How to createNode in java backed?

[dark_rider]

I am trying to create a new node but not success. How could I perform it? Basicly I want to copy a node and change its content.

final String NAMESPACE = "http://www.alfresco.org/model/demoscripts/1.0";
final QName PROP_QNAME_MY_PROPERTY = QName.createQName("custom.model", "myProperty");
…
…
NodeRef newNodeRef = getNodeService().createNode(parentRef, ContentModel.ASSOC_CONTAINS, QName.createQName(NAMESPACE, newNodeName), PROP_QNAME_MY_PROPERTY).getChildRef();
‍‍‍‍‍‍

I get this exception
java.lang.IllegalArgumentException: Class {custom.model}myProperty has not been defined in the data dictionary

How can I create node simply? Could you please help me?

Here's one I prepared earlier ….

          ChildAssociationRef child = nodeService.createNode(A4NodeRef, ContentModel.ASSOC_CONTAINS, QName.createQName("A7"), ContentModel.TYPE_CONTENT);

I think your problem is with the last argument.    Have you really defined a type with the name myProperty?  :?

The error message is saying that alfresco does not know what type a  {custom.model}myProperty is.

Exactly you are right, the last argument was wrong, I have changed it with ContentModel.TYPE_CONTENT and it works.
There is no example about that so I could not know how it works.
Thanks you so much…
