我有一个关于JBOSS的问题。我设计了一个名为Login.jsp的jsp页面。当我运行它时，它在开始时正常工作。但是当我添加会话bean和实体时，我收到的错误如下：

有人可以帮帮我吗？
这是我的会话bean代码：
package org.jboss.as.quickstarts.greeter.domain;
import java.util.HashMap;
import java.util.Map;
import javax.ejb.Stateful;
import javax.enterprise.inject.Alternative;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.NoResultException;
import javax.persistence.PersistenceUnit;
import javax.persistence.Query;
@Stateful
public class SessionBean implements DAO {
public SessionBean() {
}
@Inject
protected EntityManagerFactory emf;
String customerName;
Integer bookID;
int quantity;
Map<Integer,Integer> shoppingCart = new HashMap<Integer,Integer>();
public void initialize(String person) throws BookException {
if (person == null) {
throw new BookException
("Null person not allowed.");
} else {
customerName = person;
}
}
public String addBook(int bookID, int quantity){
shoppingCart.put(bookID, quantity);
return "The item has been added to your cart succesfully";
}
public String removeBook(int bookID) throws BookException{
int number = shoppingCart.get(bookID);
if ( number == 0) {
throw new BookException
("The item is not in the cart.");
}
shoppingCart.remove(bookID);
return "Selected item has been removed from your cart succesfully";
}
public String updateBook(int bookID, int quantity){
shoppingCart.put(bookID, quantity);
return "The item in your cart has been updated succesfully";
}
public String checkout(Map<Integer, Integer> content){
Order order = new Order();
return "You have successfully checked out";
}
public Map<Integer, Integer> getContents(){
return shoppingCart;
}
public Customer findByPrimaryKey(int customerID){
EntityManager em = emf.createEntityManager();
Customer customer = (Customer)em.find(Customer.class, customerID);
em.close();
return customer;
}
public BookStore findByName(String name){
EntityManager em = emf.createEntityManager();
BookStore book = (BookStore)em.find(BookStore.class, name);
em.close();
return book;
}
}
这是我的persistence.xml。我忘记了什么吗？
