Re: [appengine-java] no async queries on AsyncDatastoreService for 1.4.0?
Hi Max,
Could you please provide input on the following design:
We design for DataSource redundancy. For this we've built a flow which
obtains data from 2 sources: First from GAE DataSource using PreparedQuery
and if that fails (0.5sec timeout) from our backup service feed which we
access using URLFetch (auto scaled EC2 nodes).
We strive for maximum performance, So we plan to issue async call to each of
the data sources and later when the data becomes required poll the 2
sources, using the first one available.
As for the URLFetch service, we will use this patten:
Future f = fetchService.fetchAsync(request);
...
if(f.isDone()) { ... }
But for PreparedQuery.asIterator(), I'm not sure how this is implement on
your side. I would love an answer confirming that this code will not block
on hasNext() (While datasource is asynchronously getting results)?
Iterator iterator =
getAsyncDatastoreService().prepare(findGeoIP).asIterator();
if(iterator.hasNext()) { ... }
Thanks for the insights.
Maxim.

Re: [appengine-java] no async queries on AsyncDatastoreService for 1.4.0?
Currently hasNext() will block on the first batch of results. There is
currently no way to do what you are asking in Java.

Re: [appengine-java] no async queries on AsyncDatastoreService for 1.4.0?
Thank you for the information.
We kinda expected that the current implementation will block...
In case anyone wonders our current worked out design is as following: Do
async get to EC2 (takes ~270ms) and right after that do blocking get to
datastore (with timeout of 300ms).
Because we know URLFetch to ec2 takes ~270ms and is async we get to enjoy
both worlds even with a blocking DataStore:
Option A: Datastore has no problems, meaning that it will reply to
PreparedQuery with 15ms. In this case we don't bother with the async call we
just did and just continue normal flow.
Option B: Datastore has problems, and will block. In this case the 300ms
query will time out, after which we will attempt to access the Future.get()
of URLFetch where we expect to have a result.
So... If today we did (at maximum) 500ms datastore get + 270ms URLFetch get
= total of 770ms just for the query after I get implemented we should be
doing (at maximum) query in 300ms.
Kinda of cool.
Maxim.

[appengine-java] JSF: sudden ViewExpiredException on GAE
Hello all,
I've suddenly stuck with JavaServer Faces application stopped working
at GAE. Investigation shows that view state is not being stored in
session correctly.
What I also found out is that when the first request is being done
(i.e. with clean session), ajax requests are working; but when another
view is requested, ajax is not working there anymore. I assumed this is
because updated view state is not being stored, and tried to make a
slight change:
a) as is:
Map statesMap = session.get("state");
if (statesMap == null) {
statesMap = new HashMap();
session.put("state", statesMap);
}
statesMap.put("...", state);
//force update in cluster
session.put("state", statesMap);
b) with the slight change:
Map statesMap = session.get("state");
if (statesMap == null) {
statesMap = new HashMap();
session.put("state", statesMap);
}
statesMap.put("...", state);
//force update in cluster
session.remove("state");
session.put("state", statesMap);
However the solution is not very good, so can please someone help with
the problem?
P.S. Runnable demo example is available here:
http://java.net/jira/browse/JAVASERVERFACES-1886

[appengine-java] Re: 1.3.8 Console Logging Issue
Yep, still not working as in the past.
So here goes my fundamental question: is it a bug or a feature (http://
globalnerdy.com/wordpress/wp-content/uploads/2007/12/

Please answer!

Re: [appengine-java] JSF: sudden ViewExpiredException on GAE
Well, I'll take a wild stab at it since I don't know Java Server Faces, but
since you say it was working and now has stopped. Do you have
true in your appengine-web.xml? If not,
add it. As of 1.4 this is now being adhered to whereas prior to this
sessions were enabled regardless. So perhaps even with sessions not enabled
you are able to get a session object from the servlet context for that
initial request but the appengine isn't saving state to the datastore so the
next request gets told that the requested session identifer is not
valid/expired.

Re: [appengine-java] Blobstore Code Works On Dev Server, Not Production
You can solve that handling GETs and POSTs with a common handler.
void doGet(... req,... resp) {
handle(req, resp);
}
void doPost(... req,... resp) {
handle(req, resp);
}
void handle(... req,... resp) {
}

[appengine-java] Re: HtmlUnit support on GAE for GWT crawlability
Always On has made an interesting twist. If you want this to work for free, then ATM Gal Dolbers method appears to be the best at this stage. But with Always On not only do sites with low traffic now get faster start ups... It also means that the URLFetch timeout problem for Ajax Crawlable appengine sites using GWT, for example, has been lessened. No longer are you waiting more than 10 seconds to fire up another instance so you can fetch a snapshot. This means that the fetching of dynamic content by Googlebot on gwt based applications can be done in real time rather than relying on fetching dated snapshots from another application. So now you have choice. I've now updated my site and blog to include this and, on the surface, everything seems good. Time will tell. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Blobstore Code Works On Dev Server, Not Production
So, I did that, but now I am receiving the following error:
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; line-height: 19.0px; font:
13.0px Courier New}
java.lang.IllegalStateException: Must be called from a blob upload
callback request
Plus, I needed to change my .jsp form code to a "get" versus a post
which is not what the sample recommended. And once again, this was
working fine on the dev server. Why is production different?
