Hi,
I think there are samples of this on the net but basically you need to:
1 – create a receive port
2 – create a FILE receive location connected to port in step 1
3 – set the pipeline to pass through
4 – create a send port
5 – set a filter to BTS.receiveportname = the name of your port in step 1
6 – set the transport type to FTP and configure the FTP send adapter settings.
7 – start receive and send ports.
(Easiest way to do all of this is in the Biztalk Server administraiton console and you can use the default application 1 project…)
hope this helps as a beginning…
