  3. Agenda • PowerBuilder Roadmap • Deploying PowerBuilder .NVOs as .NET Assemblies • Deploying PowerBuilder NVOs as .NET Web Services

  4. PowerBuilder Roadmap • Version 11 released in June 2007 • 11.1 Maintenance Release in November 2007 • Delivers on third-phase of PowerBuilder’s .NET initiative

  5. 2008 PowerBuilder 11.2 2008 PowerBuilder 11.5 2009 PowerBuilder 12 • AJAX support for Web Forms Applications • EAServer .NET Client Support • Enhancement requests • Core .NET enhancements • Native DataWindow updates • Updated database support • Enhancement requests • .NET in IDE • WPF/WCF support at design and run-time • Fully managed code at deployment • PowerScript Language Enhancements Language Independence Application Connectivity Multiple Platform Support Power And Performance

  6. Deploying PowerBuilder NVOs as .NET Assemblies

  7. What are .NET Assemblies? • In the Microsoft .NET framework, an assembly is a partially compiled code library for use in deployment, versioning and security • .NET assemblies contain code in the Common Intermediate Language (CIL), which is generated from .NET languages • The CIL is then compiled into machine language at runtime by the Common Language Runtime (CLR) just-in-time compiler

  8. Deploying NVOs as .NET Assemblies • .NET Assembly Target type • PowerScript data types automatically mapped to C# • Integrated .NET debugger support

  9.

  10. Deployment Considerations • The PowerBuilder .NET Runtime Assemblies need to be deployed to the client PC (You can use the PowerBuilder Runtime Packager)

  11. Deploying PowerBuilder NVOs as .NET Assemblies - Demonstration

  12. Deploying PowerBuilder NVOs as .NET Web Services

  13. What are Web Services? • A collection of operations that can be described, published, located, and accessed over a network using standardized XML messaging • Proposed to World Wide Web Consortium (W3C) in Mar 2001 • http://www.w3c.org • Web Services utilize XML making them both platform and language independent • XML gives us a mechanism for making cross-platform and/or cross-language communications

  14. Web Services Components • The primary components that make up Web Services are: • WSDL – Web Services Description Language • Used to describe Web services • SOAP – Simple Object Access Protocol • Used for sending and receiving messages from Web services

  15. Deploying NVOs as .NET Web Services • .NET Web Services Target type • Stateless design • Public methods mapped to Web Service messages • Selectively exclude additional methods from deployment • Method aliases permitted (e.g., to account for overloading) • Design time validation available • PowerScript data types mapped to XML schema types • Integrated .NET debugger support

  16. Sybase.PowerBuilder.Web.DLL Sybase.PowerBuilder.Common.DLL Sybase.PowerBuilder.Interop.DLL Sybase.PowerBuilder.Core.DLL Architecture:.NET Web Services Compiles to NVO ASP.NETWeb Service PBLs with NVOs DataWindow .NET PBDWM.DLL PBSHR.DLL DB Drivers Unmanaged DLLs (without PBVM) PB System Library for .NET

  17. Deployment Considerations • The PowerBuilder .NET Runtime Assemblies need to be deployed to the Web Server (You can use the PowerBuilder Runtime Packager) • The IIS Web Server needs to be configured to use ASP .NET 2.0 • Refer to the Configuring ASP .NET for a .NET Project section in the Deploying Applications and Components to .NET manual (Compiled HTML Help File)
