Is file transfer extension support or not?

Hello All

In my application i want to transfer file from one user to another.i have read XEP-0234,XEP-0096 extensions doc.

when i m trying to find out whether services supported or not.it always says “feature not implemented”.

My application is web based.

In Application i have used,

-Openfire Server

-Strophe.js Javascript

i dont know where is the problem.its in openfire or strophe.

i can send file if any namespace(e.g. bytestream,ibb,si etc.) is support.

this is my last feature that i have to implement.

Please Help…

Any kind of help will be great appreciate.
