Hi, we have a service which - in one transaction - does a read and a write to the datastore. We have to assure, that no other request calls the same service as long another thread is in there. In a simple Java app, I just would mark the method as synchronized, but in a distributed manner, that wouldn't work.
Are there any suggestion, how to implement such a locking a clean and safe way?
