thanks again for your help but that doesn't seam to be the problem.

if I get the list before trying to register the nodes and after I registered
I get the same list.

I'm using this:
NodeTypeIterator nodeTypeIt =
session.getWorkspace().getNodeTypeManager().getAllNodeTypes();

and not even one of the node types I tried aren't there.

I also tried to get the node type by name as it's advised in the previous
mail but I get an exception:
StorageRepositoryException: javax.jcr.nodetype.NoSuchNodeTypeException:
ctn:nosamenamesiblings

well, at least I get an exception :)
when I try to register I get nothing!


any ideas before I start hacking into the CndImporter code to put some
logging?

thanks in advance.


best regards,

bruno coelho
