Subject RE: [OFF TOPIC] ServletOutputstream Issue
Date Mon, 14 Apr 2003 18:30:44 GMT
are you opening the URL in Excel or IE? 

if you are using IE try these:
1. does your URL for the servlet end in xls? IE handles PDF this way - I'm
not sure if xls would be the same. try adding ?x=xls to the end of your URL
and see if that works.

2. Are you setting the content-length? This may help.

3. Set the content-disposition :
response.setHeader("Content-Disposition", "attachment;filename=abc.xls;");

hope that helps,
