how to use enum with jpa as a data member of persisted entity?

Please best practice and 'how to' for using enum with jpa as a data member of persisted entity. what is the best practice? I want to persist "C", "O" from enum. (codes). If this is not the correct approach please suggest.

Enum defination is --

public enum Status{
CLOSED ("C")
OPEN ("O")
private final int value;
private Status(final int pValue){
this.value = pValue;
}

public int value(){
 return this.value;
}

expected Solution: enum defination:

public enum Status {
    CLOSED(1), NEW(2), RUNNING(3), OPEN(4), ADDED(5), SUCEESS(-1), DONE(0);
        private int code;
        private Status(int code) {
        this.code = code;
    }
        public int getCode() {
        return code;
    }
        public void setCode(int code) {
        this.code = code;
    }
        public static Status valueOf(int i){
        for (Status s : values()){
            if (s.code == i){
                return s;
            }
        }
        throw new IllegalArgumentException("No matching constant for " + i);
    }

}

Entity Definition:

@Entity
@NamedQuery(name="Process.findAll", query="select p from Process p ")
public class Process {
    
    @Id
    private long id;
    private String name;
    
    @Transient
    private transient Status status; //actual enum; not stored in db
        @Column(name="STATUS")  
    private int statusCode; // enum code gets stored in db
    
    @PrePersist
    void populateDBFields(){
        statusCode = status.getCode();
    }
    
    @PostLoad
    void populateTransientFields(){
        status = Status.valueOf(statusCode);
    }
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Status getStatus() {
        return status;
    }
    public void setStatus(Status status) {
        this.status = status;
    }
}
