call failed with status BadNotImplemented

[francy328]

I've tried to add namespaces to the example server, like as been done in https://github.com/kevinherron/machine-example/tree/master, (just changed some xml file).
I start the server and when I connect with UaExpert I see what I'm expecting to view, and that is really fantastic:

But when I call I method like GetLatestResult i get:

On the server side no log at all, So my question is Where to start in order to implement that method? Should I define a Listener on some node? and if that is true where I can find an example?

[kevinherron]

You need to get that Node instance somehow and install an InvocationHandler on it.

Alternatively, you could override the call implementation of your AddressSpace, and try to handle the CallMethodRequests yourself, figuring out which object/method is which based on the ids in the requests.

Or if it's a ManagedAddressSpace subclass, override getImplementationHandler.

Thx Kevin for replay;

I'm trying to figure out as you indicated but no success so far!

for the First indication

I know I have my node in the server, but how I can find it?

I've tried:

       NodeId objectId2 = NodeId.parse("ns=2;s=JoiningProcessManagement");
   	server.getAddressSpaceManager().getManagedNode(objectId2);

but the last line dosn't give me an object like i have in:

 UaObjectNode myObject = (UaObjectNode) getNodeFactory().createNode(
                newNodeId("HelloWorld/MyObject"),
                objectTypeNode.getNodeId()
            );

in order to associate an hander to it like this:

List<UaMethodNode> listMethod = myObject.getMethodNodes();
            listMethod.get(0).setInvocationHandler(sqrtMethod);

in the last snippet myObject is of type UaObjectNode.

for the second indication:
how I can get addressSpace ? on the server side there is server.getAddressSpaceManager() but I think is not the same

for the third indication:
Yes the class ModeledAddressSpace is a subclass of ManagedAddressSpace
but there is not method called getImplementationHandler, may be you say getInvocationHandler?

You might have to cast it? If it got created as a UaObjectNode, or subclass of, it'll be in one of the AddressSpaces as one.

Keep track of them as you create them.

Yes, that's what I meant.

If I'm going to do:

NodeId objectId = NodeId.parse("ns=8;i=72");
UaObjectNode myObject = (UaObjectNode) getNodeManager().get(objectId);

myObject is always null, but I know there is that node because if I'm goingo to see with UaExpert I'll find;
I do not know if I can use getNodeManager to find out a node, or if I'm going to make a mistake on NodeId.parse

[francy328]

I'm a stupid one there are two mistake:

1. The position where I put that snippet was wrong (it was before the startuptask) so when addNode to getNodeManager was't yet called;
2. and the second one is that I used get and not getNode, I solved in this way:

`NodeId objectId8 = NodeId.parse("ns=8;i=72");
Optional on = server.getAddressSpaceManager().getManagedNode(objectId8);

	UaObjectNode myObject1 = (UaObjectNode) on.get();
	List<UaMethodNode> listMethod = myObject1.getMethodNodes();
	 
	listMethod.forEach((n) -> System.out.println(n.getBrowseName()));
	
	//trovo il metodo  
	NodeId method = NodeId.parse("ns=8;i=97");
	Optional<UaNode> on1 = server.getAddressSpaceManager().getManagedNode(method);
	 UaMethodNode methodNode = (UaMethodNode) on1.get();
	 
	 AbortJoiningProcess aJp = new AbortJoiningProcess(methodNode);
	 listMethod.get(0).setInvocationHandler(aJp);
	 listMethod.get(1).setInvocationHandler(aJp);`

Now I have another problem!!!
