Hi Karthik, the application which I uploaded is, the sample application that comes along with the appengine-java-sdk-1.4.2. I did not make any modifications.
Since, I've just started learning Google App Engine, I tested by deploying any existing application under my domain and thats it. FYI, I followed the following Getting started tutorial, *http://code.google.com/appengine/docs/java/gettingstarted/installing.html*<http://code.google.com/appengine/docs/java/gettingstarted/installing.html> Also, I attach the Greeting.java class for your reference. And, if your have appengine-java-sdk-1.4.2, can u just try uploading the appengine-java-sdk-1.4.2\demos\guestbook application to google app engine and let me know. Thanks, Nagaraj. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
