JTree addSelectionPath and ClassCastExceptions

Question

Hi.
I'm trying to build a tree view from a list of strings that represent relative path names (ie: Icons\a\image.dds)
I have tokenized the path name based on the file separator and placed it into a String array which is used to create a new TreePath object, but when I try to add the tree path to the tree using tree.addSelectionPath(TreePath) it throws a ClassCastException: java.lang.String.
Is this something I am doing wrong, or is this a problem with java? I have extensively searched the forum and have not found anything that relates to this.
Thanks in advance.

Same question on "model" and "view":
JTable build on top of TableModel, I think the implenmentation of JTable constructor like this: invoke the methods of TableModel and get the rowCount and columnCount number, then according rowCount and columnCount number and "getValueAt()" method build a doulble "for" loop to create vector of vector, then according the vector of vector to build a table and draw the table, are these ideas correct?
The question is every time when we modify the TableModel, we explicitly call "fireTableDataChanged()" method, this method will notify all of the listeners, where are these listeners? did these listeners recall JTable constructor to rebuild the table and draw? if yes, how does this happen? if not, where do we recall double "for" loop? it seems the simple and easys way to recall JTable constructor, but if we rebuild JTable object, how can we notify the JPanel to redraw? it seems lots of mystry on "model" and "view" for me.
The big question is no body answer my questions, it is because my questions so simple, so easy or so stupid, I am new in Java, that's why I have these questions, I need Java professionals to help me!
Thanks for all your help!
