Question

我正在尝试通过eclipse连接到我的websphere 7.0服务器中可用的数据源。

以下是代码。

Hashtable<String, String> pdEnv = new Hashtable<String, String>();
        pdEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");             
        pdEnv.put(Context.PROVIDER_URL, "iiop://XX.XXX.XX.XX:YYYY");

        Connection connection =null;



        Context initialContext = new InitialContext(pdEnv);
        DataSource datasource = (DataSource) initialContext.lookup("jdbc/AEDS");

        if (datasource != null) {
          connection = datasource.getConnection("admin","admin"); // DB credintials
        } else {
            System.out.println("hi");
        }

但我在尝试连接时遇到以下异常

Exception in thread "P=365798:O=0:CT" javax.naming.ServiceUnavailableException: A communication failure occurred while attempting to obtain an initial context with the provider URL: 
    at com.ibm.ws.naming.util.WsnInitCtxFactory.mapInitialReferenceFailure(WsnInitCtxFactory.java:2271)
    at com.ibm.ws.naming.util.WsnInitCtxFactory.getWsnNameService(WsnInitCtxFactory.java:1457)
    at com.ibm.ws.naming.util.WsnInitCtxFactory.getRootContextFromServer(WsnInitCtxFactory.java:987)
    at com.ibm.ws.naming.util.WsnInitCtxFactory.getRootJndiContext(WsnInitCtxFactory.java:909)
    at com.ibm.ws.naming.util.WsnInitCtxFactory.getInitialContextInternal(WsnInitCtxFactory.java:581)

我也对与iiop url一起使用的端口号感到困惑，因为我们在同一节点上运行多个服务器，每个服务器都有不同的bootstrap端口。

使用JNDI Websphere连接到JDBC DataSource
