Subject Re: [fielupload] how much big size file can be handled?
Date Tue, 03 Oct 2006 17:09:59 GMT
When was the Streaming API Added?  I don't seem to have the

FileItemIterator iter = upload.getItemIterator(request);

Method in my 1.1 release.  Was it added in 1.1.1?  When you go to the javadoc link on the
project page it says that is 1.2...
