[appengine-java] OVER_QUERY_LIMIT
I need to construct a distance matrix among some 100 locations (this is about 10K requested). In order to avoid the request quota issue I wrote a program that submit an http query every 40 seconds. That is less than 2500 queries a day My query look like this http://maps.googleapis.com/maps/api/directions/json? origin=+lat1+,+long1+destination=+lat2+,+long2+sensor=falseunits=metric (where str(lat) and str(lon) represent are strings contain the latitude and longitude, However after 100-200 queries I start getting the OVER_QUERY_LIMIT error. Moreover, even after waiting for several hours I can not submit more queries from the same IP. That is it seems that I was blacklisted PS. I know that this is not a Java API issue, but I saw that the issue is discussed here -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Using a Key in a query filter
Hi, I'm trying to use a Key inside a query filter. I am using this to enforce uniqueness on a field (GAE does not support unique constraint) . In my query I try to fetch from ser a user with same name as the entered one, but with different key (if I get no result - user name is not taken). This approach works like wonders in the development environment, but crashes and burns in the deployed environment. I get an exception: Nested in org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.jdo.JDOFatalUserException: Illegal argument NestedThrowables: java.lang.IllegalArgumentException: __key__ filter value must be a Key: javax.jdo.JDOFatalUserException: Illegal argument at org.datanucleus.jdo.NucleusJDOHelper.getJDOExceptionForNucleusException (NucleusJDOHelper.java:344) at org.datanucleus.jdo.JDOQuery.execute(JDOQuery.java:275)... again - this works in development environment. any suggestions? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Html to image in java
Hi, In my app I need to capture Html into image. All solutions, code, third party etc. require either windows platform, or Java AWT library, which is not supported by GAE. The ImagesService by Google, is designed to manipulate images once you have the source image.

[appengine-java] Re: Spring Security with GAE - Adding object into HttpServletRequest does not appear to be working
Hi,
I'm also trying to get Spring security to work on GAE.
regarding your problem:
1. there is an issue with Spring Security 2.0.5 on GAE, you can find a
fix here:
http://www.google-app-engine.com/blog/post/Spring-security-fix-for-google-app-engine.aspx
2. I couldn't entirely substantiate it, but I read of a lot of
problems deployed GAE has with AOP (as opposed to Google development
environment on eclipse). maybe this has something to do with it as
well.
hope this helps a bit.

Hi,
I've created a GAE web application using Spring 3.0 and Spring
Security 2.0.5.
After a little heartache and help from reading the posts on the forum,
I managed to get it all working locally, with users able to register,
validate their accounts via email and login in securely.
When a user logs in, I wanted to make their details available across
the site. I did this by creating an Interceptor, responsible for
pulling the prinicipal from the Spring Security Authentication class
(retrieved from the SecurityContextHolder) and then placing the object
in the HttpServletRequest object. Below is a snippet of code from the
interceptor.
public void postHandle(
HttpServletRequest request,
HttpServletResponse response,
Object handler,
ModelAndView modelAndView) {
try {
Member member = securityContext.getMember();
request.setAttribute(user, member);
log.info(injecting user into request);
} catch(SecurityRuntimeException e) {
// do nothing - will be thrown if no user is logged in
}
}
The user's information is wrapped in a 'Member' object, with the
securityContext responsible for retrieving it from the
SecurityContextHolder.
Locally, on the GAE development environment, everything works fine!
The interceptor correctly places the principal in the request and my
JSP's can readily access it. However, when I deploy the application to
the app engine, it does not appear to work. The logs have not provided
any clue as to why the request does not appear to have the principal
in it.
Is there any reason why the interceptor would not work on the app
engine? Or, is it ill-advised to add objects into the
HttpServletRequest?
I'm tearing my hair out with why it's not working, and it's the only
thing within my application that isn't! So any help or advice offered
is much appreciated. I'm hoping to have my code up in the Google Code
repository so if anyone wants to have a look, they're more than
welcome.
Thanks!
Sully

[appengine-java] Re: updating object doesn't work anymore
Thanks for the quick response! I tried switching to getPersistenceManagerProxy() but didn't get any change. After experimenting some more I finally found my problem... my object of User had a list of Category, and I carelessly used @Transient (javax.persistence) instead of @NonPersistent (javax.jdo.annotations) when persisting my User, JDO damaged my Category table...
