[kepler-dev] debuging in actor development

[Norbert Podhorszki]

Hi Bertram,

I use the strongly suggested way: log4j logging. Much better than
println.

A built-in source line debugger during workflow execution in Kepler would 
be nice though ;-) but I think Eclipse users are able to do that as 
well.
