Apache Tapestry: Absolute path to assets in META-INF/assets

The solution here helps me get absolute path to assets in class-path (context) Tapestry 5 - Dynamically generate URL of file in web app context folder in Java code

Is there a way to do the same for assets stored in META-INF/assets (Tapestry 5.4 way of storing assets)?

Specifically, I'd like to inject the path of the a .html (static) file I've created in META-INF/assets folder..

at the moment I have:

public String getMyHtml() {
    String clientURL = assetSource.getContextAsset("html/myhtml.html", locale).toClientURL();

    return clientURL;
}

and the tml file has:

"{ url: '${getDeltaHtml()}' }"

This works if "myhtml.html" file is located in class path folder (WEB-INF). It does not work if its in META-INF/assets folder, which is where I'd like to put it

Solution

  • You can get hold of the assets stored under assets by this.

    First you have to inject the following.

    @Inject
private AssetSource assetSource;

@Inject
private ThreadLocale threadLocale;

    After that you can use the following to get the Assets.

    Asset asset = assetSource.getAsset(null, "classpath:META-INF/assets/myhtml.html", threadLocale.getLocale());
