How do you debug a bean?

Hi,

How does one debug a bean? I have one bean that calls another bean and
calls another but I cannot see what is going on :-(

Does anyone out there have an example with out.println or something
like that so you can see what is going on?

I have stopped using the Netbeans and am using this Exadel now. If
anyone knows how to use the debugger out of that application, would be
appreciated.

TIA
