Mailing Lists - Guidelines
Before subscribing or participating in any of the mailing lists, we suggest you read and understand the following guidelines:
The POI Developer List
Medium Traffic View, Participate and Subscribe to the Dev List
This is the list where participating developers of the POI project meet and discuss issues, code changes/additions, etc. Subscribers to this list also get notices of each and every code change, build results, testing notices, etc. Do not send mail to this list with usage questions or configuration problems. Use the POI User List or community sites such as Stack Overflow, instead.
The POI User List
Low Traffic View, Participate and Subscribe to the User List
This list is for users of POI to ask questions, share knowledge, and discuss issues. POI developers are also expected to be lurking on this list to offer support to users of POI.
The POI General List
Very Low Traffic View, Participate and Subscribe to the General List
This list exists for general discussions on POI, not specific to code or problems with code. Used for discussion of general matters relating to all of the POI project, such as the website and changes in procedures.
The #apache-poi channel on the irc.freenode.net IRC network is a good place for quick questions. If your questions require a more in-depth answer, you will likely be encouraged to move the question to the mailing list.
Stack Overflow and other communities
There are many POI users in the Stack Overflow community who have asked and answered questions that may be similar to the problem you are facing. Search for the apache-poi tag on Stack Overflow.
Regardless of which community you seek help from, remember to be courteous. Short, working code examples, an explanation of observed and expected behavior, the version of POI you are using, and genuine troubleshooting and research effort on your part go a long way towards getting a helpful answer.
Please read through the FAQ, Quick Guide, How To or Cookbook, and Examples of the POI module that you are trying to use before consulting help. You may also find your question has already been answered on the POI dev or user mailing lists, bugzilla,
