adding nodes programmatically: Exc

[Christian Eugster <ch...@gmx.net>]

Hi,

I checked the internet resources (google, sling website etc) as good as 
I can, but have not found a answer that I could follew to the following 
problem:

I want to add Nodes to a sling repository by a service component. The 
component references SlingRepository. After getting a Session from 
loginAdministrative (thanks to Bertrand Delacretaz who showed me that 
way) I check if the node in question is already added 
(parent.hasNode(name). If yes, I get it (getNode(name) else I add a new 
node to the parent node with addNode(name).

Because it is content I want to add the "sling:resourceType" property:

documentNode.setProperty("sling:resourceType", "thun/documents");

but get a ConstraintViolationException saying

no matching property definition found for 
{http://sling.apache.org/jcr/sling/1.0}resourceType

What am I doing wrong?

Thank you

Christian

Or use more permissive node types like nt:unstructured and
sling:Folder for the parent nodes.

The child node created by your addNode(name) call has a node type that does
not declare "sling:resourceType" as an allowed property for the node.

So you would either need to use the addNode variant (see [1]) that
specifies a primary nodetype for the new node that does allow that
property, or add a mixin type that adds the property declaration.

For example:

//use a some primary node type where 'sling:resourceType' is already
allowed
node.addNode(name, "nt:unstructured");

or:

//create a child using the default primary node type
Node child = node.addNode(name);
//add mixin type (see [2]) to make sure the 'sling:resourceType' property
is allowed
child.addMixin("sling:Resource");
