Re: [appengine-java] Re: Backends.xml ERROR when deploying
Don, Thanks for helping us out getting backends running. I tried the targetbackendname/target parameter and it seems to work intermittently. I tried running the urls that would be run in the task queues and get a 503 error (below) every time. Is this something that can happen when the backend is busy?

[appengine-java] Java instances memory usage
Hi everybody, I would like to know how much memory space do your Java instances use. Mines use from 75 to 90 MB of memory on average basis.

You can add the remote_api Service into your java project.

Re: [appengine-java] Simple Google App Engine Datastore operation taking too long: causing DeadlineExceededException/DatastoreTimeoutException
Quick update: The query interface works. I was able to run the query across all the entities and start iterating over them (so it must lazy load when iterating). However I could not do a size() on the collection returned, so there must be too many items in the collection now. I can work around the now redundant relationship of account.getOrders() by querying. Now to figure out the best way to add a child object without accessing the parent's collection of children. Maybe I should switch to JDO+MySQL before I get in too deep - is this a completely wrong application of GAE? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Simple Google App Engine Datastore operation taking too long: causing DeadlineExceededException/DatastoreTimeoutException
Thanks for the reply. That's fair enough I can see why getOrders() in the add() method can be problematic. I actually thought it lazy loaded the collection under the covers, such that calling get() wouldn't actually fetch everything - looks like I was wrong about that. So I need to figure out how to refactor the add() code to add the order to the collection some other way. Any tips on that? Do I have to create my own Key that includes the parent Key? I still have the problem that as of right now I can not actually call account.getOrders() - for any reason, adding to it, or simply reading from it. It just freezes up, burns a bunch of CPU and then times out. Seems a bit of a waste even having the child relationship mapped. I'm just testing a Query approach right now, which I imagine is the query that would be running under the covers to access the orders of an account: Query query = pm.newQuery(Order.class); query.setFilter(account == accountKey); query.declareParameters(Key.class.getName() + accountKey); query.setOrdering(orderDate desc); I'll report back what I find out. Hopefully it allows me to get the accounts orders - if nothing else at least I can cursor through them with a query. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] DeadlineExceededException on Jetty session loading
Hey Googlers, Do you know why we get these DeadlineExceededException when Jetty's trying to load session data from the datastore ?

No, I don't think so. This issue never occurred for me. I also spoke to my customer about the gmail logout. He said he has not logged out.

[appengine-java] Disappearance of Entities
In the last two weeks I have seem to have lost 60 entities. The weird thing was that those entities were children of other entities which exists in the Data-Store. I determine they were lost due to the fact that there isn't any application logic that can delete them and they are tightly coupled to their parents in a transaction manner. I am concerned. My application is a production one, and I am paying for 3 instances only to make sure that data reliability/consistency will be part of the features I get. My application is not mission critical, and the traffic is rather low, so should I encounter issues like data reliability? I recently read about the high replication option, should I migrate my data to there? will it be more reliable? In addition I am making backups on a weekly basis, is there ability to view the backed up data?

[appengine-java] Re: SpringMVC RESTful + JSP + GAE/J .. 404 not found on JSPs..
Quick question, do you have error.jsp in your /WEB-INF/view/jsp/
folder? Also, in your first method
(TestController.testStringResult()) you misspelled redirect, which
will also result in 404. Also, take off the leading / for the
testModelAndView() and testString()...you're effectively looking for /
WEB-INF/view/jsp//error.jsp (which should still resolve, but is not
necessary and clouds up the code a bit)

Re: [appengine-java] Re: JSP page as Warmup Servlet
JSPs are compiled into servlet class files during deployment, not in each instance. Warmup requests are GET requests, so doGet() will be called. We recommend that you override service() instead, as the default implementation of doGet() calls it, but you can do either. And yes, warmup servlets can have admin auth-constraints, which will be bypassed automatically for legitimate warmup requests.

I use JDO but I don't use the built in relationship handling. I manage my own relationships and use JDO just for the property/entity mapping part of it. It seems to make life a lot simpler when trying to get around these types of situations. If you can make the Orders not be children of the Account class and manage your own relationships that will make your life a lot easier in the long run even if it's more work initially and your code much faster and efficient, IMHO.

Re: [appengine-java] Re: Getting class cast exception in BackendServersFilter after 1.5 sdk update
I understand what's going on now. No need to send me more war files, but my thanks to Nischal for a great test case. Struts2 wraps the request with StrutsRequestWrapper, and apparently modifies getAttribute() calls to check XWork's ValueStack if there is no attribute with the specified name. XWork uses OGNL, and OGNL is trying to interpret the attribute name as an expression. We have some internal headers (e.g. X-AppEngine-BackendName) that we are also using as request attributes in some cases. As far as I can tell, this is allowed by the servlet spec. However, OGNL is interpreting the minus signs as subtraction and the unknown strings as 0 and returning a BigDecimal. Weird. Since XWork is returning a non-null value for one of our backend-related attributes we think this is a request that should be redirect to a backend, so we're going through some new code in 1.5 that isn't relevant in your application. However, we later fail because the attributes were of the wrong type. I will get this fixed in the next release, but I've been unable to find an easy workaround for you folks. There appears to be no way to disable the use of OGNL in Struts2. My best guess is that you can use the struts.valueStackFactory constant to register a custom ValueStackFactory that either does not use OGNL, or short-circuits this particular case.

Re: [appengine-java] DeadlineExceededException on Jetty session loading

It looks like a bug as there is only Google App Engine code being executed here (see stacktrace below). Any given entity in the datastore may be unavailable periodically, so this doesn't necessarily indicate a bug unless it occurs frequently. However, the High Replication datastore is far less sensitive to unavailability in any given data center so I would strongly recommend that you switch to it if you're sensitive to datastore latency outliers. And (still haven't got an answer about that) why does it have to kill and restart the instance when such exceptions occurs ? Doesn't seem to be optimal in threadsafe mode. Yes, it is sub-optimal, but as we are currently using Thread.stop() it is really unsafe to continue using the same Java VM for subsequent requests. We're considering having an additional deadline mechanism, perhaps based on Thread.interrupt(), which you could opt into that would let us avoid this.

And why we have to wait 30s to know that these entities are unavailable ? What is really annoying is that when an instance is restarted all pending requests/threads are also stopped which results in a lot of additionnal errors. And when you had only one instance running, all further requests throw 500 errors while we are waiting for a new instance to be started.

Because the datastore is a network of servers separate from your backend process, we still charge for the CPU usage that your API calls incur on those servers.

[appengine-java] Change where Deploy is built
It seems that whenever I deploy, the build files are all being saved to my local settigns/Temp folder. Is there a way to change where these files are saved? My C folder is very full and building to this folder takes a long time. I think I could deploy much faster if these files were written to the same folder the project is saved in or at least the same drive. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Vik,
Post your code where you're creating the ByteArrayOutputStream and
creating the PDF with it. It'll be more helpful then what you've
posted. I'm a little concerned you still don't have this part correct
since you're still using out as a variable name. You're code should
be similar to:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
/* this part is from your previous email. I don't use PDFJet so I
can't validate this code for you */
PDF pdf = new PDF(baos);
some actual writing.
pdf.flush();
/* taken from docs */
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
String msgBody = ...;

Try not adding the image or the font. Just try to get as simple a PDF
working as possible.
