[SOLVED] Is the war compression idempotent?

Hi to all, I want to deploy an application on google app engine (is openAM) but I have a WAR file of the app. You cannot deploy war files on GAE so I just decompressed the war and then tried to upload the directory. At this point the google uploader finds many errors in the application when it compiles jsp files, it seems a bit strange to me since it is supposed to be a stable release. That's why I was wondering if you can do a thing like that, is the war file just a compressed version of the project directory or it has something different?

Sorry for the long message.

A war file is just a zipped up version of the folder structure of the web app.

Thank you, really fast! So I am wondering why it doesn't succeeds, sometimes the error is for a file missing, sometimes for a wrong method call. Maybe when you upload a war the server isn't supposed to do all the checks that the GAE upoader does (for example check if all the jsp files can be compiled).

I deploy in Tomcat which performs no checks at all.

Yes but I have to use Google App Engine. Thanks anyway.
