Hi,

Generally we recommend using the createInstance of NodeManagerUaNode, but for Property it is a bit special since SDK handles them separately thus there is no direct PropertyType class (compared to the other codegenerated ones where SDK does have a class based on the OPC UA type).

You can either use the “pre-codegen style”:

or the createInstance works as well, but you must use NodeId based version of that:

The lines assume run within com.prosysopc.ua.samples.server.MyNodeManager.createAddressSpace() i.e. no exception handling etc. and they refer the MyLevel UaNode constructed earlier in the method.

For other reference types you would use UaNode.addReference methods (it can also be used for adding Property as that is just ReferenceTypeIdentifiers.HasProperty).
