GuiceServletContextListener.getInjector should have one param: servletContext

_From [gianmarco.gherardi](https://code.google.com/u/gianmarco.gherardi/) on February 16, 2011 11:04:39_

This way, configuration parameters can be passed as constructor parameter to object. For example, this is possible in normal Java application:

public static void main(String[] args) {
  String fooServerAddress = args[0];
  Injector injector = Guice.createInjector(new FooModule(fooServerAddress));
  FooClient client = injector.getInstance(FooClient.class);
  ...
}

In Servlet application this should became:

public class AppGuiceServletContextListener extends GuiceServletContextListener {
  `@`Override
  protected Injector getInjector(ServletContext servletContext) {
    String fooServerAddress = servletContext.getInitParameter("fooServerAddress");
    return Guice.createInjector(new FooModule(fooServerAddress));
  }
}
