You can't use the built-in EnvironmentLoaderListener because it doesn't use
injection to build the Environment. However, you should be able to extend
it and override #createEnvironment(ServletContext) to use an injected
CdiWebEnvironment instance:
public class CdiEnvironmentLoaderListener extends EnvironmentLoaderListener
{
@Inject
private CdiWebEnvironment environment;
protected WebEnvironment createEnvironment(ServletContext sc) {
// Do your initialization here
return environment;
}
}
I haven't actually tried this because I ended up writing my own
version of EnvironmentLoaderListener,
but this should work.
