If you are using Eclipse, this can typically be fixed by making a small change to one of your JDO enhanced classes (like, hit space and then delete the space), save the file, and try re-sending the app to Google.

[appengine-java] Re: GAE down? Response Error 500
Well, my primary servlet that loads data from the datastore still breaks, and spits out a 500 Server Error when I run it manually: http://showsort.appspot.com/showsort/list If it works, it shouldn't show anything at all, because it is a GWT- RPC driven servlet. http://showsort.appspot.com There are 2 things which have async calls run. First is a graphic update which draws a black line (IE still doesn't work for this... other browsers do though). Second is a list of sorting algorithms, retrieved from the datastore, which appears above the Start button on the screen. This never happens, because I'm getting a 500 Server Error consistently whenever it attempts to be run. I've re-uploaded my app on the off chance that it was a bad update or something last time, and no change. It makes my app, well, completely useless if I can't access the datastore at all...

Now, I've checked my web.xml file, and it seems to be correct, I've checked the Service interface in my GWT code and it is pointing to the correct path to access the servlet, and I've rechecked my code that calls the GWT-RPC servlet, and the servlet (and servlet facade), it all is fine. There just doesn't seem to be any connection going on here. Now, I *know* that going to a GWT-RPC servlet RemoteServlet doesn't work... but I'm getting 2 different kinds of responses, depending on my servlet. If I go to: http://showsort.appspot.com/showsort/display -- in Mozilla Firefox, I get a blank page. I expect this, as it doesn't have a GET or POST interface, and that's fine. If I go to: http://showsort.appspot.com/showsort/list -- in Mozilla Firefox, I get a 500 Server Error page. This is strange to me, and unexpected. The main fundamental difference between the two is that the list servlet requires datastore functionality, the display servlet only does when called upon to generate a full set of display updates for a selected sorting algorithm... only possible if I get the list of available sorting algorithms from the list servlet, which isn't happening.

Oh, I also have seen these occasionally for the past 2 days, suddenly: # 1. 09-04 10:37AM 58.844 /showsort/list 500 10129ms 0cpu_ms 0kb Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.0 (KHTML, like Gecko) Chrome/3.0.195.6 Safari/532.0,gzip(gfe) See details 207.166.99.104 - - [04/Sep/2009:10:38:08 -0700] POST /showsort/ list HTTP/1.1 500 0 http://showsort.appspot.com/showsort/ 099466D0895E48EB4E5CF7AD38C5FA29.cache.html Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.0 (KHTML, like Gecko) Chrome/ 3.0.195.6 Safari/532.0,gzip(gfe) showsort.appspot.com 2. W 09-04 10:38AM 08.974 Request was aborted after waiting too long to attempt to service your request. Most likely, this indicates that you have reached your simultaneous active request limit. This is almost always due to excessively high latency in your app. Please see http://code.google.com/appengine/docs/quotas.html for more details. But they are extremely sporadic when/if they appear. I have 2 (just 2) servlets which may be called simultaneously. The list one automatically re-sends to check for an update every 10 minutes, while the display one is called when someone presses the send button (and only if there actually is a list of radio buttons to pick from, retrieved from the list servlet). I think it is peculiar that something as simple as my little app could have overwhelmed my quota. Especially as my Quota page completely disagrees and shows I'm well under my quota in all regards. My app's latency isn't too high, I've minimized it to where it generally has about 3 - 4 seconds at most (I think the list might take 6, but I'm planning on working on that). There was a point that the display servlet was taking incredibly long, but I've made massive headway on reducing that. So I'm shocked, completely, if my quota somehow was exceeded, especially as I don't see any evidence of it. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: GAE down? Response Error 500
I set up a doGet method on my list servlet, which should just display the list of algorithm names that is retrieved from the datastore. There are 13 items in the list, not much. http://showsort.appspot.com/showsort/list This way, you don't need to use the rest of the app to see this. I'm getting a 500 Server Error. There has been two times that I have gotten more than just the initial request line logged in the Admin Panel's logs. Both times, it halts on the step where it is trying to read from the DataStore. My code to do that worked just fine before the 1.2.5 change 2 days ago.
