[Opera-users] File upload : It's a MIME boundary problem ... has anyone worked on a workaround ?

[Luís Góis]

When making a file upload to a database using a servlet I made (but using Jason Hunter's classes - www.servlets.com - 
for handling multipart request stuff), I get the following error message and an Exception is raised by Jason's multipart 
classes. What's happening here? It works perfectly with every browser I tested : IE5 ; IE5.5; Netscape 4.75 and 
Netscape 6.0
 
"java.io.IOException: Separation boundary was not specified"

I've tested with Opera 5.11 and 5.0 final for Linux with no successs. Changing browser identification in connection 
properties didn't work either, since it only changes the "User-Agent" header, right? 

Could you give me some info about how to validate Opera boundary field so I can use this browser for file upload?

Thanks in advance
