Siebel eAI and Java/J2EE

Siebel eBusiness Applications provide standards-based technologies that allow you to access J2EE components from Siebel applications and support the creation of Java/J2EE components to access Siebel objects.

Accessing Java/J2EE Components from Siebel Applications

Siebel eBusiness Applications provide two mechanisms for invoking Java/J2EE components (JSP, Servlets, or EJBs):

When interacting with J2EE components published as a Web Service, Siebel applications can consume the WSDL (Web Service Description Language) document describing the service and operations, and generate a proxy Business Service allowing the Siebel eBusiness Application to invoke the Web Services just like a local object. When the Business Service is invoked, the Object Manager detects that the Business Service is a proxy to a Web Service and generates the appropriate SOAP (Simple Object Access Protocol) message and dispatches the request using a configured transport such as HTTP.

Additionally, Siebel eAI allows you to interact with J2EE components using the Outbound HTTP transport adapter. You can use this when including external content within the Siebel user interface, or when the component you need to interact with does not support a Web Service (SOAP or WSDL) interface.

Accessing Siebel Applications from a Java/J2EE Component

Java/J2EE components can request information from Siebel applications using a variety of methods including:

The Java Data Bean is a collection of Java classes that allow developers to interact with a variety of Siebel objects such as business objects, business components, and so on. Using this interface, you can develop Java/J2EE components that interact with Siebel applications.

The Siebel Resource Adapter plays a central role in the integration and connectivity between Siebel applications and a Java application server. It serves as the point of contact between application components, application servers and enterprise information systems. A resource adapter, along with the other components, must communicate with each other based on well-defined contracts that are specified by the J2EE Connector Architecture.

Web Services are emerging as an important technology for exposing application functionality independent of the underlying technology used to provide that functionality. Release 6.x introduced the notion of Business Services that could be invoked through XML over HTTP and MQSeries. This functionality is now the basis for supporting Web Services. Siebel eBusiness Applications provide support for Simple Object Access Protocol (SOAP) and Web Services Definition Language (WSDL). These two standards provide the basis for Web Services and allow for interoperability between .NET, J2EE, and leading packaged applications such as Siebel eBusiness Applications.

Object Interfaces

Siebel applications support several programmatic interfaces to facilitate communication between external applications and Siebel applications. These interfaces include:
