Answer 1

You can do it without passing in the class:

class Model {
  Class c = (Class) DAOUtil.getTypeArguments(Model.class, this.getClass()).get(0);
}

You need two functions from this file: http://code.google.com/p/hibernate-generic-dao/source/browse/trunk/dao/src/main/java/com/googlecode/genericdao/dao/DAOUtil.java
