In my application, I get values from captors Each value has a 5 minute validity. Each read from a captor cost a lot, so I've tried to put it in the GAE cache
My code (JCache or low level api) is working with the cache as long as I don't use the exoiration delay. When I use the expiration delay, it works fine as long as the expiration delay isn't spent. After, a get(key) on the cache always gives null and a put(key,value) doesn't change that. The same problem seems to be describded here http://groups.google.com/group/google-appengine-java/browse_thread/thread/4e562762f13d932e/a974365a918b279d?lnk=gst&q=JCache+expiration&pli=1 and in other messages on the web Here is a view of my code on the low level API key = num; foo = (String)cache.get(key); if (foo == null) { foo = ..../* get the value */ cache.put(key, foo, exp, MemcacheService.SetPolicy.SET_ALWAYS); } resp.setContentType("text/xml"); resp.getOutputStream().print(foo); } where exp is declared as a global by static Expiration exp = Expiration.byDeltaSeconds(300); -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
