Activate Subscription Service

Here we will see an example of how to activate a subscription service if you have the subscription and the installed item. You have to retrieve all the provisioning distributors where the installed item is distribute on, and then you have to find the services where are distributed on those distributors.
activateService.java
@EJB private CRMProcessSubscriptionServiceActivationBean processSubscriptionServiceActivationBean;    
    
public CRMDOSubscriptionAction activateService(CRMDOSubscription subscription,CRMDOInstalledItem installedItem){
    
    ArrayList<CRMDOSubscriptionService> servicesToBeActivated = new ArrayList<CRMDOSubscriptionService>();
    
    //create the subscription service activation data object
    SubscriptionServiceActivation subscriptionServiceActivation= processSubscriptionServiceActivationBean.constructSubscriptionServiceActivation(subscription);
    //the list of the product that will be activated from the subscription
    //in this example the product that will be activated will be retrieve based on the installed item
    Set<SubscriptionActionProduct> servicesToBeProcessed = new HashSet<SubscriptionActionProduct>();
    
    //retrieve the subscription installed item.
    CRMDOSubscriptionInstalledItem subscriptionInstalledItem = (CRMDOSubscriptionInstalledItem)subscriptionInstalledItemBean.load(subscription, installedItem);
    
    //retrieve the related distributions of the installed item
    ArrayList<CRMDO> installedItemDistributions = subProvisioningDistributionBean.load(subscriptionInstalledItem);
    
    //retrieve all the service distributions 
    ArrayList<CRMDO> serviceDistributions = subProvisioningDistributionBean.loadServiceDistributions(subscription, null);
    
    //retrieve all the subscription services which is distributed to same distributor as installed item
    for (int i=0;i<installedItemDistributions.size();i++)
    {
        CRMDOSubProvisioningDistribution installedItemDistribution = (CRMDOSubProvisioningDistribution)installedItemDistributions.get(i);
        
        for (int j=0;j<serviceDistributions.size();j++)
        {
            CRMDOSubProvisioningDistribution serviceDistribution = (CRMDOSubProvisioningDistribution)serviceDistributions.get(j);
            if (serviceDistribution.getProvDistributor().equals(installedItemDistribution.getProvDistributor()))
            {
                if (!servicesToBeActivated.contains(serviceDistribution.getSubService()))
                {
                    servicesToBeActivated.add(serviceDistribution.getSubService());
                }
            }
        }
        
    }
    
    for (int i=0;i<servicesToBeActivated.size();i++)
    {
        CRMDOSubscriptionService subscriptionService =(CRMDOSubscriptionService)servicesToBeActivated.get(i);
        //create a new subscription action product data object where you will define the product that will be process by the action
        SubscriptionActionProduct subscriptionActionProduct =new SubscriptionActionProduct();
        subscriptionActionProduct.setIsDeleted(new Integer(0));
        subscriptionActionProduct.setProduct(subscriptionService.getProduct());
        subscriptionActionProduct.setSubService(subscriptionService);
        subscriptionActionProduct.setIsSelected(new Integer(1));
            
        servicesToBeProcessed.add(subscriptionActionProduct);
    }
    
    subscriptionServiceActivation.setServicesToBeProcessed(servicesToBeProcessed);
    
    //submit the subscription service activation data object in order to remove the product from subscription 
    //As a result is the subscription action data object.
    //the subscription action data object is the object which contains all the information about the action you perform on the subscription
    CRMDOSubscriptionAction subscriptionAction = processSubscriptionServiceDeactivationBean.submit(subscriptionServiceActivation);
