Apache Axis Savan/Java moved into the Attic in September 2014. Savan/Java was a Java implementation of WS-Eventing specification. Savan/Java was built on top of Axis2/Java. Therefore by using Savan/Java you could add WS-Eventing capability to Web services hosted using Axis2/Java. Savan/Java was designed as a general publisher/subscriber tool. The arcitecture was designed to abstract the general publisher/subscriber features so that people could support more than one publisher/subscriber mechanisms within the same infrastructure.
The user mailing list, issue tracker and website all remain open, though the issue tracker is read-only. No downloads were made available. See the website at http://axis.apache.org/axis2/java/savan for limited additional information on Savan/Java. Note that the website is incorrect with regards to where the source code is. You can find the source code at http://svn.apache.org/repos/asf/axis/axis2/java/savan/. Also note the issue tracker was https://issues.apache.org/jira/browse/SAVAN.
As with any project in the Attic - if you should choose to fork Savan/Java outside of Apache, please let us know so we can link to your project.
