Apache Tomcat Mailing Lists

Before you can send a message to one of the Tomcat lists, you must subscribe to that list. If you try to send a message to a list from an e-mail address that is not subscribed to the list, it will be rejected.

All messages to the Tomcat lists are filtered for spam. To avoid your valid message being marked as spam:

  • send your message in plain text, not HTML;
  • include a subject.

The following lists are available:

tomcat-users
User support and discussion
taglibs-user
User support and discussion for Apache Taglibs
tomcat-announce
Low volume announcements including all releases and security vulnerabilities
tomcat-dev
Development mailing list, including commit messages

Users should consider subscribing to the User Support and the Announcements mailing lists. The Developer list is for people interested in helping with the development and debugging of the server.

Formatted archives are available in several places including the Apache Mail Archives, MARC, Nabble, and MarkMail. The raw mbox files are also available.

You can also use the mail-to-news gateway offered by GMANE to access most of the lists with a news reader.

tomcat-users

The list listed here is the only place that configuration and how-to questions belong, ever. Every day, users become frustrated, not with Apache Tomcat, but how nobody will help them understand how to get started. 95% of the time, it's not for lack of helpers, but for lack of effort and well stated questions.

Before you go further, please read Eric S. Raymond and Rick Moen's explanation of "How To Ask Questions The Smart Way". If you follow their advice, you will discover that these forums have dozens of helpers ready to provide you with guidance on using Apache Tomcat! Note: Do not send your Apache Tomcat questions to Eric or Rick themselves!

Important:

  1. When asking questions on the list, please state your exact Tomcat version (which is three numbers, 7.0.x or 6.0.x), your operating system, and essential bits of your configuration.
  2. Note, that Tomcat Documentation is provided on this site (see the links at the left) and is searchable (see an input box above). Add "Tomcat 7.0", or "Tomcat 6.0" to your query to refine your results. The tomcat-users mail list archives (links are below) are also searchable.
  3. The FAQ and How To pages are available at the Tomcat Wiki.
  4. Usage of these mailing lists is subject to the Public Forum Archive Policy.
  5. To post a question, start a new thread by sending your mail to the "Posting questions" address below. Do not reply to an existing e-mail. To be able to post to the mailing list, you have to be subscribed.
  6. When replying, please write your text below the quoted one. Top-posting is bad.
  7. Please format your messages as plain text, not HTML. Do not send attachments, as they are likely to be removed and ignored by the mailing list server.
