Re: [google-appengine] Re: Reverse Proxy for custom domain SSL and Users Service possible?
I think I'd have the same issue since the continue url would be relative to appspot unless I specify it fully, but that results in a 500 =(. However, if someone got it to work please let me know!

[google-appengine] Getting server 500 error on just deploying sample code !!!

[google-appengine] Integeration of ZK with Google App Engine
Hi, I tried the demo of the ZK direct RIA framework as I had read that it is compatible with Google App Engine. I downloaded the latest version and then was trying to create my first project using the How- To wiki: http://books.zkoss.org/wiki/ZK_Installation_Guide/Setting_up_Servers/Google_App_Engine but it the link explains how to configure the ZK project but doesn't tell how to create a Google App Engine project that has ZK support. I tried to manually do that but didn't really work. Can somebody please tell me how to make a GAE project with that support.

[google-appengine] Re: Pagination using Query Cursors
Hi, I have not yet found the appropriate solution to this problem. The idea of iterating and caching the cursor values at every start of the page is one solution that I had also tried. It works, but I guess it is not the optimum way to do it. There should be a better way which has no performance issues.

[google-appengine] Pagination using Query Cursors
Hi, I have been trying to perform Pagination on the App Engine using Java, for a large data set of information. I read about it on many previous posts including the official documentation of Google App Engine : http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html#Query_Cursors Considering the constraints of fetching data from the datastore, nearly all the posts suggested the use of Cursors (a feature that was added in version 1.3.3.1 of the App Engine SDK ). Most of the code examples that I came across were performing pagination by displaying the pages sequentially, but my requirement is to even allow displaying the result for any page, i.e a random access is required. In simple words, I wish to attain a pagination which is similar to Google's way of displaying search results. After going through the Java Docs of the SDK, I got to know that Cursors can only store the index value for the next set of entries. Is there any other way to satisfy my requirement? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
