This Java tip demonstrates a method of listing names of various properties of a bean. The bean properties are entities that participate to the mapping process. They are usually the fields of the data bean. However, this isn't a requirement since the get & set methods of the data bean define the bean properties. The mapping utilities use the JavaBeans' introspection API to get the names and the types of the properties of a data bean.

 try {
    
        BeanInfo bi = Introspector.getBeanInfo(MyBean.class);
        PropertyDescriptor[] pds = bi.getPropertyDescriptors();
        
        for (int i=0; i<pds.length; i++) {
            // Get property name
            String propName = pds[i].getName();
        }
        
        // class, prop1, prop2, PROP3
        
    } catch (java.beans.IntrospectionException e) {
    }
    
    public class MyBean {
        
        // Property prop1        
        public String getProp1() {
            return null;
        }
        
        public void setProp1(String s) {
        }
    
        // Property prop2
        public int getProp2() {
            return 0;
        }
        
        public void setProp2(int i) {
        }
    
        // Property PROP
        public byte[] getPROP3() {
            return null;
        }
        
        public void setPROP3(byte[] bytes) {
        }
    }
