java.lang.IllegalStateException
前台点击导出excel按钮跳到这个页面之后执行we.ExcelZone("111.xls",response.getOutputStream());这一句的时候报错：严重: Servlet.service() for servlet jsp threw exception

我该怎么解决啊，求高手。 --------------------编程问答-------------------- jsp完整代码如下：
<%@ page contentType="application/vnd.ms-excel" language="java" import="java.util.*,com.ps.action.admin.AreaAnalysis"import="com.ps.entity.heatAcum"import="com.opensymphony.xwork2.ActionContext" pageEncoding="GBK"%><%
response.reset();
response.setHeader("Content-Disposition","attachment;filename=test123.xls");
response.setContentType("application/vnd.ms-excel");
System.out.println("bbbbb");
AreaAnalysis we=new AreaAnalysis();
we.ExcelZone("111.xls",response.getOutputStream());
%> --------------------编程问答-------------------- response.reset();
这句问题。 --------------------编程问答-------------------- 这句去了还是报错，问题在这一句：we.ExcelZone("111.xls",response.getOutputStream()); --------------------编程问答-------------------- 坐等答案。求高手。 --------------------编程问答-------------------- 嗯。
jsp编译的结果会编译出out.write()，与response.getOutputStream()冲突了。
we.ExcelZone("111.xls",response.getOutputStream());
在这句后面加下面两句：
out.clear();
out = pageContext.pushBody(); --------------------编程问答-------------------- we.ExcelZone("111.xls",response.getOutputStream());
请问111.xls是在哪？C盘？D盘？E盘，你确定这里不用给个绝对路径，例如 c:/111.txt ？？？？ --------------------编程问答-------------------- 嗯，jsp编译的时候，会编译出out.write（），它与response.getOutputStream()冲突了。
在最后，即we.ExcelZone("111.xls",response.getOutputStream());后面加：
out.clear();
out = pageContext.pushBody(); --------------------编程问答-------------------- 还是不行啊，我对应的那个 ExcelZone方法是这样的：
public String ExcelZone(String str ,OutputStream out)throws Exception{
...
}
是不是这个out的问题，该怎么处理？ --------------------编程问答-------------------- 一天了，就没有人知道吗？？？ --------------------编程问答-------------------- 一天了啊，高手都去哪了？？？ --------------------编程问答-------------------- 有没有搞定呢？
补充：Java , Web 开发
