i have jTree (for example):

-paper
    -coated
    -glossy
        -hummermill
        -quatro
        -springhill
    -matte

when i select springhill i get index of 5, but i dont want to count from the root(paper) (that includes parents and other nodes outside the glossy), i want to start counting from hummermill so i try to get index of 2.

i used tree.getLeadSelectionRow() and get int value of 5; also i use node.getIndex(node) but here i dont get anything normal (0,3,-1). I try all variations of all metods there is for node and tree and find nothing helpfull. plese help!

You have to find the index of node from its parent 

  DefaultMutableTreeNode node=(DefaultMutableTreeNode) jTree1.getSelectionPath().getLastPathComponent();

  System.out.println(node.getParent().getIndex(node));
