Question

We have a gwt app deployed on gae for java. The app runs fine in google chrome but fails with below exception on ie and firefox

NetworkError: 404 Not Found – http://www.sakshum.org/adminmodule/67883654A8944A4C561CF25763FB1D79.cache.html

based on Setup a GWT Project correctly with SVN and Eclipse we have excluded the files in adminmodule directory to upload to app engine.

Please advise what is reason for it to fail and how to make it working.

The ignored patterns are:

.svn
*.bak
classes/
thumbs.db
*.class
.gwt*
gwt-unitCache/
deploy/
war/adminmodule/
war/sakshumwebgae/
sakshumweb/war/WEB-INF/deploy/adminmodule/
sakshumweb/war/sakshumwebgae/
.bin
*.orig

You will get 404. HORROR!!!!

Currently only /deploy/ folder can be ignored and not war/gwtmodule.

All the gwt generated scripts are in war/gwtmodule and you need to upload them per compilation into appengine.

These are generated every build in compilation phase and hence are not checked into svn.

They need to be in deployment folder for APP Engine.

I suggest you go through the GWT teams excellent document for App Engine with GWT https://developers.google.com/web-toolkit/doc/latest/tutorial/appengine

Edit –
<modulename>.nocache.js loads <longnumeric>.cache.html based on browser * language permutation. GWT compiles your java code to create the <modulename>.nocache.js and the relevant cache.html files. cache and nocache indicates whether browser is supposed to cache or not cache the file.

You will have the .nocache.js script reference in your html file for the gwtapp.
