I am attempting to get familiar using the java calendar api (v3r7) on GAE
(oauth-1.8-beta) with GWT.
I am running an updated calendar sample originally provided by Yaniv Inbar.
I believe I am logged in but I get the attached error when I am trying to
authorize in order to initially load my calendars. BTW - The StockWatcher
samples with RPC and JDO store I previously tried worked great.
Any help or a pointer to an updated CalendarAPI sample would be very
appreciated!!!
*Here is the error in the GAE server log ...*
javax.servlet.ServletContext log: Exception while dispatching incoming RPC
