..if the user clicks on the particular node of the tree(left pane) then corresponding table should be displayed on (right pane)
This should not be difficult enough to build. 1) Create a custom object. 2) Wrap it inside a DefaultMutableTreeNode and build a JTree from it. 3) Figure out which node the user has selected 4) Extract the custom object from the selected node 5) Pass the object to the table model and ask it to update the table.
