Spring Batch FlatFileItemWriter

Question

salve sto cercando di leggere u oggetto e scivere un oggetto ma ricevo un errore : Invalid property 'KDE22' of bean class [com.Bnl.Wl.Batch2.Model.EmployeeOut]: Bean property 'KDE22' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
