How to start Enhanced Debugger?

Hi there,

I checkedout 1 of the instruction as to start the spark client (2.5.8b) with the debug mode option. I also tried to specify the debugger (to given EnhancedDebugger) but it don’t show up the enhanced debugger window. It only starts the tool.

Above is the document where they mention as how to do that debuging. Can any 1 please help me out?

Thanx in advance.
