The JAA does not directly inspect/regulate/licence FTOs.
It is the job of the national aviation authorities of JAA member states to do that - so for example in the United Kingdom, the UK CAA is mandated (under the JAA) to inspect/regulate/licence FTOs.
If your looking for a comprehensive list of FTOs licenced by the UK CAA, this can be found on the
CAA's website in the form of Standards Document.
