How to reference file resource in a JSF Application

I want to dynamically reference an XSD from a bean, how is this possible? I already added the XSD to the project, so it's located somewhere in the GlassFish domain.

Use the ExternalContext.

If you want to load the resource in the bean, do it via getResource or getResourceAsStream:

InputStream stream = FacesContext.getCurrentInstance().getExternalContext()
    .getResourceAsStream("/foo.xsd");

If you want to return a URL to the resource, use getRequestContextPath to get the path relative to the host root:

ExternalContext ext = FacesContext.getCurrentInstance()
    .getExternalContext();
String path = ext.getRequestContextPath();
path += path.endsWith("/") ? "foo.xsd" : "/foo.xsd";
String url = ext.encodeResourceURL(path);
