Getting error with Bean Object property not writtable at sqlmap config initial load

Title: Getting error with Bean Object property not writtable at sqlmap config initial load

I'm get this error below. What's the problem.

Cause: com.ibatis.common.beans.ProbeException: There is no WRITEABLE property named 'netPrefixID2' in class 'Network'

Network.java:

import java.io.*;

public class Network implements Serializable {
        private int netPrefixID2;

       
        public void setNetPrefixID(int netPrefixID2)
        {
                this.netPrefixID2 = netPrefixID2;
        }

        public int getNetPrefixID()
        {
                return netPrefixID2;
        }

}

network.xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
