I need to get the parent node when highlighting a child node:

node 1
---node1.1
---node1.2
---node1.3
---node1.4
node 2
---node2.1
---node2.2

So if I highlight node 2.2....
I can get that string by :

String node = jt.getSelectionPath().getLastPathComponent().toString();

But the question is... how do I get it's parent node as a String.... highlighting the child?

String parentNode = ?

String parent = jt.getSelectionPath().getPathComponent(0).toString();

always gives me the same String.... parent node 1.... its suppose to give me the parent node for any child node..... so for node 2.2 ... i want node 2..... node 4.8 ... i want node 4.

------------------------------

System.out.println(jt.getSelectionPath().getLastPathComponent());

gives me the highlighted node.
