Re: [xmlblaster] Logging (Factory)

[Peter Antman <pra at mint.se>]

Seems as if its verry hard to do this because of circular dependancies:

To set up a logg plugin manager to initialize logging entails creating
one in a Global constructor (so that it is available in initLog).
However the PluginManagerBase uses the Global to set up loging - and
that will mean that PluginManager will start trying to use Global before
it has actually been created:

 (java.lang.StackOverflowError)


Any ideas about this, or should I just give up ;-(
