We need to create a puglin that allow us to export automatically registrations from Smart Client.

I need to make a java application that allows me to automatically export video and audio from the smart client every 24 hours. I downloaded the SDK kit in which I found the 4 wsdl, I would like to know, would someone be able to tell me, if this is feasible, which methods, among those found within the WSDL, should I use in order to automate the export.

When doing a Smart Client plugin to do export I think you should first explore the Smart Client Export plugin sample.
