用jsp调用javaBean连接数据库

我是这样连接的。  
  opendb.java/class可以连接上数据库  
  代码：  
  package   com.sun;  
  import   java.sql.*;    
  public   class   opendb  
    {    
  Connection   con=null;    
  Statement   stmt=null;  
  ResultSet   rs=null;    
  String   user="syw";  
  String   password="198001";  
  String   query   =   "select   *   from   test";    
  String   url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=jsp";  
  public   opendb()  
  {  
  try  
    {    
      Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");  
    }   catch(java.lang.ClassNotFoundException   e)    
        {    
          System.err.print("ClassNotFoundException:   ");    
          System.err.println(e.getMessage());    
        }  
  }  
  public   ResultSet   executeQuery(String   sql)  
  {  
  rs=null;    
  try   {    
      con   =   DriverManager.getConnection(url,user,password);    
      stmt=con.createStatement();  
      ResultSet   rs   =   stmt.executeQuery(sql);  
      }   catch(SQLException   ex)      
          {  
              System.err.println("SQLException:   "   +   ex.getMessage());    
          }    
  return   rs;  
  }  
  }    
  但是用jsp调用时出现这样的错误，不能正常现实！不知道是什么原因？  
  错误：  
  A   Servlet   Exception   Has   Occurred  
  org.apache.jasper.JasperException:   Unable   to   compile   class   for   JSPNote:   sun.tools.javac.Main   has   been   deprecated.
