[appengine-java] custom vs. generated keys / storage?
Hi, I'm generating my own entity keys, with new Entity(Foo, myId). I noticed that in the DataStore viewer, these entities still seem to have a default key: Decoded entity key: Foo: name=myId Entity key: ahFzY2FyYWJyZWNvbW1lbmRlcnJACxIVUHJvZHVjdFJlY29tbWVuZGF0aW9uIiU1OTg1MEMzMzMwOUZGRjV8MjAxMDAxMDQwMTAzNTN8cHJvZF8wDA So the Entity key here still seems to be generated by GAE. Why is this needed? I do have a primary key already. So does it get stored as simply another indexed column? Does this impact storage space too? I don't need the GAE entity key at all, and would prefer not having to pay for its storage either :) Thanks, Viktor -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: any plans for deferred.defer in Java?
John, I think my earlier serialization error problems in production were because I was unnwittingly using an old version of GAE (1.2.6). Vince was never able to reproduce the issue in production.

For me, deserialization always fails on the dev server and always works in production. What I'm seeing on the dev server is that the bytes retrieved from the task payload (req.getInputStream) are not the same bytes that are sent; the result is the StreamCorruptedException. Again, though, I only see this on the dev server and never in production. Can you send me an example that fails in production? I'd like to understand what's going on before applying the Base64 encoder workaround. I'm not at all familiar with Guice, but I think I understand what you're trying to do. One thought I've had is that we could pass the HttpServletRequest object to the doTask() method. This would allow you to add attributes (objects) to the HttpServletRequest within your Guice filter and then retrieve them within your doTask() method. Vince On Fri, Nov 27, 2009 at 7:53 PM, David Chandler turboman...@gmail.com wrote: I've solved the serialization problems by Base64 encoding the serialized task before calling payload() and decoding it in the deserialize(HttpServletRequest) method. I'm guessing something in the task queue chain (either task queue payload storage or the servlet call when task is run) has problems transmitting the binary data, as the exception I was getting at one point was a java.io.StreamCorruptedException. I'll send another patch to Vince. My solution works, but I'm not completely satisfied that I've diagnosed the problem correctly. I used Apache commons-codec for Base64. Is it safe to use com.sun.misc instead? I see it in appengine.repackaged chain, as well, but don't see it as part of an official Google API. Somewhat related, I've wired up the Deferred servlet through the GuiceFilter so I can pass a Guice injector to Deferrable tasks. Since the task objects are not created through Guice, but rather by deserializing, I modified doTask() to accept an additional Injector argument. We probably don't want that in the official version of Deferrable, though. Is there a better way for my Deferrable classes to get access to a Guice context? I'm trying to avoid Guice.createInjector(), as it results in a duplicate PersistenceManagerFactory being created since other servlets are also being served through Guice.

The error I'm getting on AppEngine is invalid type code: 00 in Deferred.deserialize method. I've tried Base64 encoding after serialization in case it's related to special binary escape sequences that happen to be in the serialized object stream but still no success. I'm pretty sure AppEngine has written some custom code to do serialization because I previously got an AppEngine acess control exception when calling enableResolveObject(true) in a subclass of ObjectInputStream,

I'm sorry for being not able to explain adequately.
I tried.
cfm?fuseaction=Reports.SetReport
^
I think that this sign is a cause in the development
where the Exception occurs.
However, even if this sign is included
I do not think that production garish excetion is generated.
The appearance is seen for a while.
If there is no workaround
There might be a necessity for doing post to the Issue list.
thanks.

hey thanks, you seem to be right.
It seems a bug in the sdk, in production the problem goes away.
I am not sure what you mean though when you say, when value of the url
paramater dot is included.
Thanks again,

Hi,
I tried a little.
( SDK 1.3.0)
The condition that IOException is generated

This is not generated in production.
I think that the possibility of bug of development environment(SDK).
thanks.
I have an url which is redirecting:
http://www.accessdata.fda.gov/Scripts/cder/DrugsatFDA/index.cfm?fusea...
Reports.SetReportrptname=1reportSelectDate=12%2F2009ta=Submits
org.apache.http.client.HttpClient can follow the redirect without any
problem and get the content.
However URLFetchService has problems following the redirects,
java.io.IOException: Could not fetch URL.
Clearly the implementations are different, but I wonder how I can get
the URLFetchService to also read in that url. Could this be a bug? If
I ask HttpClient not to follow the redirect, it comes back with
temporarily moved, which I believe is HTTP Error 302.
Any help would be very kind.
The code using the URLFetchService:
URL url = new URL(urlStr);
URLFetchService urlFetchService =
URLFetchServiceFactory.getURLFetchService();
HTTPRequest httpRequest = new HTTPRequest(url,
HTTPMethod.GET,followRedirects());
HTTPResponse response = urlFetchService.fetch(httpRequest);
The code using HTTPClient
String url = http://www.accessdata.fda.gov/Scripts/cder/DrugsatFDA/
index.cfm?
fuseaction=Reports.SetReportrptname=1reportSelectDate=12%2F2009ta=Submits
;
HttpClient httpclient = new DefaultHttpClient
();
httpclient.getParams().setBooleanParameter
(
http.protocol.handle-redirects,
true);
HttpGet httpGet = new HttpGet
(url);
ResponseHandlerString responseHandler = new BasicResponseHandler
();
String
responseBody;
try
{
responseBody = httpclient.execute(httpGet,
responseHandler);
System.out.println
(responseBody);
} catch (ClientProtocolException e)
{
e.printStackTrace
();
} catch (IOException e)
{
e.printStackTrace
();
}

[appengine-java] Re: db error on 2010: Persistent class Class guestbook.Greeting does not seem to have been enhanced.
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. I know it sounds strange (you effectively are not doing anything to the actual file in the end), but it works.

[appengine-java] Re: why my app on GAE first access is so slow
There are some proposed new features for GAE to allow apps to keep their byte-code 'warm', either on the application server, or as a pre- initialized image on disk that can be loaded and not incur a full initialization. Check out this issue, contribute suggestions and vote for it if you want to see a feature like this; http://code.google.com/p/googleappengine/issues/detail?id=2456 On Nov 7 2009, 3:22 am, Prashant antsh...@gmail.com wrote: yes, your guess is right. if your app is inactive then app engine will remove your app servlets from memory and reloads from datastore (or wherever it is stored) when you access it first time. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
