count limit was reached and no new streams could be
created on that connection.
- Update to Commons Daemon 1.3.3
