请问怎么让JAVA与ORACLE 的数据库连接呀？？高分相送

Question

getConnection(String url, String user, String password) throws SQLExceptionDriverManager.getConnection("jdbc:oracle:thin:@host:1521:db","scott","tiger");

Answer 1

在 Oracle 的 jdbc 子目录中 Demo.zip 有很多范例

Answer 2

到ORACLE 公司的网站上面侃侃了.有一个叫ORACLE JDBC 的书将的很详细的哟.
我补充以下了:forclass("oracle.jdbc.driver");//好象是这么写的吧.
Conntion myconn = DriverManager.getConnection("jdbc:oracle:thin:@host:1521:db","scott","tiger");回复人： bluesmile979(笑着) ( ) 信誉：110  2003-07-13 13:53:00  得分:0

Answer 3

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl";
String user="scott";
String password="tiger";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);String sql="select * from test";ResultSet rs=stmt.executeQuery(sql);

Answer 4

public class ConnectionPool
    {
        private static String driverName="oracle.jdbc.driver.OracleDriver";
        private static String url="jdbc:oracle:thin:@testserver:1521:heliosdb";
        private static String user="helios";
        private static String password="helios";
        public static void setDriver(String driverName)
        {
            ConnectionPool.driverName = driverName;
        }
        public static void setUrl(String url)
        {
            ConnectionPool.url=url;
        }
        public static void setUserPassword(String user,String password)
        {
            ConnectionPool.user=user;
            ConnectionPool.password=password;
        }
        public static java.sql.Connection getConnection()
        {
            java.sql.Connection conn=null;
            try
            {
                Object oDriver=null;
                try
                {
                    oDriver = Class.forName( driverName ).newInstance();
                }
                catch(Exception ex)
                {
                    ex.printStackTrace();
                }
                java.sql.Driver driver = (java.sql.Driver)oDriver;
                java.sql.DriverManager.registerDriver(driver);
                conn = java.sql.DriverManager.getConnection(
                    url, user,password);
            }catch(Exception ex)
            {
                ex.printStackTrace();
            }
            return conn;
        }
    }

Answer 5

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl";
String user="system";
String password="manager";
Connection conn= DriverManager.getConnection(url,user,password);JDBC的配置就是要你有到的WEBLOGIC中配置的，就是控制抬上的配置
另外还要在你的WEBLOGIC中添加ORACLE 的class12。jar的包才可以的
