Typically, remotely accessible objects should be coarse-grained.

If a client accesses an enterprise bean locally such access must be mediated by the EJB container.

A given enterprise bean's transaction information is immutable because it is deployed across various containers.

If a container provides services NOT required by the EJB specification, then that container is NOT considered to be an EJB container.

An enterprise bean's transaction Information can be accessed by external tools only if the information is contained in an XML deployment descriptor.
