on our gae for java app using gwt on loading the app and checking in firebug i see error http://www.sakshum.org/sakshumwebgae/8CB611AC7A0B5B6BE2C4C99A8EA4DEFE.cache.html as a result gwt modules seems to be not getting loaded.
I am assuming this file should be auto generated by gae. so why i m facing it and what can be done to solve it?
Your asumption is wrong. That file is generated by the GWT compilation (at the same time the
sakshumwebgae/sakshumwebgae.nocache.jsis generated) and should be deployed within your app.
