Java Web project moved from Eclipse to tomact server, path changed, export EXCEL,JXL

I use JXL export Excel, relatively simple, the first I was fixed path can not be selected, very limited, and later changed, and fixed the path when the project on the server, the path is not OK.

The help of the great God on the Internet successfully set the response header, and optionally save the path.

1. Front End

Not with Ajax, like Ajax can't succeed
js$ ("#exportbaofei"). Click (function () {                    window.location.href= "${pagecontext.request.contextpath}/ Exportbaofeiservlet "; });//html<type= "button"  value= "Export waste mode"  ID  = "Exportbaofei"/>

2.servlet
