Exception Handling Using PowerBuilder, EAServer, and JavaServer Pages Basic Techniques and Pitfalls PowerBuilder's Try-Catch-Finally exception handling mechanism brings a great deal of power and versatility to application and component development. It's important to be able to manage and handle exceptions thrown by service components, particularly when you are deploying to a Web environment. When you develop with PowerBuilder 9's JSP targets, you need to know how to throw exceptions from PowerBuilder components and how to catch and handle the exceptions within your JSP target. This article examines the techniques you can use and the challenges you will face in adding robust exception handling to your JSP Web application. Try-Catch-Finally in PowerBuilder WHY WE USE TRY-CATCH-FINALLY The Try-Catch-Finally method of exception handling was introduced in PowerBuilder 8. ... (more)

PFC Quickstart

PowerBuilder includes a powerful set of foundation classes to speed development. These classes are collectively known as the PowerBuilder Foundation Classes, or PFC. In Part 1 (Vol. 11, issue 9) I provided an introduction to PFC and demonstrated how to use it. Part 2 outlines the more recent changes and additions to PFC. PFC Quickstart This section contains some scripts that you can paste into your PFE objects to get a jump start on PFC programming.

PowerBuilder Foundation Classes

PowerBuilder includes a powerful set of foundation classes to speed development. These classes are collectively known as the PowerBuilder Foundation Classes, or PFC. Part 1 of this article provides an introduction to PFC and shows how to use it. For the experienced PFC developer, I'll outline the more recent changes and additions to PFC in Part 2. This article is not intended as a complete professional reference for PFC - that could be (and is) the subject of an entire book on its own. Nor is it intended as a tutorial, although there are code samples to show you how to use some ... (more)

PowerBuilder does JSP!

PowerBuilder 9 will introduce faithful PB developers to the ability to build and use JavaServer Pages (JSPs) in their PowerBuilder Web applications. This is a giant step forward in Sybase's continuing march toward industry-leading openness. All of PowerBuilder's capabilities, including the graphical development environment, the system tree, powerful SCC integration, rich Web Targets and object models, wizards for rapid development, and integrated EAServer development, can now be applied to JSP Web Target development. Why JSP? JavaServer Pages are part of the J2EE 1.2 Specification... (more)

Silent...but Effective

As of Sybase's EAServer 4.0, OEM developers and IT organizations can take advantage of two new installation features that allow them to create and deploy applications with an embedded installation of EAServer. EAServer 4.0 includes features that improve the ability of OEM vendors and IT departments to create and deploy applications that include EAServer. Through EAServer version 3.6.1, end users needed to install EAServer separately from the application using the standard dialog-driven setup routine. Developers deployed their components and applications using Jaguar Manager to ins... (more)
