Yes, as a hivemind service. Didn't know of the different models tough.

Re: How to synchronize a service
Hi If you are refering to a "service" as a hivemind service, then you can hava look on the service modles which are threaded, pooled, primitive and singleton. Singleton service model will ensure that only one instance of service exists. After you know that you can synchronize part of the code which is responsible for checking and creating directories. But I guess better approach would be to put non-multithreaded part of your functionality to the singleton service and have other threaded services reading data prepared by singleton service.

How to synchronize a service
Hi all, I'm using tapestry 4.0 and have a service that what roughly does is create a PDF file in the tmp dir if it does not exists. If the file exists or after its creation the service returns its contents to the client. Now I'm worried about synchronization issues in this code. Mi first idea was synchronize the method that looks for the file and creates one if none exists, but this will not work if multiple instances of the service are concurrently running. So, can I safely assume that there is only one instance of the service running?, I think not but wanted to be sure. If there may be many instances of the service running, is Ok to synchronize on some global object? (global as in
