Testing GWT + GAE locally (not DevMode)

[xybrek]

`DevMode` works just fine when testing a GWT + GAE application. However the problem arises when we try to deploy our app in GAE cloud, and suddenly we get:

    GWT module 'app' need to be recompiled

After a long update/upload time. The issue now is how can we test locally and be sure at least that we won't suddenly get this error. In a typical GWT (non-GAE) its very easy to do, just deploy it to a local Tomcat of JBoss AS server. 

However we can't do this for a GAE app. So what are the options to achieve this?

 - Where to deploy a GWT+GAE app to be able to see if the GWT needs to be recompiled or what, before we even try to upload it.

 - Or are there any better way? `SuperDevMode` perhaps?

When deploying does the GWT module compile before it deploys? It should compile before it deploys. Another option to verify its compiling is delete the gwt project module and related from the war directory, thats compiled, before deploying. (Don't delete any static resources.) Is the compile comping the module getting deployed, or is there more than one module and one module is not getting compiled. There are a few other reasons that this happens, but maybe that hints at helping deployments.

Hmmm... that could be the problem, when deploying I use the appcfg.cmd update "path/to/war" 

Do you mean I need to upload/update through the maven plugin? I just use maven for local deployment: like "mvn gwt:run"

Will this command mvn gae:deploy deploy to GAE as well as compile GWT? I'm thinking that this is analogous to mvn gae:run that does not involved the GWT side of things?

Issue resolved by following this blog article: 

http://bpossolo.blogspot.com/2013/01/the-ultimate-guide-to-gwt-gae-maven.html

and the maven command allowed the app to deploy (with GWT) to GAE cloud: appengine:update

FWIW, we nearly always deploy to a sandbox appid and test before deploying to production.

Hi Jeff, how's it going with Motomapia? Anyway, yah, that should be the case, however, the App i'm trying to push is just a test app, since i'm not finished with the app... I just needed to check how it will look like and behave in the GAE runtime. Where when I found something that the SDK runtime was able to miss.  Cheers!
