Dans la stratégie Passthrough dans VM, créez l'objet ServiceClientFactory lors de l'appel de l'API à partir de la même machine virtuelle Java que le serveur AEM Forms ou LiveCycle.
Environnement
AEM Forms/LiveCycle
Étapes
Nous écrivons généralement le code suivant lors de l'appel de l'API Java LiveCycle / AEM Forms JEE via un client distant pour l'obtention de l'objet ServiceClientFactory :
Properties connectionProps = new Properties();
connectionProps.setProperty("DSC_DEFAULT_EJB_ENDPOINT", "remote://localhost:4447");
connectionProps.setProperty("DSC_TRANSPORT_PROTOCOL", ServiceClientFactoryProperties.DSC_EJB_PROTOCOL);
connectionProps.setProperty("DSC_SERVER_TYPE", ServiceClientFactoryProperties.DSC_JBOSS_SERVER_TYPE);
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_USERNAME, "administrator");
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_PASSWORD, "password");
//Create a ServiceClientFactory object
ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);
Cependant, dans le cas où nous voulons appeler ces API dans un DSC ou 'Execute Script' dans le flot de travail, nous pourrions facilement utiliser la stratégie d'invocation in vm direct pass through (qui est par défaut).
Utilisez le code ci-dessous pour obtenir l'objet ServiceClientFactory à l'aide de la stratégie de diffusion directe In VM.
ServiceClientFactory factory = ServiceClientFactory.createInstance();
Informations supplémentaires
Pour plus d’informations, voir Javadoc. L'invocation EJB (point de terminaison) peut être utilisée à distance ou à partir de la même jvm. Dans AEM Forms 6.x avec Jboss 6.x, en utilisant le point de terminaison EJB, nous obtenons l'exception suivante :

Bien que ce soit inoffensif, nous pouvons éviter cela facilement en utilisant la stratégie In VM, au cas où nous l'invoquerions par le même jvm.
