Your import statement (in your teste code) must be wrong; otherwise, java
would pick it up.
To determine if its a CLASSPATH issue, try this:
javax.swing.tree.DefaultTreeModel model = new
javax.swing.tree.DefaultTreeModel(root);
That'll tell you if you left out the import, got the import wrong, or your
CLASSPATH is screwed up somehow. (Honestly, though, if the CLASSPATH were
screwed, you'd be getting a lot more errors than this one--I'm betting my
money on the import statement.)
