Select JTree root node

Hi all!
Maybe this is very simple, but I am struggling to get the root node of a
JTree if nothing is selected in the tree. On my JTree object, I invoke could
invoke:

((DefaultTreeModel)bookmarkTree.getSelectionModel()).getRoot();

This delivers the user object, but I need the root node as

DefaultMutableTreeNode, not as user object. How can I achieve this?

Thanks

Ulrich

jtree.getModel().getRoot();

Thomas, this returns (as stated in my original post) the user object,
but I need the DefaultMutableTreeNode object! So your solution is
exactly my problem :-(

Thanks&regards

Repeating that statement doesn't make it true.
