Web Services Q&A - July 2002
It is very simple to make PowerBuilder applications consume Web Services. PowerBuilder 9.0 provides wizards for developers to specify a WSDL file, its services and ports, and then PowerBuilder will generate the proxy in PowerScript for your Web Services and build PowerBuilder applications that consume the Web Service(s). If you use PowerBuilder?s JSP client, PowerBuilder will generate custom tags for your JSP to access Web Services. The PowerBuilder 9.0 Beta is available on Sybase.com at http://www.sybase.com/betapb90program.
It requires a third-party tool from Microsoft and some manual work to expose a COM object to Web Services.
A possible approach is to wrap your stored procedure as a PowerBuilder NVO, deploy it on EAServer, and expose it as a Web Service(s).
4. We want to develop web applications under the .NET framework. We currently have client/server PowerBuilder applications. Can they be migrated into a .NET type of environment or would it be best to redevelop then using the Microsoft family of products?
Sybase is committed to delivering PowerBuilder DataWindow.NET and DataStore.NET, and making PowerBuilder NVO components available on the .NET framework. Developers will be able to continue their high productivity in building PowerBuilder components and deploying to the .NET framework.
A summary on ebXML comes directly from ebXML.org - ebXML enables enterprises of any size, in any location to meet and conduct business through the exchange of XML-based messages.
