public interface ShoppingCart extends javax.ejb.EJBObject{
boolean addItem(int itemNumber) throws
java.rmi.RemoteException;
boolean purchase() throws Java.rmi.RemoteException;
}
public class ShoppingCartEJB implements SessionBean{
public boolean addItem(int itemNumber){
// the code for adding items to the cart
// may include JDBC code.
}
public boolean purchase(){
//the code for purchases
}
public ejbCreate(String accountName, String account){
// object initialization code
}
}
public interface CartHome extends Javax.ejb.EJBHome{
Cart create(String customerName , String account)
throws RemoteException, BadAccountException;
}
Context initialContext = new InitialContext();
CartHome cartHome = (CartHome) initialContext.lookup
("application/mall/shopping-carts");
ShoppingCart cart = cartHome.create("Emma","0507");
Cart.addItem(100);
Cart.addItem(251);
Cat.purchase();
在上述代碼中, create()方法創建了一個新的session Bean, 變量cart 包括了一個對遠程EJB Object的引用, EJB Object允許你調用它的方法additem()和purchase()。cartHome中的create()方法將調用對應的Bean中的ejbCreate()方法。
