Oracle 9iAS includes Oracle Report Server, Forms Server, Oracle Portal, Oracle Wireless (previously named Portal to Go) and other services, including in latest versions OC4J, the J2EE container licensed by Oracle from Orion. Until version 1.0.2.2.1 OC4J was an independent component of iAS, but in latest versions is included into Oracle9iAS. But, al least, is one more component included in all services iAS provides.
At first version, Oracle used Database as Java container, by providing a Oracle 8i (8.1.7) database with a embebed JVM (called Aurora). But the results were not succesful, and Oracle licensed Orion J2EE container.
