引起︰javax.naming.NameNotFoundException - 名稱[類/對象]沒有綁定在此上下文中

Question

有一個問題，因爲處理6小時，但沒有得到解決它。

上午深化發展使用JSF/Tomcat的7/Maven的/ Java 7的

每次我跑我得到這個服務器上的項目動態Web項目：

這裏是我的類項目管理

package ...artzpraxismanagement; 

@Named 
@ManagedBean 
@SessionScoped 
public class ProjectManagement implements Serializable {   
private static final long serialVersionUID = 1L;  
@EJB private Services service; 

和我的服務類

@ManagedBean 

@SessionScoped 
@Local 
public class Services implements Serializable {...} 

我試圖像刪除的WebContent/lib中的Tomcat罐不同的解決方案，但它並不能幫助。我想我的ProjectManagement類不在context.xml中。

我該怎麼做？

Answer 1

默認情況下，EJB和CDI在Tomcat中不起作用，因爲Tomcat只是一個Servlet容器。如果你想使用它們，你必須在真正的Java EE應用服務器上部署你的應用程序，例如JBoss 7,GlassFish 3或TomEE（注意這些是免費的，還有一些像IBM WebSphere和Oracle WebLogic這樣的Java EE 6應用服務器，但是你必須支付以獲取/使用它們）。如果你繼續在Tomcat中部署，你永遠不會成功。

如果您仍然只想使用Tomcat，那麼請刪除所有@EJB和其他Java EE註釋（例如CDI註釋，如@Named）。

順便說一句，請遵循一個關於JSF或CDI的正確教程。您不能同時裝飾爲@Named和@ManagedBean。
