Re: [xmlblaster] PluginClassLoader

[Michele <laghi at swissinfo.org>]

Hi Nelson,

The simplest (and xmlBlaster stylish correct) way of loading plugins is 
via the run level manager.

Then again, if you want to dynamically instantiate objects you could use 
the plugin loaded by the run level manager to instantiate these objects 
dynamically. For example the plugin could subscribe on certain messages 
and either do delegate subscribes or load other objects (other clients) 
doing that.

Michele
