**aitBaamran** · 25/07/2012, 13h34

Je suis entrain de faire le mapping d'une class user est userDto dans une la premiere fois ou les deux class contient les mêmes attributs tout marche bien une fois que j'ai modifier User(la class)--->username(attributs)
UserDton----> login

J'ai l'erreur suivante :

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.NotReadablePropertyException: Invalid property 'username' of bean class [spring.users.UserDTO]: Bean property 'username' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
