How come this sql exected from Java gives a empty resultset?

Hello guys!

I got a small Java-app thats works like below.

ResultSet resultSet = statement.executeQuery( "select * from BETALD_ARTIKEL where FK_BETALNINGID = 1
");
           
//Loop through result
ResultSetMetaData resultSetMetaData = resultSet.getMetaData();
int columnCount = resultSetMetaData.getColumnCount();
while (resultSet.next())

... how ever I do not find any rows.

My test table looks like this with the data:

create table betald_artikel (
id int not null,
fk_betalningid int not null,
fk_ansokanid int,
CONSTRAINT betald_artikel_betalning FOREIGN KEY (fk_betalningid) REFERENCES betalning (id),
CONSTRAINT betald_artikel_ansokan FOREIGN KEY (fk_ansokanid) REFERENCES ansokan (id),
typ char(16),
status char(16)
);

insert into betald_artikel values(1, 1, 1, 'typaaaaaaaaaaaaa', 'EJ_HANDLAGD');
insert into betald_artikel (id, fk_betalningid, typ, status) values(2, 1, 'typbbbbbbbbbbbbb', 'HANDLAGD');


...and from sqlplus it the query works fine!

Do you see any misstake I do?

Best regards
