Get the position or move the mouse to the selection

[Tarakesh]

I have a situation where the desktop is designed in java swings. The nodes JTree is not allowing me to do checkbox selection using "spacebar". I am able to navigate through the nodes using up, down arrow and a tab. When I reach to the desire node selection, mouse left click is not working due a flaw a JTree core. However since it is selected, if mouse cursor auto moved to the position of the selection and send a "click"  then it should be solved. Any ideas much appreciated. 
the problem with having fixed coordinates are the main windows is divided to 2panels where right panel containing this JTree can be expanded or shrink-ed.
