【AAAI 2025】轻量级特征增强新范式！FCM 模块助力小目标检测，即插即用提升模型泛化能力本文介绍了AAAI 2025提出的轻量级特征增强新范式FCM模块，它通过显式分离并双向交互语义与空间特征，有效解决了小目标检测中特征信息失配的核心难题。该模块设计精巧，计算开销极低，能够即插即用式地嵌入YOLO等主流检测网络，显著提升模型对小目标的泛化检测能力，尤其适用于遥感、自动驾驶等对计算资源敏感的实际场景。阅读详情

这是我的java文件中的一个方法
public ResultSet query(String custno)
{
String sql="create temp table cust_jsp_tmp(abc varchar(30))";
try{
executeUpdate(sql);
sql="insert into cust_jsp_tmp select aaa from custom1 where cust_no='"+custno+"' ";
executeUpdate(sql);
sql="insert into cust_jsp_tmp select bbb from custom2 where cust_no='"+custno+"'";
executeUpdate(sql);
sql="select abc from cust_jsp_tmp";
return executeQuery(sql);
}
catch(Exception e){
return null;
}
}
JSP文件如下:
<HTML>
<HEAD><Title>保单详细信息</Title></HEAD>
<body bkcolor=#EEEEEE text=blue bgcolor="#00FFFF">
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="error.jsp" %>
<jsp:useBean id="workM" scope="page" class="custquery.Connect1" />

<%
String custno = request.getParameter("cust");

ResultSet RE=workM.query(custno);
}
%>
<%while(RE.next())
{%>
<%=RE.getString(1)%>
<%}%>
</body>
</HTML>

怎么总是报错:
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 18 in the jsp file: /test.jsp
Generated servlet error:
RE cannot be resolved

An error occurred at line: 20 in the jsp file: /test.jsp

RE cannot be resolved
各位帮我看一下呀!
