The Oracle Forms Developer and Oracle Forms Server product set provides a rich applicationframework to build and deploy advanced business applications. With the tight integration theseproduct components have with the Oracle 8i Server products, the natural language of choice forapplication development is Oracle PL/SQL. Oracle PL/SQL is Oracle Corporation’s procedurallanguage extension to SQL, the standard data access language for object-relational databases.PL/SQL offers modern software engineering features such as data encapsulation, exception handlingand information hiding coupled with the absolute ease of access to data stored in Oracle 8i databaseservers through the SQL standard language. While Oracle PL/SQL is a powerful and productive development environment, it is sometimesnecessary to integrate Oracle Forms applications with other external application services andproviders. Usually these external applications are not written in Oracle PL/SQL so some form ofintegration capability is required. Traditionally, the interfaces and libraries exposed by externalapplications have usually been based on the C programming language. For these situations, theexisting Oracle Forms integration mechanism, ORA_FFI has proved more than sufficient With the ever-increasing momentum of the Java movement within the IT industry, manyapplications are now providing integration points in Java. Similarly, the number of standard Javalibraries for enterprise applications is continually growing.
