(1)Weblogic JNDI configuration notice:the JNDI Name in Weblogic is very importation. It’s not a set for JNDI,but the JNDI name which in JNDI set. (2)Remember restart the Weblogic server when u change the Weblogic’s configuration,else ,it should be error when use this configuration in JBuilder. (3)The steps for connect database through Weblogic: 1)Set datasource in Weblogic 2)Get datasource in program 3)Connect the datasource 4)Do SQL operation in Program. 5)Release all Like this: try { // 获得WebLogic ServerJNDI初始上下文信息 ctx = getInitialContext(); // 建立数据源对象 ds = (javax.sql.DataSource) //通过JNDI上下文查找JDataStore数据源,如果你是用的Jdatastore //ctx.lookup("dsJDataStore"); //通过JNDI上下文查找Oracle9i数据源 ctx.lookup("LSIdbSource"); …. //建立连接 myConn = ds.getConnection(); // 建立语句对象 myStatement = myConn.createStatement(); //建立结果集对象 //建立JDataStore结果集对象 //myResultSet = myStatement.executeQuery("SELECT * FROM employee"); //建立Oracle9i结果集对象 //myResultSet = myStatement.executeQuery("SELECT * FROM SCOTT.EMP"); myResultSet = myStatement.executeQuery("SELECT * FROM LSI.TEST"); …. if (myStatement != null) { myStatement.close(); } if (myConn != null) { myConn.close(); }
