NetBeans Mailing Lists

Whether you are a user looking for help with the IDE or a developer discussing aspects of the next release, these mailing lists are where it all happens. To subscribe, unsubscribe, browse archives, or for more info on individual lists, please follow the appropriate links below.

New users start here!

  • If you are interested in using NetBeans IDE and need support, at a minimum subscribe to nbannounce and nbusers, the main user and interest lists.

Which other lists should I subscribe to?!

  • If you're interested in developing NetBeans, subscribe to nbdev and , and perhaps some other development lists. If you're heavily involved in development, you may be interested in the build process lists.
  • If you're developing something with a user interface or are interested in usability issues, subscribe to nbui, the usability list.
  • There are some additional per-module lists, i.e. lists hosted on and about a specific NetBeans module or project. These tend to be smaller lists, and obviously much more specialised. It's best to ask about them on nbdev if you're interested in deep-diving on a particular module.
  • We also offer lists for community members interested in NetBeans-related job offers, the netbeans website, and NetBeans evangelism - see the community-related lists.
  • You can also talk to Java developers in French, Russian, Portuguese, Japanese or Chinese, see lists in your language.
  • See the license page for pointers on where to discuss the license.

Forums and Newsgroups

  • Forum Access

    If you prefer discussion forums to mailing lists, all NetBeans mailing list messages are archived to a fully functional forum. Browse and search archived e-mails, posts to the mailing lists are propagated to the forum, and vice versa. Here's the overview of all NetBeans Forums hosted on Nabble.

    You need to register with Nabble to use this service. In addition, messages posted via the forum will be moderated by us unless you sign up to the list of non-subscribers allowed to post. To save your messages being moderated, and to save the moderators work, please contact the list owner and request this.

    Note : SourceCast (the application that hosts netbeans) does not include forum support yet, so this service is supplied by the Free Hosted Public Forums service by Nabble.

  • Usenet / NNTP access

    Alternatively, if you prefer USENET news to mailing lists, all top-level lists are gated to news - posts to the lists are propagated to the newsgroups, and vice versa. Point your newsreader at news.gmane. Note that the group names are not exactly the same as the mailing list names (to match Gmane conventions), though most are quite obvious. Use your client to search for "netbeans" groups - e.g.

    To post to the lists via NNTP, you will need to reply to the authorisation request that GMane will send. In addition, messages posted via NNTP will be moderated by us unless you sign up to the list of non-subscribers allowed to post. To save your messages being moderated, and to save the moderators work, please contact the list owner and request this.

    Note : SourceCast (the application that hosts netbeans) does not include NNTP support, so this service is supplied by the free mailing list to NNTP gateway Gmane.

Unsusbscribing From a Mailinglist

Unsubscribe links are included on each of the list pages above, right beside the subscribe links. If you are having trouble :

  • Don't mail "unsubscribe me" or "help" to the list you're trying to unsubscribe from!
  • Check the Mailing List FAQ and the How to Unsubscribe pages for help.
  • If you still can't unsubscribe, contact the list owner - details in the FAQ.

List Etiquette

While everyone's input is always welcome, the top-level lists are quite high-volume, and putting a little effort into messages you post will mean the difference between getting a response or getting ignored. Please try to follow general common sense list etiquette when posting! A few tips :

  1. Don't post the same message to more than one list - pick a list and post just there. If it is the wrong place someone will let you know and suggest an alternate.
  2. Do not reply to a message and change the subject completely, since threaded mailreaders show it in a weird place; send a new message when starting a new thread.
  3. Read Eric Raymond's How To Ask Questions The Smart Way guide.
  4. Please trim the original text in your reply. Include the very minimum of the original text that directly relates to your reply. Worst is the habit of making a one line response that is followed by the original e-mail in its entirety.
  5. Similarly, if you are making a point by point reply, where you include some original text and then follow it with your reply, and then do the same with the next point, please make it easy to find your replies. If you've included 40 lines of original text and followed it by a one line reply, then go on to another 40 lines of original text, it is very hard to find your reply in there. If you must include the full 40 lines of quoted text, perhaps add a blank line after it before your reply. Add, perhaps, two blank lines after your reply before continuing on with original text again.
  6. Please do not use styled text in your e-mail. Your choice of font, font size, font colour, etc. can make your e-mail virtually unreadable for others! Please just use plain text unless there is a compelling reason otherwise. If you simply do not style your text, everyone's e-mail readers will style it the way they want, ensuring it will be readable and pleasing to the eye everywhere.
  7. Similarly, please don't send HTML messages! Readability, the size of messages, and security are just a few of the reasons not to send HTML mail. A good description of these and other problems, as well as instructions on how to disable HTML mail in many common mail clients is available.

    HTML attachments are fine of course!

A note about mail filters

As several of the lists are high volume, a few conventions are in use to aid sorting and filtering. The mailing list software automatically prefixes the Subject: fields of all NetBeans lists with the name of the mailing list, so for example msgs to the nbdev list have subjects beginning with [nbdev].

It is also common for list subscribers to add some kind of topical label to the subject field, like [Stable3.1 Release], to track different, but related, threads. This is of course entirely up to the individual.
