Hi Flavio,

It looks like your classpath isn't as it should be. Instead of a WOSession you 
get a org.apache.axis.session.Session. And the d2wmodel files don't seem to get 
referenced correctly either. You could open one of them, e.g. 
/Users/fdonadio/Projects/WonderSource/Frameworks/D2W/ERModernLook/build/ERModernLook.framework/Resources/d2w.d2wmodel
 in RuleModeler and see whether it can be opened at all and whether the 
contents look OK.

Fabian
