明明导入了包..但是还是报QueryRunner cannot be resolved to a type

dbutils 这是个USER包...导入了项目...
以下是导入的包<%@ page import="java.util.*"%>
<%@ page import="javax.sql.*,javax.naming.*,com.zry.util.*"%>
<%@ page import="org.apache.commons.dbutils.handlers.*"%>
<%@ page import="java.text.SimpleDateFormat"%>
<%@ page import="org.apache.commons.dbutils.QueryRunner"%>

以下是其中的一段代码:
Context initContext=new InitialContext();
DataSource ds=(DataSource)initContext.lookup("java:/comp/env/jdbc/oraclezry");
QueryRunner qr=new QueryRunner(ds); result=qr.update(sql,parm);

下面是报错:An error occurred at line: 26 in the jsp file: /addMessageHandler.jsp
QueryRunner cannot be resolved to a type
23:
24: Context initContext=new InitialContext();
25: DataSource ds=(DataSource)initContext.lookup("java:/comp/env/jdbc/oraclezry");
26: QueryRunner qr=new QueryRunner(ds);
27: result=qr.update(sql,parm);
28:
29: if(result==0){
