贼奇怪的一个巨大问题!!
jdbc odbc 在命令行下连接数据库成功
在jsp页面下连接不成功! 我郁闷
我直接发源代码.
命令行下
import java.sql.*;
public class Shell
{
public static void main(String[] args)
{
String sql;
Connection conn;
Statement stmt;
ResultSet rs;
try
{
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=university ";
String user= "sa ";
String password= " ";
conn= DriverManager.getConnection(url,user,password);
stmt=conn.createStatement();
sql= "select * from Student ";
rs=stmt.executeQuery(sql);
while(rs.next())
{
System.out.println(rs.getString(1));
System.out.println(rs.getString(2));
}
rs.close();
stmt.close();
conn.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
页面下!!
