[news.eclipse.tools.emf] Re: emf java error

[Ed Merks <Ed.Merks@xxxxxxxxx>]

Upkar,

My guess would be that a different version of EClass is being loaded 
than the one against which the code was compiled.  WAS embeds a version 
of EMF for internal use and that's the one that will be used by default 
unless you do some class loader last thing (I forget the details) and 
supply the actual version you want...  Best to check with your friendly 
helpful WAS support forums for details.
