java.lang.RuntimeException：GWT中的延迟绑定错误

我正在关注here的教程。我试图从我的模块进行RPC调用。但我得到这个错误。java.lang.RuntimeException：GWT中的延迟绑定错误

java.lang.RuntimeException: Deferred binding failed for 'myPackageName.client.StockPriceService' (did you forget to inherit a required module?)

我StockPriceService类是：

@RemoteServiceRelativePath("stockPrices") 
public interface StockPriceService extends RemoteService{ 

    StockPrice[] getPrices(String[] symbols) throws DelistedException; 
}

StockPriceServiceAsync类是：

public interface StockPriceServiceAsync { 

    void getPrices(String[] symbols, AsyncCallback<StockPrice[]> callback); 
}

我StockPrice类是：

public class StockPrice implements Serializable{ 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 
    private String symbol; 
    private double price; 
    private double change; 

    public String getSymbol() { 
     return symbol; 
    } 

    public void setSymbol(String symbol) { 
     this.symbol = symbol; 
    } 

    public double getPrice() { 
     return price; 
    } 

    public void setPrice(double price) { 
     this.price = price; 
    } 

    public double getChange() { 
     return change; 
    } 

    public void setChange(double change) { 
     this.change = change; 
    } 

    public double getChangePercent() { 
     return 100.0 * this.change/this.price; 
    } 

    public StockPrice(String symbol, double price, double change) { 
     super(); 
     this.symbol = symbol; 
     this.price = price; 
     this.change = change; 
    } 
}

我总是得到错误，当以下里ne在我的EntryPoint中执行类

private StockPriceServiceAsync stockPriceSvc = GWT.create(StockPriceService.class);

任何形式的帮助表示赞赏。

请发布完整的堆栈跟踪，将有根本原因的详细信息 – nayakam 2015-02-10 05:15:02

您可以发布您的StockPrice类 – nayakam 2015-02-10 05:17:23

@Thillakan，已更新。一探究竟。 – 2015-02-10 05:20:59

StockPrice必须具有零参数构造函数或根本没有构造函数用于默认启动。请检查堆栈跟踪并确认。

yap。添加一个零参数构造函数解决了这个问题。凉。 – 2015-02-10 05:51:08
