Reflection tool for working with annotations

Hello,
I am looking for a tool, that provides some functionality for working with annotations by reflection. Something with methods for getting all annotations of concrete annotation type, and so on, functionality, that is provided by APT annotation processor. Do anybody knows about something? I have founded a project Google Reflections, that could be the one, but I have some problems to make it work (probably my own unpracticality). So if there is anyone that has some expierence with it, I would appreciate some walkthrough for start (rather through email).
Thanks,
Milan Nosal

I keep using the java reflection API to find the annotations where I need to work with them, for example,

Code:

---

  /**
  * Find the declared methods in a class that have the specified annotation.
  * @param ref
  * @param annotationClass
  * @return
  */
  public static Collection<Method> findMethodsWithAnnotation(Class<?> ref, Class<? extends Annotation> annotationClass) {
    Collection<Method> results = new ArrayList<Method>();

    Method[] methods = ref.getMethods();
    for (int i = 0; i < methods.length; i++) {
      Method method = methods[i];
      Annotation annotation = method.getAnnotation(annotationClass);
      if (annotation != null) {
        results.add(method);
      }
    }
    return results;
  }

If you want to "find all classes that have an annotation" on the entire classpath, I have found the project "scannotation" helpful. This is important for if you have a fairly large code base, such as many many jar files in your application, as they use a mechanism to read the .class file structure from within a given package starting point to find annotations outside of the class loader; doing it with the class loader can waste the permgen memory space by loading classes that are not ever used in your application.

Thanks for prompt answer. I am looking for something like scannotation. Scanotation is not exactly what I need, but it seems to be really helpful.
