I have built an application for creating and displaying an Excel
spreadsheet. It works beautifully when accessed using Mozilla or
Firefox (haven't tested with Netscape) but fails when using MSIE.
It appears that IE refuses to download the file (it also doesn't
recognize the content type) since, when Excel or OOo Calc open, they
complain that the file (in the Temporary Internet Files directory
structure) isn't found. It isn't found for good reason - it isn't there!
From browsing other projects, such as iText on SourceForge, it appears
that IE demands to know how big the stream is (setContentLength).
Unfortunately, I can't figure out how to measure the length to set it
properly. JavaDocs explicitly says that WorkBook.getBytes() "get(s) the
bytes of just the HSSF portions of the XLS file". Apparently, there are
bytes being sent other than these bytes, since stting the ContentLength
to the lenth of getBytes() causes the geckop browsers to fail also.
I would appreciate some insight as to how I might overcome this problem.
