Question

I’m trying to create a GWT app that has two modules:

• WebModule – that contains all the code that will appear to be the “public website”; and
• AppModule – gets loaded only after the user signs in (via a LoginScreen inside the WebModule) for security and performance reasons

I’m unsure of how to package the WAR. With one module (that contains an Entry Point), the normal structure seems to be this:

src/
    com.myapp
        MyApp.gwt.xml
    com.myapp.client
        MyApp.java
war/
    WEB-INF/
        lib/
        web.xml
    MyApp.css
    MyApp.html

But with 2+ modules, I’m confused as to where I can/should place the various files. I’d like to do something like this:

src/
    com.myapp
        WebModule.gwt.xml
        AppModule.gwt.xml
    com.myapp.client.modules
        WebModule.java (implements EntryPoint)
        AppModule.java (implements EntryPoint)
war/
    WEB-INF/
        lib/
        web.xml
    css/
        web-module.css
        app-module.css
    html/
        web-module.html
        app-module.html

But I’m unsure if this is “legal” (GWT and Java EE standards) structure or not, and I’m also unsure as to how to link “MyApp” with the “WebModule” so that WebModule is the first module downloaded when the user goes to http://www.myapp.com.

This is the right structure. You don’t have to create separate folders for HTML and CSS, though, as you only have two files in each.

You specify which file loads first, when users visit your domain, in web.xml file:

<welcome-file-list>
    <welcome-file>web-module.html</welcome-file>
</welcome-file-list>
