Apache commons beanutils how to set property value?

Question

In java, commons beanutils, try setting the 'address' and 'creditCardList' property for the object, but this gave me an error:

java.lang.NoSuchMethodException: Property 'address' has no setter method in class 'class com.dao.Student' 

but I have this method. The code is here:

 public class Main { public static void main(String[] args) { Object student = new Student("John"); Object address = new Address("NJ"); try { PropertyUtils.setProperty(student, "address", address); //---------- List list = new ArrayList(); Object creditCard = new CreditCard(); list.add(creditCard); PropertyUtils.setProperty(student, "creditCardList", list); } catch (Exception e) { e.printStackTrace(); } } } class Student { private String name; private Address address; private List<CreditCard> creditCardList; public Student(String name) { super(); this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Address getAddress() { return address; } public void setAddress(Address address) { this.address = address; } public List<CreditCard> getCreditCardList() { return creditCardList; } public void setCreditCardList(List<CreditCard> creditCardList) { this.creditCardList = creditCardList; } } class Address { private String name; public Address(String name) { super(); this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } } class CreditCard{ private String cardName; public String getCardName() { return cardName; } public void setCardName(String cardName) { this.cardName = cardName; } } 

Answer 1

I moved Student to my own file and made it publicly available, which worked great :)

Answer 2

Your Student class should be an open class, try making it public and repeating your code.
