I want to add a type definition node from client side by using the following code:
NodeId typeDefinition=null;
NodeClass nodeClass=NodeClass.ObjectType;
NodeId parentNode=Identifiers.RootFolder; // or i also check with parentNode = BaseObjectType which is defined in root->types->ObjectTypes->BaseObjectType
NodeId referenceTypeId=Identifiers.HasSubType;
NodeAttributes nodeAttributes=null;
ObjectAttributes objectAttributes=new ObjectAttributes();
objectAttributes.setDescription(LocalizedText.english(“I am a Object Node”));
objectAttributes.setSpecifiedAttributes(UnsignedInteger.ONE);
objectAttributes.setUserWriteMask(UnsignedInteger.ONE);
objectAttributes.setWriteMask(UnsignedInteger.ONE);
nodeAttributes= objectAttributes;
NodeId newNodeId = new NodeId(2,name);
QualifiedName browseName=new QualifiedName(2,”name”);
nodeAttributes.setDisplayName(new LocalizedText(“name”));
NodeId Id = client.getAddressSpace().addNode( parentNode,
referenceTypeId,
newNodeId,
browseName,
NodeClass.ObjectType,
nodeAttributes,
typeDefinition);

i am creating a object type definition node…. for adding any object or variable node i specify its typedefinition node that is already present in my address space ……. but if i want to add a node that is itself a TYPEDEFINITION node , so i send the typeDefinition parameter as null which gives error on server side
