working with splitpanes

hi i a have a jtree with checkboxes in the left pane and some components in the right pane. the components include textfield,filechooser... if i click on a checkbox in the left pane i should catch the name of the node and place it in text field on the right pane. i am able to display the node name on the console but unable to display it on the text field. i used setText() method but still not able to do so... the components on the right hand side are in a seperate class which extends JPanel and i have added the panel to the scrollpane which i added it to the splitpane. can any one please help me out............
thanks in advance

You don't seriously expect someone to write the complete working code for you, do you?

i dont need the whole code i just want any suggestions any one can give.

you may want to create a small compilable program that demonstrates your problem, a so-called SSCCE.
