Java Tutorial/EJB3/Injection

EJB Field Injection

File: AnotherEJBLocal.java

import javax.ejb.Local;
@Local
public interface AnotherEJBLocal {
  public void doAnother();

}

Inject EJB With EJB Annotation

File: AnotherEJBLocal.java

import javax.ejb.Local;
@Local
public interface AnotherEJBLocal {
  public void doAnother();

}

Inject Session Context

File: Employee.java

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.PostRemove;
@Entity
public class Employee implements java.io.Serializable {
  private int id;
  private String firstName;
  private String lastName;
  @Id
  @GeneratedValue
  public int getId() {
    return id;
  }

  @PostRemove
  public void postRemove()
  {
     System.out.println("@PostRemove");
  }
  public void setId(int id) {
    this.id = id;
  }
  public String getFirstName() {
    return firstName;
  }
  public void setFirstName(String first) {
    this.firstName = first;
  }
  public String getLastName() {
    return lastName;
  }
  public void setLastName(String last) {
    this.lastName = last;
  }
}

Setter Injection

File: AnotherEJBLocal.java

import javax.ejb.Local;
@Local
public interface AnotherEJBLocal {
  public void doAnother();

}
