[appengine-java] Re: Eclipse hangs at startup, Ubuntu

Did anyone ever resolve this in a consistent way? I recently upgraded from OSX 10.5 to 10.6, and now my Eclipse (Cocoa 64-bit, as I was using before) hangs on most startups. I see the "Updating MyProje... - 1.3.1" in the bottom right corner and the entire window is locked up. Only way out is to

Hi Praseed, my application uses the google spreadsheet api for importing data. I have learned the following lessons from it: 1. performance is not great. the api runs over http and is limited to GAE request timeout (5 to 10) seconds. on some cases a single request exceed this time and you are requ

You get this message when you app is still starting while other requests come in. The only current solution is to reduce start up time - pinging is not a satisfactory solution because you still get frequent "loading requests". With Guice I was able to reduce star up by using a non AOP ver
