    }
    return userDetails;
}

Während der Fehlersuche im Code wird die Ausnahme in der 2. geworfen while-Schleife, wo ResultSet rs2 für die nächste () und NavLinkDto navlink Objekt geprüft wird bevölkert von navlink.setLinkText (rs2.getString (1)). Die While-Schleife ausgeführt wird erstmals als erwartet und auffüllt NavLinkDto Objekt Danach überprüft er wieder für den nächsten () und erzeugt die Ausnahme

Ausnahme in Ziel-VM: Operation nicht erlaubt nach ResultSet geschlossen <

Ich verstehe nicht, warum die ResultSet innerhalb der while-Schleife ist geschlossen zu werden. Gibt es irgendein Problem mit der Kodierungsstruktur?

Während der Fehlersuche im Code wird die Ausnahme in der 2. geworfen while-Schleife, wo ResultSet rs2 für die nächste () und NavLinkDto navlink Objekt geprüft wird bevölkert von navlink.setLinkText (rs2.getString (1)). Die While-Schleife ausgeführt wird erstmals als erwartet und auffüllt NavLinkDto Objekt Danach überprüft er wieder für den nächsten () und erzeugt die Ausnahme

Ausnahme in Ziel-VM: Operation nicht erlaubt nach ResultSet geschlossen <

Ich verstehe nicht, warum die ResultSet innerhalb der while-Schleife ist geschlossen zu werden. Gibt es irgendein Problem mit der Kodierungsstruktur?
