java当中JDBC当中JNDI用来查找dataSource的例子

[学习笔记]

8.JNDI用来查找dataSource的例子：

import javax.naming.InitialContext;
import javax.naming.Context;

import com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource;

import java.util.Properties;
import net.sourceforge.jtds.jdbcx.*;
public class ClassPut {
        public static void main(String a[]) {
                try {
/*                  JtdsDataSource dataSource=new  JtdsDataSource();
                        dataSource.setServerName("localhost");
                        dataSource.setDatabaseName("NorthWind");
                        dataSource.setUser("sa");
                        dataSource.setPassword("1234");
*/
                    MysqlConnectionPoolDataSource ds = new MysqlConnectionPoolDataSource();
                    ds.setURL("jdbc:mysql://localhost:3306/test");
                    ds.setUser("root");
                    ds.setPassword("1234");                      
                        
                        
                        Properties prop = new Properties();
                        prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
                                        "com.sun.jndi.fscontext.RefFSContextFactory");

                        Context ctx=new InitialContext(prop);
/*here the following statement writes a file .bindings under the f Disk. because this project is under the f disk.*/
                        ctx.rebind("abc",ds);


                } catch (Exception e) {
                        e.printStackTrace();
                }
        }
}
上面的程序只是存入硬盘，想查找出来得用下面的程序：

import javax.naming.InitialContext;
import javax.naming.Context;

import com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource;

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
import net.sourceforge.jtds.jdbcx.*;
public class ClassGet {
        public static void main(String a[]) {

                try {
                        Properties prop = new Properties();
                        prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
                                        "com.sun.jndi.fscontext.RefFSContextFactory");
                        Context ctx=new InitialContext(prop);
