Sub-classing AbstractHandler

["Yang, Gang CTR USA" <ga...@us.army.mil>]

Hi,

I have a question about the AbstractHandler.init() method. If I
sub-class AbstractHandler and override the init() method, am I required
to call the super.init(..)? I took a quick look at the souce code for
AbstractHandler.init(), the only thing it does is to set the
HandlerDescription field. How is the HandlerDescription used by Axis2
engine? Would it create problem if HandlerDescription field remains the
default one?

Ultimately I'm looking to understand the protocol behind the Handler
interface between Axis2 engine and the Handler implementor and I did not
seem to be able to find it.

Thanks,
Gang
