Hi,

I got a byte array through web service which contains a file data. I need to get the content/mime type first, then write byte to a ServletOutputStream, how should I do that ?

Thanks.

Doesn't the webservice provide you with that information? There is no handy way to determine which kind of file/mine-type is in a file without meta-data. Although there are libraries that try to analyse the document and provide you with a mime-type.

Hi there,

I realize this is kind of late, but I'm trying to do the same thing and found the following...

http://download.oracle.com/javaee/5/api/javax/mail/util/ByteArrayDataSource.html

Presently, I have to go a different route, but thought this could help someone else.

Regards,

Mike
