Check out the project A10T25_26_Model_Transformation from your SVN repository.

Your task is to partly transform a PIM model src/model/HotelDomain²⁾ to an EJB3-based PSM, see the profile in src/model/ejb3.umlprofile. We will use a slightly modified variant which contains the plug-in point CreditCardInstitute. Your starting point is the src/m2m/archetypesToejb3.ext extension file.

Your mapping should include the following:

• map party/thing/place, role, moment_interval and mi_detail to Entity bean.
• map plugin_point to a Session bean, ignore the needed local/remote interfaces here.
• Set the type of all Properties to UMLPrimitiveTypes::Integer³⁾ for all Class Properties without a defined type⁴⁾

• Verify your modifications with the check files src/validation/ConstraintsPackage.chk⁵⁾ and src/validation/ConstraintsMembers.chk⁶⁾

The following extensions are helpful for the task:

• allOwnedElements(): all sub elements
• typeSelect(Stereotype/UML Class): selects elements of a list by their (stereo)type
• the profile helper extensions in m2m/profileUtils.ext

General hints:

• Concatinate extension calls with call → call2
• The last element in an extension is returned if a return type is given
• Have a look at the abstract syntax in the file src/model/HotelDomain.uml⁷⁾ to understand the model's structure

Generate Java classes for your model. Concentrate on the classes, annotations, properties and associations. You might omit the generation of methods. The extension getAssociatedClasses(Class) is - again - helpful here.

Use template/JavaSource.xpt as starting point.
