Drag N Drop in JTables

Question

Hi !
I have two scenarios
1) I need to be able to drag and drop rows from a given table to the other table.
2) I should be able to drag and drop rows with in the same table( This case is same as rearranging the rows with in the table with the help of MouseDragged Event).
Is this possible using Drag N Drop in swing? Greatly appreciate solutions and online resources which can help me write my custom TransferHandler for the above purposes

Ok, here's the promised source code
When the Class is initialized you need to create a couple of objects
          DragSource dragSource = DragSource.getDefaultDragSource() ;
          dragSource.createDefaultDragGestureRecognizer(this, DnDConstants.ACTION_COPY_OR_MOVE, this) ;And you will need the following method
     public void dragGestureRecognized(DragGestureEvent e) {
          String v = (String) getSelectedValue() ;
          e.startDrag(DragSource.DefaultCopyDrop, new StringSelection(v), this) ;
     }or a variation on it. You will of course need the imports and such to support these, but most of it is in the java.awt.dnd package.
Then in your target you'll need a method to catch the drop ...
     public void drop(DropTargetDropEvent e){
          try{
               DataFlavor stringFlavor = DataFlavor.stringFlavor ;
               Transferable tr = e.getTransferable() ;
               if(e.isDataFlavorSupported(stringFlavor)){
                    String name = (String) tr.getTransferData(stringFlavor) ;
                    e.acceptDrop(DnDConstants.ACTION_COPY_OR_MOVE) ;
                    Point p = e.getLocation() ;
                    int x = Integer.parseInt(String.valueOf(Math.round(p.getX()))) ;
                    int y = Integer.parseInt(String.valueOf(Math.round(p.getY()))) ;
                    int i = lastScenarioIndex++ ;
                    addDrawingObject(
                         new ScenarioDrawingObject("SCENARIO_" + i, "SCENARIO_" + i, y, x,
                         new SequenceMemberDrawingObject(name, name, 20, 20))) ;
                    resizeContainer() ;
          catch(IOException ioe){
               ioe.printStackTrace() ;
          catch(UnsupportedFlavorException ufe){
               ufe.printStackTrace() ;
     }There's a little more to it, but that's the crux of it.
Cheers.
