Persisting enums

I've been all over the place, but still seem to be lost on the best way to persist enum values that have string representations.

Code:

public enum Codes
{
    LATE("L"),
    ON_TIME("OT"),
    EARLY("E"), 
    Unknown("U") 
                
    String codeValue; 

     Codes( String cv) 
          { codeValue= cv; } 

     public String valueOf() { return codeValue; } // or whatever here
} 

Code:

@Entity
public class ...
{
  private Codes code;
   ...

  @Column(name="code")
  @Enumerated(EnumType.STRING) // not what I'm after
  public getCode()
  {
      return code;
   }
}

Using that as the enum, I want to be able to persist the values of the enum instead - Enumerated(EnumType.STRING) simply puts the enum itself as a string, not the assigned value of that enum (LATE vs. L)....

Maybe I'm asking to much of it ;) I have looked around so much and am still pretty clueless about this scenario. I have seen some very complicated examples of custom enum type classes, etc, but nothing that is any clearer than, well, mud![/code]

Save it as a user type.For that you will have a class that implements UserType. In the methods that you will implement; get the approprate value of your enum and save and get from DB.
Have your entity property annotated as @Type(type="youEnumType")

Is there some kind of decent example of this?
