Weired problem, exception should be thrown

[hubaghdadi]

Hi all.
I have a weired problem.
I have the following finder method in a local home interface:
Collection findByCityName(String city) throws FinderException;
the ejb-ql for the previous finder is:
SELECT OBJECT(T) FROM Team AS T WHERE T.city = ?1
the previous method is used by a session facade as the following :

 public Collection getTeamsByCity(String city) {
 Collection result = null;
 try {
 Collection tmp = teamHome.findByCityName(city);
 // This method will convert LocalTeam collection to a collection of TeamDTO
 result = this.convertTeamsCollection(tmp);
 } catch (FinderException e) {
 throw new EJBException("There is no such a team" ,e);
 }
 return result;
 }

now, when using this method from a client and supplied a correct value (a value that exists in a database), I got a right answer, but when supplied a value that does not exists in the database, I got nothing.
not an exception in the console, not an exception in JBoss console and not in the log file !
any ideas ??
thanks

let me ask you a qestion.
when we get a FinderException ?
I provided a value that does not exit in a database, so findByCityName( ) should throw an excpetion, but it don't.
in which situations we get FinderException ??
thanks.

You are seeing the correct behaviour, having no data returned from a query is a valid response.

If the return type of your finder methods were to return the remote / local interface instead I think that you would then see the Exception.
