This example shows how to manage a complete case with solution and execute some adaptation methods. Now the case has also a solution bean with a few attributes. That way, the structure of the case is:

 Case
  |
  +- Description
  |       |
  |       +- caseId
  |       +- HollidayType
  |       +- Price
  |       +- NumberOfPersons
  |       +- Region
  |       |     |
  |       |     +- regionId
  |       |     +- regionName
  |       |     +- NearestCity
  |       |     +- Airport
  |       |     +- Currency
  |       +- Transportation
  |       +- Duration
  |       +- Season
  |       +- Accomodation
  |       +- Hotel
  |
  +- Solution
          |
          +- id
          +- price
          +- hotel
 

Solution is stored in the TravelSolution bean (CaseComponent). This bean could be saved into a separate table, but here were are going to show how to use the same table than the description. This way, the mapping is:

• Description is saved into the travel table.
• Solution is also saved into the travel table (using different columns, of course).
• Region (the compound attribute) of the description is saved into its own table region.

Following picture shows how attibutes are mapped into the database:

To configure these mapping we must modify or create the following files:

• databaseconfig.xml
  In this file we include the solution class namea and its mapping file:

   <SolutionMappingFile>es/ucm/fdi/gaia/jcolibri/test/test4/TravelSolution.hbm.xml</SolutionMappingFile>
   <SolutionClassName>es.ucm.fdi.gaia.jcolibri.test.test4.TravelSolution</SolutionClassName>
   

• TravelSolution.hbm.xml
  This is a simple mapping file for the solution bean:

   <hibernate-mapping default-lazy="false">
     <class name="es.ucm.fdi.gaia.jcolibri.test.test4.TravelSolution" table="travel">
       <id name="id" column="caseId"></id>
       <property name="price" column="Price"/>
       <property name="hotel" column="Hotel"/>      
     </class>
   </hibernate-mapping>
   

Doing these changes the connector will manage the new case structure without problems.

This method also shows how to perform a simple adaptation based in the DirectProportion method that modifies the value of an attribute of the solution depending on the value in the query and retrieved case of other attribute of the description.
