The Web Services Description Language (WSDL) makes it possible for automated code-generation tools, like PowerBuilder 9 with its Web services wizard, to simplify building clients for existing Web services. In my previous article "Axis" (PBDJ, Vol. 9, issue 8) we discussed the basic steps involved in implementing a Web service using Axis, EAServer, and PowerBuilder 8.

The EAServer Repository

EAServer includes a powerful API called the Interface Repository. In this article I'll create a small service component to clean this repository of unwanted files that might be created when you deploy PowerBuilder components. I'll show how to get all the packages associated with your server and read your component's special properties. With the Interface Repository you can do all the EASe... (more)
