休眠碎片和JNDI問題

我正在嘗試運行休眠碎片的示例程序。我都用它做，但每當我運行測試程序我得到一個異常休眠碎片和JNDI問題

javax.naming.NoInitialContextException: Need to specify class name in environment or system property

google搜索我才知道，我已經設置JNDI屬性後。。我不喜歡這樣

Hashtable env = new Hashtable(); 
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory"); 
env.put(Context.PROVIDER_URL, "<some-IP>:3306"); 
Context initialContext = new InitialContext(env);

但仍東西不工作:-( 請幫什麼n，其中我失蹤

下面是代碼：

public class SessionFactoryImpl { 

    private static final String SHARD_CFG_0 = "/com/hibshards/config/shard0.hibernate.cfg.xml"; 
    private static final String SHARD_CFG_1 = "/com/hibshards/config/shard1.hibernate.cfg.xml"; 
    private static final String SHARDED_TABLE = "com/hibshards/orm/weather.hbm.xml"; 

    public static SessionFactory createSessionFactory() throws NamingException { 
     Configuration prototypeConfig = new Configuration().configure(SHARD_CFG_0); 
     prototypeConfig.addResource(SHARDED_TABLE); 

     List<ShardConfiguration> shardConfigs = new ArrayList<ShardConfiguration>(); 
     shardConfigs.add(buildShardConfig(SHARD_CFG_0)); 
     shardConfigs.add(buildShardConfig(SHARD_CFG_1)); 

     ShardStrategyFactory shardStrategyFactory = buildShardStrategyFactory(); 
     ShardedConfiguration shardedConfig = new ShardedConfiguration(
       prototypeConfig, 
       shardConfigs, 
       shardStrategyFactory); 
     return shardedConfig.buildShardedSessionFactory(); 
    } 

    private static ShardStrategyFactory buildShardStrategyFactory() { 

     ShardStrategyFactory shardStrategyFactory = new ShardStrategyFactory() { 
      public ShardStrategy newShardStrategy(List<ShardId> shardIds) { 
       RoundRobinShardLoadBalancer loadBalancer = new RoundRobinShardLoadBalancer(shardIds); 
       ShardSelectionStrategy pss = new RoundRobinShardSelectionStrategy(loadBalancer); 
       ShardResolutionStrategy prs = new AllShardsShardResolutionStrategy(shardIds); 
       ShardAccessStrategy pas = new SequentialShardAccessStrategy(); 
       return new ShardStrategyImpl(pss, prs, pas); 
      } 
     }; 
     return shardStrategyFactory; 
    } 

    private static ShardConfiguration buildShardConfig(String configFile) { 
     Configuration config = new Configuration().configure(configFile); 
     return new ConfigurationToShardConfigurationAdapter(config); 
    } 
}

JDNI環境設置正確（provi der URL似乎在使用一個非常奇怪的mysql端口）。請提供有關您的代碼正在執行的更多詳細信息。你想要查找什麼？你在使用什麼應用服務器？還請添加完整的堆棧跟蹤。 – 2009-12-21 06:33:34

我試圖創建一個分片環境。一種演示應用程序。它不使用任何服務器。我的數據庫駐留在兩臺不同的機器上，所以我通過了該機器的IP地址。 javax.naming.NoInitialContextException：需要在環境或系統屬性中，或作爲applet參數或應用程序資源文件中指定類名稱：java.naming.factory.initial \t at javax.naming.spi.NamingManager.getInitialContext （NamingManager.java:645） at javax.naming.InitialContext.getDefaultInitCtx（InitialContext.java:288） – Rites 2009-12-21 06:48:01

請編輯您的問題以添加** full ** stacktrace。 – 2009-12-21 07:00:37

在一個簡單的Java應用程序，你不需要會話工廠的名稱..try刪除你的cfg.xml文件中的名稱並執行它
