thanks it works!!

just adding:

List<UaMethodNode> listMethod = myObject.getMethodNodes();

listMethod.get(0).setInvocationHandler(sqrtMethod);

UaMethodNode mN = listMethod.get(0);

mN.setInputArguments(sqrtMethod.getInputArguments());

mN.setOutputArguments(sqrtMethod.getOutputArguments());

mN.setInvocationHandler(sqrtMethod);

after UaObjectNode myObject = (UaObjectNode) getNodeFactory().createNode

thanks really

I think your new issue is that you have tried to install the invocation handler on the method that is part of your custom object type definition.

Instead, after creating a new instance of "MyObject", find the new method node attached to it, and install the invocation handler on that new node instead.

Good morning Kevin,

thanks very much for your reply;

I was able to solve the issue for what i send the mail, even if I do not understand why, I just changed the reference, as indicated in the picture:

methodNode.addReference(new Reference(

methodNode.getNodeId(),

//Identifiers.HasModellingRule,

//Identifiers.HasComponent,

//objectTypeNode.getNodeId().expanded(),

Identifiers.HasModellingRule,

Identifiers.ModellingRule_Mandatory.expanded(),

false

));

And I get what I want that is an object "MyObject" and a method as a child under it "SendJoinprocess"

Now I have a different problem. The method defined under MyObject does not works at all (the code on method SendJoinProcess is the same as in the method sqrt(x)).

and if a make a call:

while I'm going to aspect:

So I'm not able to understand, why the method under QualityServer works well, and the method under MyObject does not work at all; In attached the class ExampleNamespace

What have you tried so far?

The example adds a method as a child to a folder object, which is conceptually the same thing you are trying to accomplish, so I'm not sure what you're missing.

Hi all, 

I'm new to eclipse Milo and opc-ua so please apologies to me, for the question if it can be seen as a stupid question.

Any help is really appreciated!!!

What I try to accomplish on the server side is an object that has some methods as child, like in the following figure:

I have tried almost everything (trying to understand the example in the milo repository), in particular in the class exampleNamespace:

https://github.com/eclipse/milo/blob/master/milo-examples/server-examples/src/main/java/org/eclipse/milo/examples/server/ExampleNamespace.java

but after 2 days spent in that, nothing has worked.

thanks
