This document is a living list of the action items related to the
current development of the Catalina servlet container architecture
for Tomcat 4.0.
The columns in this report contain the following information:
- Priority - A sense of how important the Tomcat development
community feels it is to address this issue in the short term.
- Action Item - Concise description of the action item
to be completed. Where relevant, Java package names of the
primary classes involved are listed in [square brackets]
- Volunteers - Names and EMAIL addresses of those developers who
have volunteered to assist in the design, implementation, testing, and
documentation of this action item's changes to Tomcat.
Additions to, subtractions from, and changes to the action items listed
here should be discussed and approved on the TOMCAT-DEV mailing list, as
described on the
Decision
Making page on the Jakarta Project web site. Developers can nominate
themselves to work on particular action items by asking a Committer to add
their name and EMAIL address to those items. The developers working on each
item should discuss and agree upon the approach to be used for implementing
the item's changes to the project source code and documentation, prior to
completing those changes. Such discussions should take place on the
TOMCAT-DEV mailing list so that everyone can stay apprised of what is going
on, or chime in if they want to contribute ideas and suggestions.
For convenience, the action items have been organized into general
categories, which are presented in alphabetical order. The following
categories of actions are currently identified:
Architecture
Priority |
Action Item |
Volunteers |
Medium |
Define extensions (if necessary) to the Catalina architecture to
support distributed, load-balanced, servlet containers. |
Craig McClanahan |
Medium |
Improve the manageability of Catalina components by adding
support classes and interfaces as necessary to meet the requirements
of the Java Management Extensions (JMX) specification. |
Remy Maucherat |
Medium |
Improve the manageability of Catalina components by adding
support classes and interfaces as necessary to meet the requirements
of the Avalon framework. |
--- |
Low |
Define and provide default implementations for logging of server
related events and messages, as opposed to the application-level
logging provided by Logger implementations.
[org.apache.catalina.syslog?] |
--- |
Connectors
Priority |
Action Item |
Volunteers |
High |
Design and implement a high-performance Connector implementation
that interoperates with the existing mod_jk
infrastructure of Tomcat 3.2, to provide either in-process or
out-of-process servlet/JSP support for Apache (2.0 required for
in-process), Microsoft IIS, Netscape iPlanet, and AOLServer.
[org.apache.catalina.connector.modjk] |
Pier Fumigalli |
Core Servlet Engine Functionality
Priority |
Action Item |
Volunteers |
High |
Implement the Tomcat 3.x feature of being able to configure a
security policy for each deployed web application. |
Glenn Nielsen |
Medium |
Implement the optional web application environment support
described in Section 9.9 of the Servlet API Specification Version 2.2,
and Chapter 5 of the Java2 Platform Enterprise Edition Version 1.2
Specification. |
--- |
Server Administration Functionality
Priority |
Action Item |
Volunteers |
Medium |
Design and implement a web application providing server
management support for a running Catalina installation.
[org.apache.catalina.admin]
| John Shin |
Medium |
Improve the ease of installation (and the quality of installation
documentation) through the use of installer program technology. |
--- |
Low |
Port out-of-the-box functionality to install Catalina as a "service"
under Microsoft NT, based on the existing code used for Tomcat 3.2.
[org.apache.catalina.startup] |
--- |
Servlet Provided Functionality
Priority |
Action Item |
Volunteers |
Low |
Design and implement a servlet that supports interpretation of
web-server-like "server side include" directives, typically
found in *.shtml files.
[org.apache.catalina.servlets] |
--- |
Low |
Design and implement a servlet that supports interpretation of
<servlet> directives, typically
found in *.jhtml files.
[org.apache.catalina.servlets] |
--- |
Low |
Design and implement a CGI emulation servlet for
Catalina. [org.apache.catalina.servlets] |
Martin T. Dengler |
Session Management Functionality
Priority |
Action Item |
Volunteers |
Medium |
Design and implement a Manager implementation that
supports swapping of active, but idle, sessions to persistent
storage via a suitably configured Store implementation.
[org.apache.catalina.session] |
--- |
Medium |
Finish design and implementation of a filesystem-based
Store implementation. [org.apache.catalina.session] |
--- |
Medium |
Design and implement a JDBC-based Store implementation.
[org.apache.catalina.session] |
--- |
Medium |
Design and implement a Store implementation based on
JavaSpaces and/or IBM's TSpaces frameworks. |
Jim Cook |
Utility Component Functionality
Priority |
Action Item |
Volunteers |
Medium |
Design and implement a Realm implementation that accesses
authentication and role information from a JNDI-accessed directory
server. [org.apache.catalina.realm] |
James W. |
Medium |
Design and implement a Resources implementation that
interacts with a web server Connector (such as the one for Apache)
to access web server resources through the connection protocol,
rather than as disk files. |
--- |
Low |
In LoggerBase , add support for optional "decoration"
of logged messages with XML elements.
[org.apache.catalina.logger] |
--- |
Valve Provided Functionality
Priority |
Action Item |
Volunteers |
Medium |
Design and implement support for SSL/TLS based authentication.
[org.apache.catalina.authenticator] |
John Shin |
Medium |
Extend the authentication implementations to operate
at the Engine or Host level of the
Container hierarchy, not just the Context
level, to provide "single sign on" support. |
--- |
Low |
In AccessLogValve , implement parsing and pattern matching
for more complete emulation of Apache's custom log generation
capabilities. |
--- |
Low |
Design and implement a valve that provides functional support
corresponding to the Apache server directives Alias
and AliasMatch that support mapping of document trees
to be mapped to different locations within the document root.
[org.apache.catalina.valves.AliasValve] |
--- |
Low |
Design and implement a valve that provides functional support
corresponding to the Apache server directives Redirect ,
RedirectMatch , and RedirectTemp that
support temporary or permanent redirection of matching requests
to different locations.
[org.apache.catalina.valves.RedirectValve] |
--- |
Low |
Design and implement a valve that provides functional support
similar to the Apache server Rewrite family of
directives that support transformations on the request URI.
[org.apache.catalina.valves.RewriteValve] |
--- |
Low |
Improve security of the HTTP DIGEST authentication implementation.
[org.apache.catalina.security] |
