2025-02-10 Tomcat 10.1.35 Released

The Apache Tomcat Project is proud to announce the release of version 10.1.35 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:

  • Allow readOnly attribute configuration on the Resources element and allow configuration of the readOnly attribute value of the main resources. The attribute value will also be used by the default and WebDAV Servlets.
  • Correct a regression in the fix for bug 69382 that broke JSP include actions if both the page attribute and the body contained parameters. Pull request #803 provided by Chenjp.
  • Expand the options for handling encoded '/' and '\' characters in URLs both in the Connector and when using a RequestDispatcher.

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

2025-02-10 Tomcat 11.0.3 Released

The Apache Tomcat Project is proud to announce the release of version 11.0.3 of Apache Tomcat. This release implements specifications that are part of the Jakarta EE 11 platform.

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:

  • Allow readOnly attribute configuration on the Resources element and allow configuration of the readOnly attribute value of the main resources. The attribute value will also be used by the default and WebDAV Servlets.
  • Correct a regression in the fix for bug 69382 that broke JSP include actions if both the page attribute and the body contained parameters. Pull request #803 provided by Chenjp
  • Expand the options for handling encoded '/' and '\' characters in URLs both in the Connector and when using a RequestDispatcher.

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