[google-appengine] Re: NoClassDefFoundError (org.eclipse.core.runtime.Platform)
Hey Patrice, I actually posted this http://stackoverflow.com/questions/28984276/noclassdeffounderror-on-appengine-with-org-eclipse-core-runtime-platform on StackOverflow yesterday. Nothing helpful yet though. Will now report on the public issue tracker as you suggested. Thank you!

[google-appengine] Re: Loading up data in the init() method
Hi Vinny, Sorry for the late response. I followed some suggestions of yours and have now decided to rather initialize the dataset as a cronjob since that allows more time for a job to be completed. Plus the dataset needs to be continuously updated from the source URL so I could schedule the cron for every X minutes or so. Thanks!

[google-appengine] java.lang.NoClassDefFoundError after deployment to GAE
Hi,
I have a web app that uses a cron job in the beginning to fetch data from a
URL, works on it and serves to external clients. The project runs perfectly
on the local machine without a single error but as soon as you deploy, the
cron results in the following:
Uncaught exception from servlet java.lang.NoClassDefFoundError: Could not
initialize class org.eclipse.core.runtime.Platform
There is only one external jar that I use in my project:
*org.eclipselabs.emfjson_0.4.1.201207260839.jar*. Reason being that it is
no more available on the public Maven repository. My POM looks like:
dependency
groupIdorg.eclipselabs/groupId
artifactIdemfjson/artifactId
version0.4.1/version
scopesystem/scope
systemPath
${project.build.directory}/war/WEB-INF/lib/org.eclipselabs.emfjson_0.4.1.201207260839.jar
/systemPath
/dependency
All that I can imagine the error is somehow related to the fact that an
external jar is being included in the project and when deployed, the server
cannot find it. What can I do to get rid of this error? I've exhausted my
Google search.

[google-appengine] Loading up data in the init() method
Hi, I have a RESTful service that gets XML data from an external URL, does some work on it and serves it to its clients.

This works on the local machine properly, but not when deployed to GAE.

[google-appengine] Re: Loading up data in the init() method
Thanks for your response Vinny! 1. I made a deliberate call to *_ah/warmup* which gives: GET /_ah/warmup HTTP/1.1 200 0 2. To *_ah/startup* which gives GET /_ah/startup HTTP/1.1 404 204 This is my first GAE project and I'm not a paid user yet so upgrading isn't currently an option nor increasing idle instances since not even a single instance is up yet. Cron isn't an option currently since the dataset has to be there to fulfill even the first request that comes in (but it can be later used when, let's say, I have to update the dataset regularly from the source). I don't think that the warmup request solution may work for me because it says here https://cloud.google.com/appengine/articles/deadlineexceedederrorsthat: *Currently, the deadline for requests to frontend instances is 60 seconds. (Backend instances have no corresponding limit.) Every request, including warmup (request to /_ah/warmup) and loading requests (loading_request=1 log header), is subject to this restriction. *Also see GAE issue reported here https://code.google.com/p/googleappengine/issues/detail?id=7836. Do you have some suggestions? I'd be really glad to hear from you!
