I have written a custom ch.ivyteam.ivy.security.ISessionExtension so that I get informed whenever someone is authenticated on the Axon.ivy Engine. I need a mechanism to register this extension on every server startup so that I can be sure that the extension still works after a reboot of the engine. How can I do that?

With 7.0 and higher:

You need to make an extension bundle / Eclipse plugin to extend the Engine / Designer. How to do this see the Concept chapter in the Designer Guide. The Extension Point is still the same as before: ch.ivyteam.ivy.server.IServerExtension

Follow these steps to attach your session listener when the engine starts:

  • Move your ISessionExtension implementation into an own ivy-project that contains nothing but the extension
  • Implement an ch.ivyteam.ivy.server.IServerExtension that can be used to start/stop your extension. Typically in here you register your code against a Manager of the ivy core engine.
  • Convert your ivy-project into a PDE plugin project. Java Perspective -> Project context menu -> Configure -> convert to Plugin Projects
  • Add a META-INF/MANIFEST.MF file.
  • Add the IServerExtension (will create a plugin.xml file in the root of the project). To do open the MANIFST.MF, tab 'extensions' -> add -> IServerExtension
  • Set your own ServerExtension as 'class' of the IServerExtension
  • Export -> JAR -> include 'src, META-INF/MANIFEST.MF, plugin.xml'
  • Put the JAR to your engine under lib/patch
  • Start the engine. The name of your extension should appear in the list of started services.


  • tested on Axon.ivy 6.5
  • the simplified registration via extension point should work since Axon.ivy 6.1
