Access to a Siebel Application from a Java or J2EE Component

The ways that a Java and J2EE component can request information from a Siebel application include:

  • Java Data Bean. The Java Data Bean is a collection of Java classes that allow a developer to interact with a variety of Siebel objects, such as business objects, business components, and so forth. With this interface, you can develop Java and J2EE components that interact with a Siebel application.

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

  • Web Service. Web Services are emerging as an important technology for exposing application functionality that is independent of the underlying technology used to provide that functionality. Release 6.x introduced business services that could be called through XML over HTTP and MQSeries. This functionality is now the basis for supporting Web Services. Siebel Business 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 Business Applications.

    For more information, see About Web Services.

  • Java Message Service. Enterprise messaging is recognized as a tool for building enterprise applications. The Java Message Service (JMS) is a standard Java API that is used to access an enterprise messaging system. JMS is part of the Java 2 Platform, Enterprise Edition (J2EE). JMS supports the ability to asynchronously send and receive business data and events. JMS defines a common enterprise messaging API that supports a wide range of enterprise messaging products. JMS supports both message queuing and publish and subscribe styles of messaging.

    JMS is not a separate product. It is the specification of a common API for enterprise messaging. A JMS provider that is supplied by an enterprise messaging vendor is required in order to use it. Using the Java Business Service (JBS) feature, the JMS Transport is a feature that provides access to the JMS providers for a third-party vendor. A JMS provider is the implementation of the JMS API for a particular vendor. For example, IBM implements a JMS provider for their MQSeries product, and BEA implements a JMS provider for their Weblogic product.
