Tomcat 5.5.0 (yoavs)

> 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)
