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);
