怎么会是NoSuchMethod？？？

[jinsu_st]

String filepath = "../webapps/amis/exportFiles/" + filename;

把路径写成绝对路径吧

或者使用System.getProperty("user.dir")获取应用路径

String filepath=System.getProperty("user.dir")+"/exportFiles/"+filename;

建议先把System.getProperty("user.dir")看看你的路径是什么，然后加上相应的路径。

com.jrosion.business.service.IAtEmployeeWagesService.getErrorMsg()

找不到这个方法,或者方法参数不对, 和 JXL没关系

各位兄弟们，我写成下面的样子就可以了，xp下面也可以
String filename = request.getSession().getId() + Math.random()
+ ".xls";
String filepath = getServlet().getServletContext().getRealPath(
"/exportFiles/" + filename);
