  17. J2EE vs .NET • JDBC vs. ADO • JFC vs. Windows Forms (native) • Microsoft Intermediate Language (bytecode) • Common Language Runtime (CLR) (JRE) • JCA ~ COM TI Legacy integration

  18. J2EE vs .NET • JRE CLR • JSP ASP • EJB .NET Managed Components • JDBC ADO • SOAP/WSD/UDDI

  19. J2EE vs .NET • Multiple languages - common library - single platforms • Unified programming model and high productivity IDE • Separation of app and presentation • XML support
