Hi all,

J have a common question about the J2EE-Specification, perhaps somebody can give me a short answer:

The J2EE-Specification describes the features of an J2EE application server, ob what the server has to do.
Where are the major differences between J2EE application server or better what can they do to be better than the other vendors.
Where are the vendors free in implementing a service?

thanks
