Implement the client library

In this step, you add convenience methods that hide the complexity of creating the different GetTutorialStore requests.

Procedure

1. Open the SOITutorialStore-Client/src/com.mycompany.commerce.soitutorialstore.facade.SOITutorialStoreFacadeConstants class.

2. Add the following constants to represent the open store and close store process actions.

   /**
   * The Open Store process action.
   */
   public static String PROCESS_ACTION_OPEN = "Open";
   
   /**
   * The Close Store process action.
   */
   public static String PROCESS_ACTION_CLOSE = "Close";
   

3. Save the SOITutorialStoreFacadeConstants class.

4. Open the com.mycompany.commerce.soitutorialstore.facade.client.SOITutorialStoreFacadeClient class.

5. Add the following client methods that build the appropriate BOD:

   /**
   * This method composes a Process BOD with an Action of 'Close' and sends
   * the BOD to the TutorialStore-Server.
   */
   public AcknowledgeTutorialStoreDataAreaType closeStore(String storeId) {
   final String METHODNAME = "closeStore(String storeId)";
   
   ProcessTutorialStoreType processTutorialStore = getSOITutorialStoreFactory()
   .createProcessTutorialStoreType();
   ProcessTutorialStoreDataAreaType dataArea = getSOITutorialStoreFactory()
   .createProcessTutorialStoreDataAreaType();
   processTutorialStore.setDataArea(dataArea);
   
   java.util.List expressions = new ArrayList();
   expressions.add(createActionExpression(
   SOITutorialStoreFacadeConstants.PROCESS_ACTION_CLOSE, SelectionCriteriaHelper.STR_XPATH_LANG, SOITutorialStoreFacadeConstants.XPATH_STORE));
   dataArea.setProcess(createProcessVerb(expressions));
   
   StoreIdentifierType storeIdentifier = CommerceFoundationFactory.eINSTANCE
   .createStoreIdentifierType();
   storeIdentifier.setUniqueID(storeId);
   
   TutorialStoreType tutorialStore = getSOITutorialStoreFactory()
   .createTutorialStoreType();
   tutorialStore.setStoreIdentifier(storeIdentifier);
   dataArea.getTutorialStore().add(tutorialStore);
   
   AcknowledgeTutorialStoreDataAreaType acknowledgeTutorialStoreDataArea = processTutorialStore(
   processTutorialStore).getDataArea();
   
   return acknowledgeTutorialStoreDataArea;
   }
   
   /**
   * This method composes a Process BOD with an Action of 'Open' and sends the
   * BOD to the TutorialStore-Server.
   */
   public AcknowledgeTutorialStoreDataAreaType openStore(String storeId) {
   final String METHODNAME = "openStore(String storeId)";
   
   ProcessTutorialStoreType processStore = getSOITutorialStoreFactory()
   .createProcessTutorialStoreType();
   ProcessTutorialStoreDataAreaType dataArea = getSOITutorialStoreFactory()
   .createProcessTutorialStoreDataAreaType();
   processStore.setDataArea(dataArea);
   
   java.util.List expressions = new ArrayList();
   expressions.add(createActionExpression(
   SOITutorialStoreFacadeConstants.PROCESS_ACTION_OPEN, SelectionCriteriaHelper.STR_XPATH_LANG, SOITutorialStoreFacadeConstants.XPATH_STORE));
   dataArea.setProcess(createProcessVerb(expressions));
   
   StoreIdentifierType storeIdentifier = CommerceFoundationFactory.eINSTANCE
   .createStoreIdentifierType();
   storeIdentifier.setUniqueID(storeId);
   
   TutorialStoreType tutorialStore = getSOITutorialStoreFactory()
   .createTutorialStoreType();
   tutorialStore.setStoreIdentifier(storeIdentifier);
   dataArea.getTutorialStore().add(tutorialStore);
   
   AcknowledgeTutorialStoreDataAreaType acknowledgeStoreDataArea = processTutorialStore(
   processStore).getDataArea();
   
   return acknowledgeStoreDataArea;
   }
   

6. Save the SOITutorialStoreFacadeClient class.

7. Organize the imports for the SOITutorialStore-Client project:

   1. Open the Java perspective in WebSphere Commerce Developer.

   2. Right-click the SOITutorialStore-Client\src folder and select Source.

   3. Select Organize Imports.
