Apache Tomcat is next to Apache's HTTP server, the second most successful technology the foundation is developing and curating.

The Java Servlet and JavaServer Pages are technologies used in rendering Java-based web pages, and while many think they are a standard, you can still implement different ways how these technologies are run.

Tomcat is Apache's take on the process and aggregates all those technologies into a single server solution for enterprise and small scale environments alike.

The Tomcat server can power large-scale, critical, traffic-heavy Web applications and works across a diverse range of hardware infrastructures.

There are three main versions of the server currently being developed, each targeting different versions of the Java language:
- Tomcat 6.x is for Java 5+, Servlet 2.5+ and JSP 2.1+
- Tomcat 7.x is for Java 6+, Servlet 3.0+ and JSP 2.2+
- Tomcat 8.x is for Java 7+, Servlet 3.1+ and JSP 3.0+


Besides these source code packages offered for download on the Softoware's Scripts section, binary files for OS-specific builds are also available on Softoware

  • Added pluggable password derivation support to the Realms via the new CredentialHandler interface.
  • Added support for TLSv1.1 and TLSv1.2 for APR connector. Based upon a patch by Marcel Šebek. This feature requires Tomcat Native library 1.1.32 or later.

  • The default connector implementation is now the Java non-blocking implementation (NIO) for both HTTP and AJP.

  • The default connector implementation is now the Java non-blocking implementation (NIO) for both HTTP and AJP.

What is new in version 7.0.47:

  • Ported the JSR-356 Java WebSocket 1.0 implementation from Apache Tomcat 8.
  • Deprecated the Apache Tomcat proprietary WebSocket API in favour of the new JSR-356 implementation.
  • Added a drawing board example to the WebSocket examples.

What is new in version 7.0.42:

  • Added support for time to first byte in the AccessLogValve.
  • Corrected a regression introduced in 7.0.39 (refactoring of base 64 encoding and decoding) that broke the JNDI Realm when userPassword was set and passwords were hashed with MD5 or SHA1.

What is new in version 7.0.41:

  • Added a Servlet Filter that implements CORS.
  • Ensure that when Tomcat's anti-resource locking features are used that the temporary copy of the web application and not the original is removed when the web application stops.
  • Added support for the version attribute to the deploy command of the Ant tasks for interfacing with the text based Manager application.

What is new in version 7.0.40:

  • A fix for an information disclosure issue.
  • Various fixes to stop Tomcat attempting to parse text that looks like an EL expression in a JSP document as an EL expression when EL expressions are either not permitted or not enabled.
  • Improved handling and reporting if a ConcurrentModificationException occurs while checking for memory leaks when a web application is being stopped.

What is new in version 7.0.37:

  • Fixed the regression in the JspC tool that is used to pre-compile JSP pages introduced in 7.0.35.
  • Improved handling of ciphers and sslEnabledProtocols options for the BIO and NIO connectors. The behaviour of each connector is now the same. The values provided are pruned to those supported by the SSL implementation and when none of the remaining values are supported a warning is issued and the connector configured with an empty set of options (which essentially disables HTTPS support).
  • Updated to Commons Daemon 1.0.13.

What is new in version 7.0.35:

  • Integrated documentation of Tomcat 7 with Apache Comments System. People can leave their comments when reading the documentation online.
  • Improved detection of JAVA_HOME on OSX.
  • Added support for auto-detection and configuration of JARs on the classpath that provide tag plug-in implementations.

  • Improvements to DIGEST and FORM authentication.

What is new in version 7.0.29:

  • Added support for a default error page
  • The servlet version defined in web.xml no longer determines if Tomcat scans for annotations when the web application starts. This is now solely controlled by metadata-complete element.
  • On web application start, JARs are now always scanned for ServletContainerInitializers regardless of the setting of metadata-complete.

What is new in version 7.0.28:

  • The minimum required APR/native library version required if the APR/native connector is used is now 1.1.24.

What is new in version 7.0.23:

  • Added the ability to start and stop child containers.
  • Cache the results of parsing the global and host level context.xml files to improve start times.
