[appengine-java] java.io.IOException: unexpected response from remote api when using Remote API to connect to local dev server
Hi everyone,
I am trying to use the Remote API as described in [1] to connect to
the local data store. But when I call the RemoteApiInstaller's
install() method I always get the mentioned exception. Here is the
complete trace:
Exception in thread main java.io.IOException: unexpected response

Anybody else having this problem? Or better yet: a solution? :)

[appengine-java] Deploying two apps to one datastore memcache
I currently have an app which has two distinct parts. One is a public facing part which relies on basic servlets and very few dependencies - it is dynamic and uses the datastore and memcache extensively but I need this part to scale quickly and efficiently with as low a cost as possible. The second part is essentially an administration interface, it's much heavier, makes use of Guice, Cambridge templates, Objectify and I'm just about to add a fairly heavy library. I can make the first part load on app engine in just over a second, but once I add in the extra features needed for the second part, start- up takes over 10 seconds. This is probably fine, but I'd like to serve people quicker than that, and I might get lots of traffic very suddenly which could cause lots of new instances to start at once. So, is it possible to separate these but have them access the same datastore and memcache? Can I use different versions of the app for this? Is that the only way? Will different versions load separately in a way that will work correctly for scaling? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Deploying two apps to one datastore memcache
How about deploy as two versions? So that different versions of instance are loaded independently. With regards to admin console, you might be interested at Yaachttp://code.google.com/p/yaac/. So that you don't have to develop some general admin functions in your version again. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Conversion API: Best way to track down conversion issues?
Hi, I'm getting started with the new Conversion API. While it works like a charm for some documents (html-pdf) I end up with empty pdf's for others. The pdf's seem to be generated with Prince (princexml.com), so I've downloaded the latest release to track down the issue. Prince converts the documents just fine, so I'm wondering which version is used on GAE? Or is there another way to get more debug info?

[appengine-java] Error forcing a logout and redirect
I'm trying to force a logout and redirect by using this code from a jsp page: pageContext.forward(userService.createLogoutURL(../pageName.jsp)); This works in the dev environment, but not on the GAE servers. There I get this error: Error: NOT_FOUND I get the same error if I change ../pageName.jsp to pageName.jsp.

[appengine-java] Re: datastore.delete() not deleting objects and not generating exceptions
Have you tried surrounding the select and delete queries in once transaction? See: http://code.google.com/appengine/docs/java/datastore/transactions.html There is no reason it shouldn't work otherwise, but it may be worth a shot. Also, with it being the same 213 objects, maybe those particular objects are corrupt. Have you tried to manually delete them from the admin console? On Dec 8, 6:22 pm, Michael michael.ol...@gmail.com wrote: I have an hourly cron job that deletes data from the datastore older than one month (this data is archived elsewhere for long term storage). The first run of that cron job on Tuesday after the datastore came back up behaved quite unusually, ended with java.lang.OutOfMemoryError: Java heap space, and hasn't completed once since then. While it is possible that this is pure coincidence, I'm wondering if something done during the maintenance resulted in this behavior. I have been unable to get this cron job to run correctly since then. The job is quite simple, and has been running happily for about a year; I will present the idea here for brevity and attach the source for those interested. In essence the job does the following: - retrieve at most 500 entities older than 1 month by their keys only - send all resulting keys as a list to datastore.delete() - repeat until no results are returned The first run after maintenance produced the attached log-excerpt.txt. The brief version is the following: - deleted 500 objects - deleted 465 objects - deleted 213 objects (repeated 395 times) - out of memory It seems that, after actually deleting the first 752 objects of the query, the datastore got stuck on the next 213. The same 213 objects were sent repeatedly to datastore.delete(). No exceptions were generated, but the data was obviously not deleted. The next attempt (the job was retried since it crashed) produced almost identical output. This time, it actually deleted 174 objects, then tried to delete the same 213 objects over and over until it, too, crashed with an OutOfMemoryError. The run after that actually deleted 8 objects before it crashed in the same manner. This continued until the error ran my application out of quota for the day, at which point I got a notification email and went to go pause the queue that these jobs run under. Note, I am not on the high replication datastore. I do not know why this is happening, but it is currently an insurmountable obstacle. I tried unpausing the queue temporarily and running the problematic job, and this time I did not even get the previously frustrating but informative output; instead, I merely got the A serious problem was encountered . . . message on both runs. Any help in getting this fixed or understanding the problem would be greatly appreciated. log-excerpt.txt 60KViewDownload DeleteOldDataServer.java 4KViewDownload -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Securing cron urls / task urls using UserService and not using web.xml
There is probably a better way, but you could look at the user agent
string (I see in my logs that the user agent string for pages launched
by cron look like AppEngine-Google; (+http://code.google.com/
appengine).
Also, cron jobs are executed as admin. You may be able to use the
userService.isUserAdmin() functionality, although I haven't tested
that.

Hi,
I am currently trying to secure my urls that are accessed by cron jobs /
tasks.
Normally I would use web.xml like that:
security-constraint
web-resource-collection
web-resource-nameProtected Area/web-resource-name
url-pattern/cron/*/url-pattern
/web-resource-collection
auth-constraint
role-nameadmin/role-name
/auth-constraint
/security-constraint
However, I got a constraint, where these urls should be allowed to be
triggered by other authentification mechanisms.
Therefore I tried to use the UserService if a authenticated user is
hitting the url. I though cron is an authenticated user...
UserService userService = UserServiceFactory.getUserService();
if (!userService.isUserLoggedIn()) {
//do nothing
} else if (!userService.isUserAdmin()) {
//do nothing
}
//allow stuff to work...
}
But I do not get a logged in user when cron is programmatically hitting my
urls.
Is there a way to determine if google app engine is hitting my urls
without using web.xml security constraints?

Re: [appengine-java] Re: Securing cron urls / task urls using UserService and not using web.xml
Raphael, is is the isUserLoggedIn() that returns false or the isUserAdmin()?
If the first returns false but the second returns true (which would make
SOME sense I guess!) then you could refactor your code to only run if
isUserAdmin() is true, rather than them both having to be true.
I have no idea, just a guess I'm afraid.

[appengine-java] Re: Securing cron urls / task urls using UserService and not using web.xml
The user service will always return null when cron is calling. The
way to tell that cron is calling is to check for the X-AppEngine-
Cron header. It is set by the cron service and is stripped from all
other calls to your URLs. That is the best you can do until the GAE
cron service is better integrated into the user service.
