Java ME: transform basic JDK 1.5 "enum" object into Java ME CLDC-1.1/IMP-NG (JDK 1.4)

Question

I'm translating a Java (JDK 1.5) "enum" into Java ME (JDK 1.4).

Many people have suggested retroweaver to parse JDK 1.5 libraries to JDK 1.4 but I've got a lot of problems using it and I really want to get full control of my project due the HW limitations.

What's the best way to translate it or find an equivalent?

/** 
 Authentication enumerates the authentication levels.
*/
public enum Authentication
{
    /** 
     No authentication is used.
    */
    NONE,
    /** 
     Low authentication is used.
    */
    LOW,
    /** 
     High authentication is used.
    */
    HIGH,
    /*
     * High authentication is used. Password is hashed with MD5.
     */
    HIGH_MD5,
    /*
     * High authentication is used. Password is hashed with SHA1.
     */
    HIGH_SHA1,
    /*
     * High authentication is used. Password is hashed with GMAC.
     */
    HIGH_GMAC;

    /*
     * Get integer value for enum.
     */
    public int getValue()
    {
        return this.ordinal();
    }

    /*
     * Convert integer for enum value.
     */
    public static Authentication forValue(int value)
    {
        return values()[value];
    }
}

This 1997 article shows how to create enumerated constands in Java.

The idea is to have a final class with a private constructor and public constants. The example used is:

public final class Color {

  private String id;
  public final int ord;
  private static int upperBound = 0;

  private Color(String anID) {
    this.id = anID;
    this.ord = upperBound++;
  }

  public String toString() {return this.id; }
  public static int size() { return upperBound; }

  public static final Color RED = new Color("Red");
  public static final Color GREEN = new Color("Green");
  public static final Color BLUE = new Color("Blue");
}
