Open Archive 1.0.5 for Openfire 3.6.2 released
Bug fixes and upcoming support in SparkWeb
I've updated Open Archive for the latest version of Openfire and fixed a few bugs. Dele is about to add support for it to the Red5 SparkWeb client.
Open Archive is a XEP-0136 compliant server side message archive for Openfire. It is available as a plugin from here.
To install the plugin just rename the jar to archive.jar, place it into the plugins folder of your Openfire server and enable it in the Openfire console at Server Settings/Archive Settings.
For those interested in the source code have a look at its development site.
Update
Dele has published an updated version of the Red5 plugin that makes use of Open Archive. You can download it from http://red5.4ng.net/red5-0.1.07.zip.
