Wicket On Google App Engine (GAE) – Deployment Configuration

Just a quick tip – generally with Wicket we want to supply our application with a way to choose between “Development” vs. “Deployment” mode automatically, so that we can get stack traces etc. during development and disable development features for deployment. Google App Engine sets a convenient JVM property to enable this -

class MyWicketApplication extends Application {
   .....
    private boolean isProd =
        "Production".equalsIgnoreCase(
            System.getProperty("com.google.appengine.runtime.environment"));

    @Override
    public String getConfigurationType() {
        return (isProd ? "DEPLOYMENT" : "DEVELOPMENT");
    }
}

Bam – Wickety GAE love!
