Re: [JBoss-user] what if no beans are found by a finder ?
Hello Ionel, if finder's return type is a local interface then if the entity is not found, FinderException is thrown. If finder's return type is Collection or Set then if no entity is found an empty Collection or Set is returned (w/o exception). alex Friday, July 25, 2003, 4:53:08 PM, Ionel Gardais wrote: IG Hi, IG What happens if a finder doesn't find any beans matching its query ?

AW: [JBoss-user] what if no beans are found by a finder ?
one short question regarding the return type Collection or Set.. I thought a finder always returns a Collection or atleast the default finders. Or is there a way to make it return a Set. If yes, then is there a performance gain between the two return types..and we extensivley use iterators over these returned Colelctions. But i read some were that there is some performance difference iterating over Collection, Map, Set...can u just take few mins to eloborate..these things regards jani -Ursprungliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von Alexey Loubyansky Gesendet: Montag, 28.

Hello Janardhan, you're right, Set is not allowed as the return type for a finder.

Re: AW: [JBoss-user] what if no beans are found by a finder ?
Further clarification: I thought that if you specify DISTINCT in the EJBQL query then the system creates a Set underneath, but returns it as a Collection. This, of course, is fine as Set extends/implements Collection.
