I do this by implementing an independent class as the phase listener. When a phase callback occurs, it stores the current phase in a static ThreadLocal variable. A single HTTP request is always serviced in a single thread, so this works nicely. A static method is then provided for any code that wants to query the current phase (for the current thread): String phaseId = PhaseTracker.getCurrentPhase(); Regards, Simon
