The MIME type of while uploading .dbf files
Hi ,
I am trying to do a restricted file upload .
I have used
<interceptor-ref name="fileUpload">
text/plain,application/vnd.ms-excel,application/dbf,application/dbase,application/x-dbase,application/x-dbf,zz-application/zz-winassoc-dbf,application/x-msdownload
</interceptor-ref>
For me .txt files and .csv files are working fine but .dbf(i.e Microsoft
Visual FoxPro Table type ) files are not working .
The error is
Content-Type not allowed: upload
"upload_abfbeb3_12033a3b84f__7f9e_00000002.tmp" application/octet-stream.
Please suggest me what should put for the content type for .dbf .
If i put add the application/octet-stream content type then it works , but
at that time it allows .exe files also which i don't what . Please suggest
me what should i do .
With Regards
Aruabh

This reminds me of a Jira ticket sometime back, which was caused by
Safari picking some weird contentType. As Greg said, defining the
contentType is up to the browser and it is unreliable at best (and
useless at worst)

is picked by your browser using whatever magic it has to determine the file
type. I just did a test and uploaded a .mp3 file using IE and got a
contentType="audio/mpeg" which looks correct. I uploaded the same file with
Firefox and got a contentType="audio/x-amzaudio" huh? I have an Amaozn audio

So the lesson is you can't count on the browser picking the correct type,
and different browsers will pick different types (who knows how your user's
browser is configured or what it will pick for a given file.)
With respect to your question, your browser likely doesn't know what a
".dbf" file is (why would it?) and it probably defaults to
"application/octet-stream" which simply mean "unknown binary data".
I would avoid the "allowedTypes" since you can't count on them being
accurate and do my own validation in the action class.
