I m trying to create a GWT app- it has a single HTML file (main.html) and the java class is main.java.

In Eclipse, I did right click-> GWT -> Module and defined the new module correctly.

However after adding some code, when I try to run the app in Dev mode, I get the error 

"Could Not find any host pages in project <project-name> "

I have simply added some code to main.java, then saved it and tried to run the app in dev mode... What am I doing wrong here? Is there something I am missing here?

Normally it could happen if WAR Directory is not defined for this project.

So go to Project properties --> Google(Web Application),

  1. Check the checkbox whcih says "This project has a WAR directory"
  2. In WAR Directoy textbox, browse and give path to your project webapp something like "src/main/webapp"
  3. Check the Checkbox "Launch and Deploy from this directoy"

This should fix your problem.
