[appengine-java] "appcfg.sh update" suddenly doesn't work

[appengine-java] HTTPRequestPoster - problem
Hi all,
I'm working in Eclipse 3.5 using the most recent Google plugin 3.5.
I am attempting to use HTTPRequestPoster to send post data from an app
(with the server running on http://localhost:/) to a Tomcat server
running on port 8080 the same machine (MacBook pro).I can
successfully send info as a Get (and get a response) with the
following code:
String urlString = "http://localhost:8080/tester/TestService";;
String getParams = "id=mmsend&grp=Dummy&msg=dummy
message";
HTTPRequestPoster rp = new HTTPRequestPoster();
String responseToGet = rp.sendGetRequest(urlString,
getParams);
System.out.println("Response-toGet="+ responseToGet);
However, where callingRequest is a fully instantiated Bean with String
fields and one ArrayList, the following code doesn't work
because it doesn't insert any Post data in the request:
StringWriter sw = new StringWriter();
try {
HTTPRequestPoster.postObject(callingRequest, urlString, sw);
} catch (Exception e) {
e.printStackTrace();
}
String ResponseToPost = sw.toString();
In the doPost method on the receiving Tomcat, the following code shows
0 bytes:
InputStream inStream = request.getInputStream();
int nbytes = inStream.available();
System.out.println("# bytes available = "+nbytes);
What is the problem here?
Thanks in advance,
Ken Bowen

[appengine-java] Re: task cancel, task insert, url fetch delay, servlet context listener
I mean programmatically. Basically I was expecting something like Queue.purgeAllTasks(). It calls contextInitialized but not contextDestroyed. Isnt it a little strange ? I cannot persist something I am doing in memory for example based on context init-destory cycle. So everything has to be done per request (I guess as expected from the appengine.)

[appengine-java] Re: Question about inbound mail.
I would like to get the joy directly from Google Engineers (its a weird answer, not covered in the docs but directly related to the GAE setup), but you are right. Its not the first time the Google Support sucks big time... I'll try elsewhere.

[appengine-java] Re: App Engine cold starts and overly aggressive cycling
Ikai, Me too I can report an improved response time and no datastote timeout exceptions the past couple of days. I have no measurements so far, but the improvement is noticeable. I'll certainly keep watching and let you know of any relevant issues. Thanks! Jorge Gonzalez On Jan 22, 9:10 pm, James Cooper wrote: > Ikai, > > Great news.

Re: [appengine-java] task cancel, task insert, url fetch delay, servlet context listener
have you tried removing the queue.xml entry and updating? Yes, apps are reloaded frequently and every time your listener will be called.

I can do it in other ways -actually I did-, but I wonder if there is an easy way to do it. Other question is it seems to me like url fetch is not realtime. Can it be the case ? What I do is, I disable access to some URL, but the effect of this appears some seconds or tries later. Two last question is, it seems like ServletContextListener.contextDestroyed is not called, is it right ? Also, I experience some contextInitialized calls for same application (lets say 10 per day).

No idea, but if you're not getting any joy, maybe try at www.stackoverflow.com - there should be a bit more motivation to help because it's points- based.

[appengine-java] Re: generating sequential ids
What you could do is something like this:
public class Employee {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.INCREMENT)
private Long id;
@Persistent private String department;
@Persistent private String firstName;
@Persistent private String lastName;
}
start with id 1, and goes on untill they have reached 2^32 - 1.
Should do the trick.
