sync - Async Bridge problem

hi all,

my scenario is simple. i have a ws ho send a interface ID, a java mapping that read flat file, convert into xml and send the response. this XML is save in drive. this file is picked by a file adapter and send the xml to ws as response.

i undertand how to create de BPM bu no how to configure the Interface Mapping.
