Running GWT application in production mode

I am newbie to GWT. I have built gwt maven project. To run in development mode, I first compiled project Google|Compile Project, then from command mvn gwt:run, it runs fine on 

http://localhost:8888/index.html?gwt.codesvr=127.0.0.1:9997

but for production I want to access module

http://localhost:8888/index.html

When I omit gwt.codesvr= argument, I am getting error "gwt module may need to be recompiled". After Recompiling, I get the same error. Any help/pointer?

Thanks,

I have followed the steps mentioned in the link, but still getting the same error. Please help. - Mustansar Saeed
You might check to be sure that the module you're loading in your html file matches exactly the name of the module in your gwt.xml file. I was once in a situation where the shortname I had assigned to the module was respected in dev mode but not production - I'd forgotten to update it in some places, and dev mode was smart enough to figure it out, but production was not. - Riley Lark
I have not assigned short name to the module. gwt.xml file looks like <module><inherits name='com.monitorme.ui.Ui'/><entry-point class='com.monitorme.ui.UiStandalone' /><inherits name='com.google.gwt.user.User' /></module>, is this compilation issue or dependency issue which is not making required files? thanks - Mustansar Saeed
I'm using gwt since 2.0 now after upgrading from 2.6.0 to 2.7.0 I started to see this issue - montss

You did it correctly, but as the error states, the module needs to be re-compiled (GWT Compiled). Once recompiled, Force your browser to reload (Ctrl + F5). If that doesn't work, you can look at this answer I wrote regarding cleanup of compiled output. Do what's listed there, and try running GWT compile again.

To run production mode outside Eclipse, you must do a GWT compile and create a WAR file, which you can then deploy on a Java application server such as Tomcat. This process is much easier with an ant build script.

To make an ant build script for your project:

You can easily create an ant build script by running the webAppCreator command from the directory where the GWT library is installed. That command will create a sample project just like clicking "New Web Application Project" in Eclipse, except it will also make a build.xml file.

You can run it in Eclipse by right clicking build.xml > Run As... > Ant build. By default it will run the build target. It also has a war target, which you can run to create a WAR file.

For more details on the webAppCreator, look here.
