[kepler-dev] Running Kepler from Eclipse...No actors on right pane

[David Welker]

Hi Christopher,

I agree with you about the naming of the startup class. It is a little 
bit tricky, because Kepler has evolved such that there are several 
startup classes layered on top of each other. I think we need to take a 
look at this at some point and rationalize it. It actually is nice to 
have different startup classes in the following sense. Different modules 
will need to perform different startup tasks. For example, the startup 
class org.kepler.loader.Kepler (which is called by 
org.kepler.core.loader.Loader) is different when working with 
kepler-trunk versus kepler-1.0. So, having multiple startup classes does 
give us some flexibility we wouldn't have otherwise. Nonetheless, it 
should be simplified and also these classes need to be named in a more 
careful manner.
