As the name of the extension suggests, this module provides two features for the eXist-db database/application server:
With the document replication feature it is possible to automatically and transparently synchronize documents and document updates into a network of eXist-db instances.
The messaging feature allows the exchange of messages with an enterprise message broker. Both features share the set of (JMS) configuration parameters.
Both features use Java Message Service (JMS) technology for the reliable transport of the data. The extension has been developed with the excellent Apache ActiveMQ open source messaging server.
A binary distribution is available via the releases section.
Build instructions are available here. Please report issues with the extension specific issue tracker but I prefer to accept pull requests!
Instructions on how to install the extension can can be found on the Installation page. Also consult the compatibility page to verify your system/database configuration.
How to get started with ActiveMQ is described here.
The extension has been developed and tested with recent eXist-db builds (built from git/develop). The extension can either work or not work with the latest released version (2.1 at the time of writing). The reason for a potential compatibility is a recent (incompatible) change in the Trigger classes.
Please alse note that this extension requires significant knowledge about JMS, ActiveMQ and related technologies. I'd recommend to buy a book about these subjects or contact eXist Solutions GmbH for assistance and advice.
