I've been following along with an example using EJB3/JBOSS from the book
Beginning Java EE 5 Platform and don't know why JBoss is complaining about an annotated private instance of an Entity Manager.
I was wondering if anyone can let me know where I am going wrong.
Here is the code:
| package beans;
|
| import javax.persistence.Entity;
| import java.io.Serializable;
| import javax.persistence.Id;
|
| @Entity
| public class Stock implements Serializable {
| // The persistent fields
| private String tickerSymbol;
| private String name;
|
| // Constructors
| public Stock() {}
| public Stock(String tickerSymbol, String name) {
| this.tickerSymbol = tickerSymbol;
| this.name = name;
| }
|
| // The access methods for persistent fields
| // tickerSymbol is the id
| @Id
| public String getTickerSymbol() {
| return tickerSymbol;
| }
|
| public void setTickerSymbol(String tickerSymbol) {
| this.tickerSymbol = tickerSymbol;
| }
|
| public String getName() {
| return name;
| }
|
| public void setName(String name) {
| this.name = name;
| }
| }
|
| package beans;
|
| import javax.ejb.Remote;
|
| @Remote
| public interface StockList {
| // The public business methods on the StockList bean
| public String getStock(String ticker);
| public void addStock(String ticker, String name);
| public void updateStock(String ticker, String name);
| public void deleteStock(String ticker);
| }
|
| package beans;
|
| import beans.Stock;
| import javax.persistence.PersistenceContext;
| import javax.ejb.Stateless;
| import javax.persistence.EntityManager;
|
| @Stateless
| public class StockListBean implements StockList {
|
| // The reference to the entity manager
| @PersistenceContext
| private EntityManager _manager;
|
| // The public business methods. These must be coded in the
| // interface also
|
| public String getStock(String ticker) {
| Stock stock = _manager.find(Stock.class, ticker);
| return stock.getName();
| }
|
| public void addStock(String ticker, String name) {
| _manager.persist(new Stock(ticker, name));
| }
|
| public void updateStock(String ticker, String name) {
| Stock stock = _manager.find(Stock.class, ticker);
| stock.setName(name);
| }
|
| public void deleteStock(String ticker) {
| Stock stock = _manager.find(Stock.class, ticker);
| _manager.remove(stock);
| }
| }
|
I've deployed a jar called StockListApp.ejb3 with the classes compiled from this code and come up against the following error
