PowerBuilder 9 [PDF ebook] 
Internet and Distributed Application Development

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