File upload: not identified content type.

[vijay shanker]

Hello friends;

I am using commons file upload library to upload files. I have been noticing
some time my library does not get file content type correct. For such a file
it saves *application*/*octet*-*stream. *

Can any body describe how it does happens?

If some of you have known for such a situation. Please share the
information.

AIUI it gets it from the request headers:

Please validate on client side if file is uploaded and in serverside side
check for extension of file before checking application/octet-stream


if(file!=null){
                strFileName = file.getFileName();
                stContentType = file.getContentType();

 }

if ( strFileName != null && !strFileName.trim().equalsIgnoreCase("")) { //if
filename not null
 
strExtension=strFileName.substring(strFileName.lastIndexOf(".")+1);
strExtension=strExtension.toUpperCase();
if("application/octet-stream".equalsIgnoreCase(stContentType)
  ){
/////process///
}
}

Thanks guys;

I am using spring-mvc for my web application. So have been looking in to the
spring lib to get some thing relevant. But sorry to say; I have got no
results.

I think finding with file extension will do and will save me every time.

May be spring lib has some thing to support me; any body can point!
