Integrating JD Edwards Enterprise One and Oracle Service Bus

Transcription

1 Integrating JD Edwards Enterprise One and Oracle Service Bus Overview This tutorial demonstrates how Oracle Service Bus (OSB) makes a service callout to a JD Edwards Enterprise One web service. OSB then routes the response to the appropriate business service, using content based routing. Use Case Incoming loan applications at a financial services company are routed through OSB to determine the appropriate business service to process the application, depending on the applicant s credit limit. OSB makes a service callout to JD Edwards Enterprise One to obtain the credit limit. If the credit limit is <= $100k, the application is routed to the regular-loan business service for processing; all other applications are routed to the jumbo-loan business service. The tutorial uses a file system to represent the two business services. Prerequisites 1. Oracle Service Bus 3.0 installation, available at Oracle BEA Product Downloads. 2. Access to JD Edwards Enterprise One 8.12/8.97, including a Business Services server. 3. JD Edwards setup to generate the WSDL for the published web service (see Section VIII). Time to complete: Approximately 2 hours.
