Java Reflection Setter

I am trying to set the values of class member variable by using java reflection but during invocation of method it will stop and it doesn't throw any exception or error . It's irritating I am stuck here plz help me.................... Here is my code public class SMapper {

public void SetMapforvalues(Hashtable obj) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException, NoSuchMethodException {

    Field[] fields = this.getClass().getDeclaredFields();

    for (Field field : fields) {

        String fieldName = field.getName();
        Object value = obj.get(fieldName);

        if (value != null) {

            Class<?> type = field.getClass();

            if (type.equals(Integer.class)) {
                Integer data = (Integer)value;
                field.set(this, data);       

            } else if (type.equals(String.class)) {
                String data = (String)value;                    
                field.set(this, data);
            } else if (type.equals(Double.class)) {
                Double data = (Double) value;
                field.set(this, data);       
            } else {

                Method method = type.getMethod("SetMapforvalues");
                Object methodreturn = method.invoke(value, obj);                  

            }
        }
