Re: Abstraction in RequestFactory

Maybe instead of parameterizing the method you should parameterize the class:

class BaseEntity<T extends BaseEntity> {

  public List<T> findPage(int start, int length, List<String> sortFields, List<Boolean> sortDirs) {

    …

  }

}

class TestEntity extends BaseEntity<TestEntity> { … }

but even then, it wouldn't work, because of the issue David mentionned: you'd have to repeat the method declaration inside TestEntityService (I guess using this workaround, it would work though).
