Re: [xmlblaster] xmlBlaster client as OSGi bundle (eclipse plugin)

[Michele Laghi <laghi at swissinfo.org>]

Hi Kai,
there are some requirements about classloader when using xmlBlaster
embedded:

http://www.xmlblaster.org/xmlBlaster/doc/requirements/util.classloader.ClassLoaderFactory.html
and
http://www.xmlblaster.org/xmlBlaster/doc/requirements/util.classloader.XmlBlasterClassLoader.html

particularly have you tried to set

classloader.xmlBlaster=true in the property file ?

I am not familiar with OSGI so could you tell me which implementation of
the Class loader is used ?

Regards
Michele
