version

Preface

This is the Changelog for Tomcat 5.5.x, which was branched based on Tomcat 5.0.27. For changes in Tomcat version 5.0.x, which preceded version 5.5.0, please see The Tomcat 5.0.x Changelog. As maintenance releases are cut on the 5.0.x branch, most fixes will be ported into a 5.5.x release and noted both here and in the above Changelog. However, bugs fixed in Tomcat 5.0.28 and earlier are noted only in the above changelog.

General

Many updated and fixed JavaDocs. (yoavs)

Designed and tested Tomcat on J2SE 5.0 (aka JDK 1.5). (everyone)

Bundled Eclipse JDT (new dependency) to allow Tomcat to run on a JRE only, i.e. no JDK required. (remm)

Repackage commons-dbcp and its dependencies as a sigle smaller WAR, with renamed packages. (remm)

Removed dependencies on commons-digester, commons-beanutils, and commons-collections. The relevant digester functionality is now merged in tomcat-util. (remm)

Catalina

Removed usage of org.apache.catalina.Logger, increased usage of commons-logging everywhere. (remm)

Refactored classloader code to better handle JAR and general resource locking. (remm)

Written JMX-related code to play nicely with J2SE 5.0 built-in JMX abilities. (remm, costin)

Extensively profiled and optimized the server startup performance as well as the request mapping and processing pipeline. (remm)

The container will now always process a /META-INF/context.xml resource, unless the webapp has a specified external context file. (remm)

New default configuration mechanism for web applications, replacing DefaultContext. This uses a shared context file located in conf/context.xml. (remm)

Revamped deployer, alloying full hotdeploy (note: on Windows, this requires the anti file locking features). (remm)

Remove verbosity from the JNDI resources configuration, by allowing arbitrary attributes on the Resource element. (remm)

Simpler Valve interface, to allow smaller stack traces and reducing the amount of method calls. (remm)

Coyote

Jasper

Eclipse JDT is now the default Java compiler in Jasper. Source dependencies are now loaded from the container classloader, and compilation times are much faster. (remm)

Jasper development mode should now have acceptable performance for heavily accessed pages. Precompiling JSPs is still significantly more efficient, however. (remm)

Cluster

Webapps
