都不看报的错误啊，不是提示47行有错误吗

org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/list.jsp at line 47
.....
javax.el.PropertyNotFoundException: Property 'empid' not found on type java.lang.String

提示找不到“empid”属性，猜测是不是items中的EL表达式漏了**$**啊，写成这样试试：

 <c:forEach items="${requestScope.empList}" var="emp">
