Newbie issues with XEP

Hello,

I'm brand new to InterSystems and their products.

Doing some research for my job, I've found myself going through the learning paths Connection Java Application to InterSystems(https://learning.intersystems.com/course/view.php?id=879).

Working through the proposed demos (https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl… and https://github.com/intersystems/quickstarts-java) I cannot get the methods deleteExtent, importSchemaFull and getEvent to work on the EventPersistor.

I keep getting this error

I've found that the tag <PROTECT> refers to this :

I'm creating a connection with SuperUser, I've also tried _SYSTEM. The installation of the IRIS instance is on the same machine as the java app. Interacting with the database via JDBC and NativeAPI works fine.

If anyone has any helpful debugging tips, it would be greatly appreciated. If I can provide any other info please let me know?

Thanks,

Alex
