FEATURED COMPONENTS
First time here? Check out the FAQ!
I am going through lot of frustration with ZK and Google App Engine (GAE). First thing Zk's startup it takes too much time to start and with GAE's concept of inactivate/activate the server depends on load I get 500 server error every time. I do get many many logs in the error log where it says request is taking too long time. The time to process request is significantly long with ZK's architecture of serving scripts and wpd files from jar file. I can't put them in Google's CDN to better manage them.
Second issue is session data. Zk's extensive use of session is not working properly with GAE. I get "too many web pages opened errror" very frequently. I just have a list box which displays a paginated view over 300 items and I get the above error. I am not sure how the data is managed with list model. I guess ZK keeps all the data in session and GAE tries to keep the session either in memcache or datastore which is causing serious issues in terms of limits etc...
Any one is using ZK on GAE successfully?
There is a sample application that you can check it out with svn:
svn co https://zkforge.svn.sourceforge.net/svnroot/zkforge/trunk/zk-gae/ zk-gae
Hi kesavkolla, can you post your code
