2 JUMP: Discover Libraries It allows to extract UML Profiles from Java annotations Example shown: JPA Library input (JPA Library) To execute it: right click on the jpa2 project and select Model Discovery Toolbox -> UML Profile Discovery output (UML Profile) More UML Profiles have been discovered by JUMP They can be installed as Eclipse plugins Alexander Bergmayr, Michael Grossniklaus, Manuel Wimmer, Gerti Kappel: JUMP - From Java Annotations to UML Profiles.

4 JUMP: Discover PSM + Libraries (RE) Execute JUMP on the petstore-app In order to execute it, right click on the petstore-app and select Model Discovery Toolbox -> Profiled UML Model Discoverty input (Petstore application) output (PSM of the Petstore) output (Profile with stereotypes of the Petstore) Hugo Brunelière, Jordi Cabot, Grégoire Dupé, Frédéric Madiot: MoDisco: A model driven reverse engineering framework.

7 1. Understanding (I) (RE) Based on the JPA annotations, we are interested only in the domain model input (PSM of the Petstore) Some profiles of the UML Profile Store are also taken as input output (Sliced PSM of the Petstore containing the domain model) launch configuration

8 Cloudifying through JUMP (1) Validation ShoppingCart - order Line «Id» - lineid: long «Id» - orderid: long «OneToMany»{cascade=[All]} «Size»{min=1} «Embedded» - orderlines [0..*] - delivery JPA «Embeddable» Annotated Application Classes at PSM Level UML Class Diagram Source code

9 2. Understanding (II) (RE) We want to obtain a PIM from the PSM Remove all stereotypes Turn some plain associations into composition associations Output (PIM of the Petstore containing the domain model) Input (Sliced PSM of the Petstore containing the domain model) launch configuration

11 3. Modernisation (I) (FE) Refine the PIM into a PSM cloudcompatible Addition of the Objectify Profile Output (PSM of the Petstore domain model with stereotypes from Objectify) Input (PIM of the Petstore containing the domain model) launch configuration

13 4. Modernisation (II)(FE) The PSM is further refined by adding service classes They contain Objectify instructions Output (PSM of the Petstore domain model with service classes) Input (PSM of the Petstore domain model with stereotypes from Objectify) launch configuration

15 5. Code Generation (FE) Extension of the Acceleo UML2 to Java code generator Output (auto-generated code of the Petstore) Input (PSM of the Petstore domain model with service classes) launch configuration
