i would like ADDING ejb3 beans.  but i don't want to to remove the EJB2 beans for backward compatibility reasons.  the majority of containers will be ejb2 for a while.  so we need ejb2 beans.

i have not focussed on ejb3 beans for now because that would imply that we have to factor out the common code.  so the ejb3 simplifications would be countertackled by factoring out the common code between the ejb2 and ejb3 beans.

so i'm not sure if that is worth while.

the thing i don't know is the actual configuration in the deployment descriptor.  feel free to add this configuration property in the deployment descriptor if you know which one it is.

please define non-system exception.  afaik this means non-RuntimeExceptions, right ?
