How to register my code that runs on every engine startup?

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

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
