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.

Environment

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

Sample project

ivy project with SessionExtension and the ServerExtension: SessionExtensionSample_65.iar
compiled, exported JAR to run with an ivy engine: SessionExtensionSample.jar
