debugging with jdb

[Sadikin, Heny]

Hi,
I'm trying to use ddd version 3.3.1 with JDB as my inferior debugger. I'm
having problem with stopping at the specified breakpoints. Here's the steps
I did:
1. Start ddd --jdb -classpath....
2. File->Open Class
3. Set a breakpoint 
4. Run

The Debugger console shows this:
Stopping due to deferred breakpoint errors.
No frames on the current call stack

Requested stack frame is no longer active: 0

My program doesn't really stop at the breakpoint. Any help would be
appreciated. If there are more manual or articles about using ddd with JDB,
that will be great too.

Thanks,
Heny Sadikin
