Subject Re: Geronimo - EJB3.1 - Eclipse

AFAIK geronimo 2.2 supports ejb 3.0, ejb 3.1 support is in progress  
for geronimo 3.0.  I know there are some features already implemented,  
and I thought singletons were among the implemented features.  However  
you shouldn't expect full ejb 3.1 compliance from geronimo 2.2.
