Oracle Java Cloud Service (JCS) can be used for development, testing, user acceptance testing, staging and production applications. You can create dedicated and isolated Oracle WebLogic Server (WLS) 11g or 12c environments to run your entire cluster at scale.
Oracle E-Business Suite Release 12.2 uses a three-tier logical architecture. The technology stack for Release 12.2 comprises an application tier technology stack and a database tier technology stack. The Oracle E-Business Suite applications are tightly integrated with the various technology stack components.
The application tier technology stack in Oracle E-Business Suite Release 12.2 includes Oracle Fusion Middleware and Oracle WebLogic Server. WLS replaces the Oracle Containers for Java (OC4J) used with Oracle E-Business Suite Release 12.1.
We are sometimes asked if the Oracle WebLogic Server included with Java Cloud Service can be used with EBS Release 12.2 as an alternative to the embedded WLS that comes with EBS and is described above.
The answer is - no, you cannot. Such usage isn't supported because the Oracle Weblogic Server provided as part of EBS is a tightly integrated and customized component of the Oracle E-Business Suite Release 12.2 application tier technology stack. In addition, JCS does not provide the full application tier technology stack (including Oracle Forms and Reports) that EBS R12.2 (whether running on-premises or on Oracle Cloud) requires.
