Need for Comparison :

In SAP NetWeaver stack application platform is provided by the Web Application Server. All the components of the SAP NetWeaver stack run on WAS. Similarly Oracle Application Server is the application platform for Oracle’s technology stack.So we should know the similarities and differences between the two.

Open System Architecture :

WAS :

  • J2EE certified
  • Web Services support.
  • Platform independent
  • Highly scalable and reliable

Oracle Appliation Server :

  • J2EE certified.Its development is focused as a single source-code model
  • Web Services Web Services support
  • The features are consistent across platforms for implementations, hence companies can migrate to various hardware vendors and operating systems while leveraging investments in Oracle Technology , hence platform independent
  • Highly scalable and reliable

    Application Development
    9 Ease of Development Application Development is very easy .SAP NetWeaver Developer Studio is Eclipse based IDE,hence development is facilitated. This provides different perspectives for different types of projects which can be deployed on J2EE Engine. Easy Application Development. Uses Oracle JDeveloper as a part of Oracle Developer Suite , which can create Java applications that are deployed on an Oracle Application Server Platform. Provides various wizards to create Java and J2EE objects and project types.e.g.

    • A Data Form wizard.
    • A beans wizard for creating Java Beans and BeanInfo classes
    • A deployement wizard providing one-click deployement of J2EE applications to OC4J instances by caching them in a pool and checking the connections in or out as per requirement.
