Part Number A86030-01
Using JDeveloper to Build Oracle XML Applications, 4 of 11
The Business Components for Java (BC4J) framework in JDeveloper 3.2 uses XML to define the metadata that represents the declarative settings and features of the objects. Custom or complex business logic can be implemented in Java.
The business components for Java framework that ships with JDeveloper uses XML to store metadata about its application components. Important information is now stored in a structured document rather than in Java source code. This makes the application easier to understand and customize.
The application is now customizable without having access to the source code.
Figure 14-1 shows how BC4J is used with XSQL servlet to generate XML documents.
Business rules can be changed on site without needing access to the underlying component source code.
