Hi Marc,
You can extend AllPermissionFileService and override the following method:
FileContents storeFile(final String filePath, final InputStream in) throws
ServiceException {}
Or
You can implement your own file service.
Source code for AllPermissionsFileService is part of ULC release and it can
be found in:
<ULCInstallDir>\base\src\ulc-base-trusted-src.jar
At the end of this mail is a snippet which demonstrates how you can add an
extension to the file name.
I hope this helps.
Thanks and regards,
Janak
