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?
