How Can I Get an Instance ID for Oracle ESB?

A new XPath function was added in 10.1.3.3 to get instance IDs. This section provides an example in which you invoke a BPEL process from an ESB process and pass the ESB instance ID to the BPEL process, along with other data. 1. Define a simple ESB project: RS > Synch Routing Rule > File Adapter. 2. Perform a transformation in the routing service The only unmapped element in the target XML file is the InstanceId field element. 3. Perform the following steps to get the instance ID: a. Go to Design View. b. Select Advanced Functions in the Component Palette. c. Select xpath-expression and drag it to the middle column. d. Double-click the function icon. e. Enter ehdr:getInstanceID() in the XPath Expression field. f. Click OK. 4. Click Yes when prompted with a warning. 5. Map the function to the InstanceID element and save the project. 6. Return to the routing service where the XSL transformation activity is defined. 7. Double-click the routing service. 8. Expand the Properties section and add the following property: EnableAccessBusinessEvent=true 9. Save and deploy the project. The instance ID function should now work.
