You can rewire an Enterprise JavaBeans (EJB) reference to a Service Component Architecture (SCA) reference that provides the same named operations. The rewiring does not require a change to existing code.
Identify the Java Platform, Enterprise Edition (Java EE) application that contains business logic in EJB or web modules to enable in the SCA environment. A Java EE application is also called an enterprise application or enterprise archive (EAR) file.
Identify the SCA components and services to replace the EJB references in EJB and web modules.
The SCA programming model supports Java EE integration. You can rewire EJB references to SCA references without changing existing code that uses the EJB reference. Thus, you can use the SCA programming model without changing the implementation code.
The EJB references are rewired to SCA references enabling Java EE modules to use SCA features without changing its implementation.
Deploy the enterprise application and the SCA composite that uses the application as composition units of the same business-level application. You can use the administrative console or wsadmin commands to create the business-level application and add the enterprise application and the SCA composite as composition units.
