Oracle SOA Suite 10g to 11g Migration - Unable to register a service endpoint for a defined reference callback

Unable to register a service endpoint for a defined reference callback:

The invocation of the asynchronous web service from the composite has failed with the following error after migrating the code to Oracle SOA Suite 11g.

"Unable to register a service endpoint for a defined reference callback. Please ensure the WSDL and reference configuration are correct".

After a long struggle ,we have identified the issue .The issue was with the callback interface was wrongly configured with the value same us interface(no separate callback port is defined in the WSDL) during the migration in the composite.xml and the component files of the composite that invokes the asynchronous web service that doesn't have any callback defined.

Composite.xml with callback configured:



Component file with callback configured:




Asynchronous Web service with the callback port not defined:




Removing the callback interface configuration from the composite.xml and the component files of the composite resolved the issue.
