Version 9 of PowerBuilder introduces many features designed specifically to blend the traditional strength of PowerBuilder as a rapid Client/Server application development tool with the new and emerging models for distributed application development. PowerBuilder developers need PowerBuilder-specific information on interacting with Java application servers, such as WebSphere, WebLogic, and Sybase's Enterprise Application Server (EAServer) and Web Service development. This book presents the new capabilities of PowerBuilder 9 along with the architecture and patterns required to create distributed systems in PowerBuilder.
