    copied!<p>I have a small sample application in which I want to implement hibernate cascading effect in which I have a person model and a creditcard model. One person can have more then one credit card.</p> <p>Here is the person model:</p> <pre><code>import java.io.Serializable; import java.util.HashSet; import java.util.List; import java.util.Set; import javax.persistence.Column; import javax.persistence.Embedded; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.OneToMany; import javax.persistence.Table; /** * Represents a person entity * * @author * */ @Entity @Table(name = "PERSON") public class Person implements Serializable { private static final long serialVersionUID = -5527566248002296042L; public Person() { } public Person(String furstBame) { this.firstName = furstBame; } @Id @Column(name = "ID") @GeneratedValue(strategy=GenerationType.AUTO) private Integer id; @Column(name = "FIRST_NAME") private String firstName; @Column(name = "LAST_NAME") private String lastName; @Column(name = "MONEY") private Double money; @OneToMany (mappedBy="person") private List&lt;CreditCard&gt; creditCards; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public Double getMoney() { return money; } public void setMoney(Double money) { this.money = money; } public List&lt;CreditCard&gt; getCreditCards() { return creditCards; } public void setCreditCards(List&lt;CreditCard&gt; creditCards) { this.creditCards = creditCards; } } </code></pre> <p>And here's the credit card model:</p> <pre><code>import java.io.Serializable; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.ManyToOne; import javax.persistence.Table; /** * Represents a credit card entity * * */ @Entity @Table(name = "CREDIT_CARD") public class CreditCard implements Serializable { private static final long serialVersionUID = 5924361831551833717L; public CreditCard() { System.out.println("CreditCard"); } @Id @Column(name = "ID") @GeneratedValue private Integer id; @Column(name = "TYPE") private String type; @Column(name = "NUMBER") private String number; @ManyToOne @JoinColumn (name="person_ID") private Person person; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getType() { return type; } public void setType(String type) { this.type = type; } public String getNumber() { return number; } public void setNumber(String number) { this.number = number; } public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } } </code></pre> <p>Please edit the code and anybody please explain the actual syntax to add cascade in these situation. I am using annotations and not the XML thing.</p>
