Using Java Code Generated by Siebel eBusiness Applications

The following two sections contain code samples for both managed and non-managed environments.

Managed Code Sample

The following is a code sample using the Siebel Resource Adapter in a managed environment. The SiebelAccountBean class, which is described in this section, provides code examples that show how to perform the following tasks:

The following code uses the code generation facilities provided in Siebel Tools. For more information, see The Siebel JavaBean Wizard for both business services and integration objects. By using the code generation facilities, many of the complexities of the J2EE Connector specification (Interactions, ConnectionSpec, CCI) have been abstracted and encapsulated into a consistent, JavaBean-based interface.
