I’d like to know if its possible, by using GWT, Struts2 of JSF, provide to the client the resources (such as .css file) only if a page need it in that moment.

I don’t mean include the CSS on the page loaded in that moment, but if exist a mechanism that manages this process automatically.

    In JSF2 that’s possible by using <h:outputStylesheet> or <h:outputScipt> anywhere in your template or composite component. JSF will take care about putting it in the generated HTML <head>.

    E.g.

    <ui:composition
    xmlns:h="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
>
    <h:outputStylesheet library="css" name="specific.css" />
    <h:outputScript library="js" name="specific.js" />
    ...
</ui:composition>

    in combination with those files in /resources folder of the webcontent.

    • /resources/css/specific.css
    • /resources/js/specific.js

    Also, in a JSF2 UIComponent you can force loading of specific resources using the @ResourceDependency or @ResourceDependencies annotation.

    @ResourceDependency(library="css", name="specific.css")
public class CustomComponentWithCSS extends UIComponentBase {
    // ...
}

    @ResourceDependencies({
    @ResourceDependency(library="css", name="specific.css"),
    @ResourceDependency(library="js", name="specific.js")
})
public class CustomComponentWithCSSandJS extends UIComponentBase {
    // ...
}

    So whenever you use <custom:componentWithCSS> in your view code, JSF2 will include the annotated resources in the generated HTML <head>.
