That's my understanding. For example, if your objects have collections, when you add a new object to the collection its id isn't set, then after you persist the outer object the new object is persisted and its id is set. jopaki wrote: Using GAE/J JDO, must one implement equals/hashCode based

Re: [appengine-java] Re: A running app does not detect newly created files.

Since app engine does not allow file writing, it probably does not expect any new file during run time. That's why you see the new file only after restarting the server. To "write new file" in app engine, I would think it as "put new file content into datastore". -aj On Thu, Jan 14, 2010 at 9:53 A

Threads do not end when they finished serving a request. Instead they will catch up another request in the queue and serve it. So basically at the end of your service method of your servlet you should explicitly set the value of your ThreadLocal to null, prefferably in a finally block. 2010/1/14
