Workaround described in the above blog post is to update the charset to us-ascii replacing UTF-8. This seems to work. But with limited file processing capabilities of peoplecode, this workaround is not a simple solution.
I also verified the mime-type mapping in the web.xml file in the webserver. Please find below the .xls mime-type mapping in the web.xml file.
1.How do I force the browser to open the excel output file using either Excel plugin or Excel Application instead of displaying it as HTML page?
2.If not the above, how can I force the system to promt the user to save the file as Excel file instead of mhtml?
