I am rather experienced with the FileReference class but have come across a major problem. Basically, the file uploading just stopped working. It works for me in IE (though I still receive the "Error 203" File I/O Error which on the server is a 403 'not authenticated). It does not work at all in Firefox for me (same error). So it is clear Tomcat is not receiving the jsessionID header (which I validated with a packet sniffer). IE is receiving it which is why that works though I'm confused as to why I get the error if the upload took.
I am using Tomcat to handle my uploads. Basically, we use a JSP for the user to login (which adds the jsessionID header) and then redirect the user to Flex app (.html and .swf) upon valid login. From there, any upload should (and did) pass that header. But that stopped working and now the errors. Using a packet sniffer, I see the jsessionID is not getting included in the FF POST request. I have seen blogs to tack it on the parameter request but that will not work for me (it has to be a header). This had worked in the past so I am not sure what went wrong. I was on the prerelease version of FB3 (pointing to 2.0.1 hotfix 3)...so i thought it might be my Flash player. I reinstalled the Flash Players for IE and FF from the main Adobe site and no luck. I tried building the swf from FlexBuilder 2...no dice. Really at a loss here. Any thoughts from anyone? Cheers, Kevin
