init on servlet level

[Andrei]

For GAE, if I have stand alone servlet, I would use
Where do I initialize variables (like cache here) per servlet instance
with Click?
Thanks

  // --------------------------------
  public void init() throws ServletException {

    try {
      CacheFactory cacheFactory = CacheManager.getInstance().getCacheFactory();
      cache = cacheFactory.createCache(Collections.emptyMap());
    } catch (CacheException e) {
      log.severe( "could not init Cache" );
    }

  }
