[appengine-java] channel api check user connected
when using channel api, we need to keep track of all users so that we can loop through the list and send broadcast message to all. how to know whether user still connected without require user to frequently send ping back to server that they are still opening browser? what technique do you,guru use to minimum flooding the bandwidth? 1. can hannelService.sendMessage(CHANNEL,) able to get error message if user channel already closed? (user closed browser without log out) 2. can hannelService.sendMessage(CHANNEL,) give status where client guaranteed success receive the message? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] user authentication when moving off app-engine
I have a client I've developed an app-engine app for, but for reasons to silly to mention here, they'd like to move to a hosted server model. I've developed my own implementation of all the Google services my code relies on (like Memcache and TaskQueue etc.) however, I'm having a bit of a hard time with the UserService implementation. In particular, it seems I need to use the OpenID protocol to keep on allowing users to login to the system with their GMail accounts. The documentation for Googles OpenID implementation indicate that the userId is dependent on the relying parties credentials (which totally makes sense), this would mean that when our application is hosted off the App-Engine, we're going to get different userId values for users that have already authenticated to our system. This makes data migration a bit touchy. The App-Engine docs seemed to indicate that the supplied userId was the same for all apps requesting user authentication. Is there a way I can use the same mechanism for user login when my app is running on a different server? My main concern revolves around the fact that we use the Google supplied userId as a unique identifier for users rather than their email address, since the App-Engine documentation indicated that users can change their email address, and the only "stable" identifier was the userId. Has anyone migrated off the App-Engine (for whatever reason) and been able to maintain the user authentication? If not, does anyone at Google have any suggestions as to how to migrate the data such that I can recognize return users and load their historical data?

[appengine-java] VerifyError using Joda Time on GAE
Is anyone else having trouble with Joda time on appengine?
I just added it to my app, and attempts to use it generate a
VerifyError like this:
java.lang.VerifyError: (class: org/joda/time/tz/ZoneInfoProvider,
method: loadZoneData signature:
(Ljava/lang/String;)Lorg/joda/time/DateTimeZone;) Accessing value from
uninitialized register 8
at org.joda.time.DateTimeZone.getDefaultProvider(DateTimeZone.java:454)
at org.joda.time.DateTimeZone.setProvider0(DateTimeZone.java:408)
at org.joda.time.DateTimeZone.(DateTimeZone.java:113)
at com.similarity.queen.JodaTestServlet.service(JodaTestServlet.java:30)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
at
org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:511)
This was generated by a simple servlet method that looks like this:
protected void service(HttpServletRequest req, HttpServletResponse
res) throws ServletException, IOException
{
DateTimeZone dtz = DateTimeZone.getDefault();
log.info("#" + dtz.toString());
}
The strange thing is that when I create a from-scratch appengine
project, joda time works. I'm not doing anything special with
classloaders, and I don't have time to rip apart my project to figure
out what is somehow interfering. I can only suspect it has something
to do with the repackaged version in the SDK, but I can't tell - I'm
using the correct org.joda.* imports.
I'm about to try recompiling Joda from scratch myself, but does anyone
have any idea what could be wrong?
Thanks,
Jeff

[appengine-java] Re: URLFetchService
My guess is that the JSESSIONID (or whichever session cookie used by the
service) that is received in the HTTPResponse of your first fetch() is not
sent back with your second fetch. As a consequence, the service does not
know you're logged in. Here is how I would solve it (I did not test that
code):
// ...
HTTPResponse response = urlFetchService.fetch(httpRequest);
List headers = response.getHeaders();
String cookies;
for (HTTPHeader header : headers)
if ("Set-Cookie".equals(header.getName())
cookies = header.getValue();
httpRequest = new HTTPRequest(url,HTTPMethod.POST, validateCertificate());
if (cookies != null)
httpRequest.setHeader(new HTTPHeader("Cookie", cookies));
// ...
You may run into the following issues, though:

[appengine-java] Import test data to local datastore
I'm aware that this issue has been brought up before, but I've not been able to get any resolution on it. Wondering if anyone has any advice that my google-foo is not finding. I would like to import some test data to the local datastore of my Java application. This would allow me to test bug fixes locally before deploying them, and speed up my development process significantly. I was able to download some data into a .csv file from my app using the python-based bulk loader (instructions here: http://ikaisays.com/2010/06/10/using-the-bulkloader-with-java-app-engine/). Now I am trying to push the data to my local app, and not having any success. The command I'm running is as follows: python2.5 appcfg.py upload_data --application= --kind= --filename=data.csv --config_file=config.yaml --url=http://localhost:/remote_api/ This prompts me for a username and password. Various sites have said that I should be able to enter any random username, and a blank password. However, after I do that, I get the following stack trace: File "/usr/lib/python2.5/urllib2.py", line 387, in open response = meth(req, response) File "/usr/lib/python2.5/urllib2.py", line 498, in http_response 'http', request, response, code, msg, hdrs) File "/usr/lib/python2.5/urllib2.py", line 425, in error return self._call_chain(*args) File "/usr/lib/python2.5/urllib2.py", line 360, in _call_chain result = func(*args) File "/usr/lib/python2.5/urllib2.py", line 506, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) HTTPError: HTTP Error 404: Not Found [INFO] Authentication Failed At the console, it prints [WARN] No file found for: /remote_api/ But I have the remote api servlet enabled at that url in web.xml, and have been able to use it in my production app. Is bulk uploading like this to a local datastore even possible? The documentation on the bulkloader says that it's impossible to download data from a local app, but is silent about uploading. Is there another way of doing this besides the bulk loader? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] URLFetchService
Hi:
What I am trying to do is use the google app eng URL fetcher service to
access a HTTPS url but before I can arrive to the page I need I first have
to post login details to the site and then I want to navigate to the page
where my data is.
Basically I need to authenticate to the site using my login details and then
I want to retrieve another page from the same site which I only access after
I have logged in. How can I do this using URL fetcher service ?
This is the code i am using for the moment.
URL url = *new* URL("MY_HTTPS_URL");
URLFetchService urlFetchService= URLFetchServiceFactory.*getURLFetchService*();
HTTPRequest httpRequest = *new* HTTPRequest(url,HTTPMethod.*POST*, *
validateCertificate*());
httpRequest.setPayload("login=mylogin&password=mypassword&action=login"
.getBytes());
HTTPResponse response = urlFetchService.fetch(httpRequest);
httpRequest = *new* HTTPRequest(url,HTTPMethod.*POST*,
*validateCertificate*());
httpRequest.setPayload("action=summary".getBytes());
response = urlFetchService.fetch(httpRequest);
Any help appreciated.
Thank you.

Re: [appengine-java] Re: How to POST to the BlobStore from a command line Java program?
Hi, what Didier's right! also you could use webservices REST-type, and write your own handlers with this new way, you could perform the specific operations like: @POST - insert @PUT- update @GET - select @DELETE - delete. so that, you can see that you've got all the basic operations like in a DB, and acording to what Didier said, you could write a POJO to store all your data. Then, in the client side, you could write a program to perform all the tasks for maintaining these POJOs ( select, update, insert, delete ) programaticly. here you can find a very helpful project about REST-type services. http://www.restlet.org/ hope this was helpful. cheers, On Wed, Feb 23, 2011 at 11:11 PM, Didier Durand wrote: > Hi guys, > > I don't have a direct answer to your question but I have another > proposal: > > why don't replace the blobstore by a pojo containing a list of gae > blob objects.

[appengine-java] Re: ClassNotFoundException
Another random guess - have you specified a serialVersionUID on your serializable classes at all?

Re: [appengine-java] Re: Protocol Buffer in Google app engine
If you need to transfer datastore data as POJO-s to a java client you can use Hessian. I have tried it and I know that it works (I used Android as a client). You can find more info here: http://monkeyboy-code.blogspot.com/2010/07/using-gae-as-backend-for-android.html and here: http://monkeyboy-code.blogspot.com/2010/07/using-hessian-in-your-android.html -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
