求救：数据连接池的时候出现问题

ad1227 2006-04-01 09:57:28

用Sun one Application Server 7 配置了一个数据库连接池，写了一小段程序测试是否成功，可是怎都连不上，有错误。请高手帮忙看看。

Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://192.168.0.205:3700");
//System.out.println(Context.DNS_URL);
Context initialContext = new InitialContext(env);
System.out.println("haha");
DataSource ds = (DataSource)initialContext.lookup("jdbc/cwbase15");
conn = ds.getConnection();
上面是程序，下面是错误：

javax.naming.NameNotFoundException [Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0]

显示的是DataSource ds = (DataSource)initialContext.lookup("jdbc/cwbase15");这句话出错

大家帮忙看看啊，急着用。。。也不知道什么地方出错了。
