The following is one of the bullet points mentioned of pg 420 of HF EJB book. " A SELECT can return either an <abstract-schema-type> (which really means the bean's local component interface type), or a single-value field." I did not understand why is it only a local component interface type and not a remote component interface type.
Yep, it looks like this should just be "component interface" and not "local component interface... it even says so back on page 408. Maybe they got confused with all the CMR stuff on that page, since CMR requires everything to be local. You should submit errata for this over on the HeadFirst EJB Errata Page on O'Reilly's website.
