[kepler-dev] debuging in actor development

[Dan Higgins]

Hi All,
    Actually, the 'Listen to Actor' menu has been removed from Kepler. 
(I am not at all sure why!)

    You can always debug with simple 'System.out.println(...)' 
statements in the actor code. Results appear in the command prompt 
window used to launch Kepler. Kepler uses log4j in many of its actors. 
Check the Kepler wiki and search for 'log4j' for details.
