我快疯了!大家快救救我!
那位大哥能给我个websphere下的应用程序如何连接数据库的实例,求大家了,怎么也连不上,代码如下
public static Connection getConnection(){
final String CON_JNDI_NAME = "jdbc/safe";
Connection con = null;
try{
//Context initCtx = new InitialContext();
Hashtable env = new Hashtable();
//Class.forName("com.ibm.Websphere.naming.WsnInitialContextFactory").newInstance();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.Websphere.naming.WsnInitialContextFactory");
//env.put(Context.PROVIDER_URL,"iiop://localhost:900");
InitialContext initCtx = new InitialContext(env);
DataSource ds = (DataSource)initCtx.lookup(CON_JNDI_NAME);
con = ds.getConnection();
String date ;
date = (new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS")).format(new java.util.Date());
System.out.println("DBMANAGER getConnect-->"+date);
}catch(Exception e){
e.printStackTrace();
}
return con;
}
连接配置在websphere里面测试成功!请大家指教1!万分感谢!!!!
