You know what?
Its a paid plugin.
You need to purchase if you use it in commercial apps
I just realized that as I started looking into it for my own application.
I wonder .. can an APEX REST service be used as the receiving point for the files?
You'll want to record app id, page id, and session id along with filename and the actual BLOB of the file in a table (not WWV_FLOW_FILES)
I know about that existing plugin " Item Plugin - Multiple File Upload"
But I doesn't work in IE and has only basic features. Licence for commercial use is also needed. I would like to use some existing jQuery plugin. There are many of these plugins with nice features. And only one problem is that I need to create some server side process/servlet/script.. that can recieve HTTP request, get files from it and stores them into DB.
APEX REST webservice is also not solution for me because I am not using Apex Listener. I am using EPG and Apache server as HTTP proxy
I solved it using a "dirty" solution. I already have Apache server as proxy and for caching purposes in my environment. So I installed PHP into it and create PHP script to receive specific POST requests with files and stores them into DB. It is not clean solution, but I think that EPG server and APEX have limited functionality in this way.
