= Analysis =


== Overview ==
The Sophie 2 Server Facade layer provides interface which is the same on both the server and the client sides for manipulating the resources on the server. The Facade layer accesses the Server core logic.


== Task requirements ==
This task must improve th model of the facade logic for accessing resources. For now the facade has UserManager and GroupManager implemented, so at least BookManager can be created.
 * Create class in the facade, which provides the core functionality for accessing books.
 * What else should be added, depends on the result of [wiki:S2S_CORE_RESOURCES_R0].
 * Refactor the current code to use the new facade classes. This includes jsps, servlets.
 * Write appropriate unit tests. [[BR]]
Tha facade must also be able to get/change/upload any kind of resource. The procedure should be the similar as described above.


== Task result ==
Source code.

== Implementation idea ==
For every major kind of resource, create an interface in org.sophie2.server.facade, and its implementation in org.sophie2.server.facade.impl. For example, for the book resource create:
 * Interface BookManager in org.sophie2.server.facade, which uses the BookService class. The methods there should be able to add/save/delete books, get all books, search books by different criterias
 * Class ServerBookManager, which implements BookManager.
