Apache Tomcat^®

The Apache Tomcat^® software is an open source implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies. The Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket specifications are developed under the Java Community Process.

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.

The Apache Tomcat Project is proud to announce the release of version 10.0.2 of Apache Tomcat. This release is the first stable release in the 10.0.x series and is targeted at Jakarta EE 9.

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 under development to aid this process.

The notable changes in this release are:

• Add support for using Unix domain sockets for NIO when running on Java 16 or later.
• Add a new StringInterpreter interface that allows applications to provide customised string attribute value to type conversion within JSPs. This allows applications to provide a conversion implementation that is optimised for the application.
• Add peerAddress to coyote request, which contains the IP address of the direct connection peer. If a reverse proxy sits in front of Tomcat and the RemoteIp(Valve|Filter) is used, the peerAddress is likely to differ from the remoteAddress. The remoteAddress is likely to contain the address of the client in front of the reverse proxy, not the address of the proxy itself.

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

The Apache Tomcat Project is proud to announce the release of version 8.5.63 of Apache Tomcat. Apache Tomcat 8.5.x replaces 8.0.x and includes new features pulled forward from Tomcat 9.0.x. The minimum Java version and implemented specification versions remain unchanged. The notable changes compared to 8.5.61 include:

• Add a new StringInterpreter interface that allows applications to provide customised string attribute value to type conversion within JSPs. This allows applications to provide a conversion implementation that is optimised for the application.
• Add peerAddress to coyote request, which contains the IP address of the direct connection peer. If a reverse proxy sits in front of Tomcat and the RemoteIp(Valve|Filter) is used, the peerAddress is likely to differ from the remoteAddress. The remoteAddress is likely to contain the address of the client in front of the reverse proxy, not the address of the proxy itself.
• Escape elements in the access log that need to be escaped for the access log to be parsed unambiguously.
