About Proxies and Examples
This release of the documentation includes code snippets in most chapters. These code snippets illustrate many product features and can serve as a basis for developing your own applications.
The code snippets in this Developer’s Guide are in C#, but there are differences across these examples depending on the generated proxy and the language. For instance, in the Agent Interaction SDK Services API Reference for the .NET Proxy, C# service interfaces are defined in accordance with the following rule: I<service_name>Service. In the generic Agent Interaction SDK 7.6 Services API Reference for the Java Proxy, on the other hand, service interfaces are defined in accordance with the following rule: <service_name>Service.
You can do any of the following:
- Use a toolkit to generate a proxy from the provided WSDL files.
- Use one of the provided .NET proxies available on the product CD in the tools/ directory.
- Use one of the provided Java proxies available on the product CD in the tools/ directory.
Then, use the chosen proxy to build your desktop application using the Agent Interaction SDK Service that the Agent Interaction Services Libraries expose.
Generating a SOAP Proxy
You can use a toolkit to generate a SOAP proxy from the provided WSDL files—for example, Apache AXIS toolkit, version 1.1 or 1.3, for Java development (for further information, see: http://ws.apache.org/axis/java/user-guide.html).
With a SOAP proxy, use the GIS session service to connect your client application and to set options. Refer to the Statistics SDK 7.6 Web Services Developer’s Guide for further details about the session service, and see this chapter’s API Overview for further details about available options.
Opening a Session
The first step your Agent Interaction SDK Services client application must perform is to open a session in GIS to get a session ID, which must be passed in the URL of all SOAP requests. As your application creates services, for each service, specify the ENDPOINT_ADDRESS_PROPERTY and the session ID as shown in the following code snippet.
/// creation of an agent service using a stub created with /// Apache Axis toolkit 1.1
import com.genesyslab.www.ail.*;
import com.genesyslab.www.ail.agent.*;
//Creating a gis session - GIS server location set when
//generating the stub
SessionServiceServiceSoapBindingStub sessionService =
(SessionServiceServiceSoapBindingStub) new SessionServiceServiceLocator().getSessionServiceService();
// Time out after a minute
sessionService.setTimeout(60000);
Identity id = new Identity();
id.setPrincipal("example");
id.setCredentials("");
sessionId = sessionService.login(id);
System.out.println("sessionId= " + sessionId);
sessionService._setProperty( sessionService. ENDPOINT_ADDRESS_PROPERTY, sessionService._getProperty( sessionService.ENDPOINT_ADDRESS_PROPERTY)
+ "?GISsessionId=" + sessionId);
// Accessing Services
String[] value = sessionService.getServices(new java.lang.String[] { "GIS_INTERACTIONSERVICE"});
AgentServiceSoapBindingStub agentService =
(AgentServiceSoapBindingStub) new AgentService_ServiceLocator().getAgentService();
agentService.setTimeout(60000);
/// Property used to pass session id in requests
agentService._setProperty(
agentService.ENDPOINT_ADDRESS_PROPERTY,
agentService._getProperty( agentService.ENDPOINT_ADDRESS_PROPERTY) +"?GISsessionId=" + sessionId);
// then using agent service is similar to C#
// logging an agent
LoginVoiceForm loginVoiceForm = new LoginVoiceForm();
loginVoiceForm.setLoginId(loginId);
loginVoiceForm.setWorkmode(WorkmodeType.AFTERCALLWORK);
MediaInfoError[] values = agentService.login(agentId, placeId, loginVoiceForm, null);Using the .NET Proxy
You can use the provided .NET proxy to minimize session management tasks and to simplify service creation. This proxy is available in the tools/ directory on the GIS Product CD.
This section presents how to connect to GIS, and how to use XML and options for instantiating this connection.
Service Factory
The com.genesyslab.ail.ServiceFactory class is the entry point for the .NET proxy. You must create a ServiceFactory object in order to connect. The connection can be synchronous or asynchronous, according to the method called:
-
ServiceFactory.createServiceFactory()—At creation, the factory instance tries to connect synchronously to GIS. If the connection fails, it raises an exception.
-
ServiceFactory.asyncCreateServiceFactory()—After the factory creation, the factory instance tries to connect asynchronously to GIS until a connection succeeds or the factory is released. To monitor the connection status, you must specify an IServiceFactoryListener listener at factory creation.
When you create the factory (synchronously, or asynchronously), you must specify parameters to configure your connection:
-
You can fill a Hashtable and pass it at ServiceFactory creation. See XML Configuration File for .NET for details about options.
-
You can use an XML file to configure your ServiceFactory object.
Using an XML file is simple: write your own XML file that defines the factory parameters, or use the default
ail-configuration.xml
file; then, indicate the factory parameters to be used.
The following code snippet shows the ServiceFactory creation based on the
WebServicesFactory factory defined in the ail-configuration.xml file.
// Instantiation of a ServiceFactory to make the connection
ServiceFactory myServiceFactory =
ServiceFactory.createServiceFactory("WebServicesFactory", null, null);See XML Configuration File for .NET for further details.
Access Services
To access the available services, you create them by calling the createService() method of your instantiated factory, as shown in the following code snippet.
IXxxService iservice =
myServiceFactory.createService(typeof(IXxxService), null) as IXxxService; If the Hashtable parameter is null in the createService() call, the Agent Interaction Service layer takes into account the current context of the factory. Otherwise, the Agent Interaction Service layer uses the specified Hashtable for service creation.
The following code snippet shows how to create an agent service:
IAgentService myAgentService = myServiceFactory.createService(typeof(IAgentService), null) as IAgentService;XML Configuration File for .NET
In your XML configuration file, or in the default ail-configuration.xml file, you must specify for the factory tag one of the following two attributes with their url option, according to the protocol used to communicate with GIS:
-
For GSAP:
-
PropFactory—The factory name.
-
url option—The value is prop://[Server address]:[Server port].
-
For SOAP:
-
WebServicesFactory
—The factory name.
-
url option—The value is http://[Server Address]:[Server Port]/gis.
-
SOAP
-
AilWebServicesFactory—The factory name.
-
Url option—The value is http://[Server Address]:[Server Port]/soa.
-
GSAP
-
GSAPServiceFactoryImpl
—The factory name.
-
url option—The value is prop://[Server Address]:[Server Port].
-
handling agent activity, such as login and logout.
-
handling voice interactions such as answering, calling, and callback.
-
handling e-mail interactions.
-
handling outbound campaigns.
-
using the Standard Response Library.
-

Using the Java Proxy
You can use the provided Java proxy to minimize session management tasks and to simplify service creation. This proxy is built from the Apache Axis toolkit, version 1.3, and is available in the tools/ directory on the GIS Product CD.
This section presents how to connect to GIS, and how to use XML and options for instantiating this connection.
Service Factory
The com.genesyslab.soa.client.ServiceFactory class is the entry point of the proxy. You must create a ServiceFactory object in order to connect. The connection can be synchonous or asynchronous, according to the method called.
Except for the default configuration file name, the process and the method to be called are identical to those described in Service Factory.
Access Services
To access the available services, you create them by calling the createService() method of your instantiated factory, as detailed in Access Services.
XML Configuration File for Java
In your XML configuration file, or in the default proxy-configuration.xml file, you must specify for the factory tag one of the following two attributes with their url option, according to the protocol used to communicate with GIS:
Your application reads the XML configuration file—by default, proxy-configuration.xml
—to determine which protocols and options should be used for instanciating its connection to GIS.

<option name="notification.reachableURL" value="http://[client host]:[client port]"/>
</factory>
</configuration>GIS License
SOAP
The GIS_INTERACTIONSERVICE license is checked out when your application needs to call the ServiceFactory.createFactory() method. To check the license in, your application calls the ServiceFactory.releaseFactory() method.
In a scenario where the agent logs out and the application properly terminates, your application should release the ServiceFactory instance when the application ends; this frees the agent’s license.
In an application crash scenario, the license is checked in when the GIS session ends, as is also the case with the GIS_CONFIGURATION_SERVICE and GIS_STATSERVICE licenses.
GSAP
The GIS_INTERACTIONSERVICE license is checked out when your application connects. Then, the license is checked in when your application disconnects from GIS, regardless the reason of the disconnection (crash or regular shutdown).
HTTP Redirections
Unlike with the .NET proxy, you cannot enable or disable redirections at compilation or runtime. In Java, the Axis client handles the HTTP connection through a library, which is defined in the wsdd client file, and relies on the v3.0.1 Jakarta HTTP client (see HttpClient Home.)
For instance, to enable redirections, you should disable the HttpCommonsSender library in the Java client that implements the proxy library:
context.setProperty("EnableHttpCommonsSender", "false");Then, you can provide your own client-config.wsdd file which defines the transport layer, as shown below.
<?xml version="1.0" encoding="UTF-8"?>
<deployment name="defaultClientConfig"
xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<globalConfiguration>
<parameter name="disablePrettyXML" value="true"/>
<parameter name="enableNamespacePrefixOptimization" value="false"/>
<parameter name="sendMultiRefs" value="false"/>
</globalConfiguration>
<transport name="http" pivot="java:com.genesyslab.soa.impl.channel.axis.handler.HTTPSender" />
<transport name="https" pivot="java:org.apache.axis.transport.http.CommonsHTTPSender"/>
<transport name="local" pivot="java:org.apache.axis.transport.local.LocalSender"/>
</deployment>To develop a transport layer, you should extend the org.apache.axis.handlers.BasicHandler class. Refer to the official Axis documentation for further information.
API Overview
The Agent Interaction Services API works with the mirroring services available in GIS. Typically, your application is a client application, integrating Agent Interaction Services to perform agent actions and to communicate data and events with the Genesys Framework, as shown in the figure below.
Services Integrated in an Agent Application
Your application deals with services that transparently hide GIS and the Genesys Framework, which handles information and CTI objects. These services provide the following features:
One particularity of the Agent Interaction Services API is its service approach design
. This means that a service deals with dedicated information concerning a set of remote objects. For example, the agent service deals with agent data only.
Building an Application Using Services
Take the following steps (a general strategy) to build your application on the Agent Interaction Services API:
Connect your application. See Opening a Session.
-
Get an event service. The Event Service.
-
Get an agent service. The Agent Service.
-
Subscribe to events.
-
Get the services required to implement your application features.
-
Update your application any time you retrieve an event according to possible actions or status changes.
The Remote Services
When using the Agent Interaction Services API, you are dealing with remote services integrating the Agent Interaction Layer library. This library is part of the Genesys Agent Interaction (Java API). See the Agent Interaction SDK Java documentation for full details of AIL features.
The AIL library internally implements models of Genesys products, such as Framework voice calls, e-mail, outbound campaigns, and so on.
The remote services are exposed in GIS, as shown in the following figure.
The Remote Services and the Genesys Interface Server
On the GIS side, the remote services implement the AIL library, which internally handles models of the Genesys Framework. On the agent-desktop-application side, the integrated services hide the interactions with the remote services which encapsulate the AIL library.
The AIL library maintains models of the Genesys objects used by your application. These objects might include, for example, DNs, a Places, agents, or interactions. The native AIL library API offers interfaces to perform actions on these objects, and the library core internally handles the state models, as illustrated in the following figure.
The Remote Services and the AIL Internal Core
The numbered labels in the above figure describe the following actions:
- Implementation of an AIL Interface dealing with a core object
- Calling an AIL object method
- AIL Sending a set of requests
- AIL Receiving Events
- AIL core updating core object models
- AIL sending events to the Event Service
As shown in the above figure, the AIL core notifies the remote services with events when the states of objects or data change. For example, if your service requests an agent login on a media type, once the agent is logged in, the AIL core notifies the event service that the agent status on the media is now READY or NOT_READY. If your application has registered to listen to events on the agent, it receives the event and can inspect the data.
Using the Services
The Agent Interaction Services API provides a set of services. A service is an interface dealing with a group of objects. For example, an interaction service gives access to interactions’ data. A single request can apply to a group of several interactions.
Service Concept
Services are agent-oriented; that is, services are designed to fulfill requests of agent type and should be used for this purpose.
The Agent Interaction Services API represents services suitable to perform agent actions and to retrieve any data required by an agent-oriented application. How you make use of the various services is a matter of your application design.
Your application integrates at least two services: the agent service and the event service, as shown in the following figure.
Using the Services in Your Agent Desktop Application
To properly use other services, your application requires:
-
An agent service—This service manages agent actions and data; without an agent logged in with this service, some services cannot fulfill actions and data requests.
-
An event service—Your application must update according to the data propagated in events which are published in this service.
Possible Actions
The Agent Interaction Service API is designed to implement agent desktop applications. Therefore, services have been designed to perform agent actions that affect the components managed by the Genesys Framework.
For example, getting ready, logging in, and logging out on media are actions handled by the IAgentService interface, and performed by calls to the corresponding methods.
However, a given service’s actions might not all be available at a given point in time. An obvious example is an agent not being allowed to become READY on media where he or she has not yet logged in.
Thus, to perform a particular action, your application must first check to see if this action is possible:
-
Actions are identified in the <service_name>Action
enumeration.
-
Possible actions are provided with attributes of the I<service_name>Service
interface attributes.
-
Possible actions are updated and propagated with events.
A good use of possible actions is enabling or disabling graphical components that the agent uses to perform actions.
Statuses
The services interact with objects and provide you with their statuses during runtime.
-
Statuses are identified in the *Status enumeration of service namespaces.
-
Status access is provided with attributes
of the I<service_name>Service interface.
-
Status changes are propagated in events.
You should base your application design on these statuses. For example, in a GUI context, if a call status is IDLE (terminated), the associated GUI components have no need to be visible anymore.
