A customer demands access to your Service Composite Architecture (SCA) application.
However keeping with the customer’s company standards, the interface must be EJB 3.0.
Which solution meets the needs of the customer while requiring the least amount of time, effort, and architectural change for you?
A. Create a small EJB 3.0 application that interfaces directly with your SCA application. This approach hides the web service interface from your customer while adding the smallest amount of overhead in the process
B. Create an EJB 3.0 interface using Oracle Service Bus, which, in turn, invokes the SCA application through its native web service interface. This approach hides the web service Interface from your customer while adding the smallest amount of overhead in the process.
C. Use the Mediator component to provide an EJB 3.0 interface in addition to the existing web service interface. This approach adds the least amount of overhead to each call.
