指定した参照は、複数のEJBにマッチした - EJB 3.1

Question

私は6 localhostのスタンドアロンJBossへの私の耳を展開するとき、私は次のエラーを取得しています理由として少し混乱しています：

「java.lang.RuntimeException ：指定した参照（ForecastUtilityLocal '）は、「複数のEJBにマッチした - このEJBはので、どのようつ以上のインスタンスがある@Singletonでアノテートされ

DEPLOYMENTS IN ERROR: Deployment "vfs:///C:/jboss/jboss-6.0.0.Final/server/default/deploy/ear-1.0.0.ear" is in error due to the following reason(s): java.lang.RuntimeException: Specified reference [EJB Reference: beanI erface 'com.ls.forecast.ejb.util.ForecastUtilityLocal', beanName 'null', mappedName 'null', lookupName 'null', owning unit 'ComponentDeploymentContext@23001552{org.jboss.metadata.ejb.jboss.JBossEnte riseBeanMetaData.ExpectedReturnEngineServiceImpl}'] was matched by more than one EJB: [org.jboss.metadata.ejb.jboss.JBossSessionBean31MetaData@63db1386{ForecastCacheManager}, org.jboss.metadata.ejb. oss.JBossSessionBean31MetaData@ee01f6d1{ForecastUtility}].

...詳細は下記を参照してください？あなたが別のEJBに誤っ@Local(ForecastUtilityLocal.class)を入れていない

@Singleton 
@Startup 
@Local(CacheHelperLocal.class) 
public class CacheHelper implements CacheHelperLocal { 

@EJB 
private ForecastModelUtilityLocal forecastModelUtility; 

@EJB 
private ConnectionManagerLocal connectionManager; 

@EJB 
private ForecastCacheManagerLocal forecastCacheManager; 

@EJB 
private ForecastUtilityLocal forecastUtility; 
... 
} 

Answer 1

チェック：それは、例えばのような別のEJBに参照されている

@Singleton 
@Local(ForecastUtilityLocal.class) 
public class ForecastUtility implements ForecastUtilityLocal { 

private static final Logger logger = LoggerFactory 
     .getLogger(ForecastUtility.class); 

@EJB 
private CacheHelperLocal cacheHelper; 
.... 
} 

。
