I've got a class named DepenseBeneficiaire.java, which primary key is composed of attributes from the class DepenseBeneficiaireId.java. One of DepenseBeneficiaireId attributes is an enumeration, to determine which type of DepenseBeneficiaire we are dealing with.
These classes are saved in my database without any problem, but I'm having some trouble reloading them: obviously, the column dpeense_id cannot be matched back with the Java enum.

I get the following exception:
Code:
java.lang.IllegalArgumentException: Unknown name value for enum class fr.site.hibernate.classes.DepenseBeneficiaireId$NatureDepense: 16
[...]
Caused by: java.lang.IllegalArgumentException: No enum const class fr.site.hibernate.classes.DepenseBeneficiaireId$NatureDepense.16
meaning that Hibernate is trying to load the constant
NatureDepense.16 which doesn't exist, but shouldn't function
public static NatureDepense value(String identifier) be handling this matter? I ust know that Hibernate uses this function while reloading, and matches the given String with the corresponding NatureDepense.
I don't know if it's because my enumeration identifier is a String, or if I'm missing an annotation (I've tried to use @Enumerated(EnumType.STRING), but this doesn't seem to work better), or if I have to override something in my enum: any idea?
