java怎样联接数据库

[sowill]

在jbuilder6中，怎样和远程的sql server联接

---------------------------------------------------------------

package jsp;
import java.sql.*; // JDBC package
public class sql_data {
String url = "jdbc:inetdae:192.168.2.70?sql7=true"; // use your
hostname and port number
String login = "sa"; // use your login here
String password =""; // use your password here
public Connection connection = null;
public Statement st = null;
public ResultSet rs = null;
public sql_data(){
　try {
　　Class.forName("com.inet.tds.TdsDriver").newInstance();
　　DriverManager.setLoginTimeout(10);
　} catch(Exception e) {
　e.printStackTrace();
}
}

public void sqlclose() {
　try {
　　st.close();
　　connection.close();
　}
　catch(SQLException ex) {
　　System.err.println("sqlclose: " + ex.getMessage());
　}
}

public ResultSet executeQuery(String sql) {
　try {
　　connection = DriverManager.getConnection(url,login,password);
　　connection.setCatalog( "register");
　　st = connection.createStatement();
　　rs = st.executeQuery(sql);
　}
　catch(SQLException ex) {
　　System.err.println("aq.executeQuery: " + ex.getMessage());
　}
　return rs;
}
}

楼上的方法可行！！
还有这个
import java.io.*;
import java.util.*;
import java.sql.*;
import java.lang.*;

public class DBConnect {
private String jdbcDriver=null;
private String jdbcURL=null;
private String userName=null;
private String password=null;

public DBConnect() {

jdbcDriver="sun.jdbc.odbc.JdbcOdbcDriver";
jdbcURL="jdbc:odbc:shihong";
userName="system ";
password="manager";
}
public Connection getConnection(){
Connection connection=null;
try{

Class.forName(jdbcDriver);

connection=DriverManager.getConnection(jdbcURL,userName,password);
}catch(Exception e){

System.out.println(e);
}
return connection;
}
}
