The release-defining feature of PowerBuilder 11 is its ability to deploy existing applications as .NET Windows Forms and Web Forms applications and components of business logic, namely custom-class user objects (NVOs), as .NET assemblies and Web Services. Although PowerBuilder's adoption of the .NET Framework represents a great leap forward for application developers, the implications of converting a desktop, client/server application to an ASP.NET Web application are significant. Those of you who have been working with PowerBuilder 11 know this first hand just from the sometimes daunting list of unsupported features that can appear in the Output window after deploying a .NET target (Figure 1). The unsupported features list contains valuable information necessary for you to successfully bring your application's functionality into the .NET world; however, the organi... (more)

PowerBuilder and EAServer: Uniting the .NET and J2EE Communities

In PowerBuilder 11.2, .NET meets J2EE head-on with the capability to deploy .NET Windows Forms and Web Forms applications (as well as assemblies and Web Services) that access Enterprise JavaBeans (EJBs) in Sybase’s own EAServer. As you’ll see over the course of this article, integrating these “competing” technologies is quite straightforward and leverages mechanisms that have been available since PowerBuilder 7. The enabling technology for the .NET to J2EE functionality in PowerBuilder is the new client support introduced in EAServer 6.1. The EAServer .NET runtime includes three... (more)

PowerBuilder & Informix

In this article we'll discuss connectivity requirements, Informix-specific data type processing, and the use of Informix stored procedures within the PowerBuilder environment. PowerBuilder offers developers four specific connectivity options for IBM Informix databases: Third-party Open Database Connectivity (ODBC) drivers Third-party Java Database Connectivity (JDBC) drivers Third-party OLE-DB providers The "native" driver available in the PowerBuilder Enterprise version In this article we'll focus on the last option by discussing connectivity requirements, Informix-specific data...

EAServer Problem Analysis & Troubleshooting

Designing and implementing an n-tier or Internet application is a complex task, and issues resulting from errors in the runtime configuration or in the application code are practically inevitable. Problem analysis and troubleshooting are part art and part science. Therefore, although the techniques we'll discuss are often helpful, the sheer diversity of client and server environments precludes a single recipe for resolving all issues. Part 1 (PBDJ, Vol. 12, issue 2) focused on problems that involve PowerBuilder and that occur from the point of connectivity all the way through an E... (more)
