Producing a Web service
PowerBuilder
provides tools for developing custom class (nonvisual) user objects
and deploying them as EAServer components
and exposing them as Web services. You can deploy a component to
an EAServer host running on Windows
and UNIX operating systems. For more information, see Chapter 24, “Building an EAServer Component.”
For existing components on EAServer, you can generate a Java
bean for the component using EAServer Manager. Then, using EAServer’s Web Services Toolkit,
you can generate a WSDL file for the EAServer component, describing
your Web service and its location. You also create a client proxy
for the Web service, accessible to a client application. The client
proxy uses the WSDL document that describes your Web service/EAServer component. The client application
can then use the Web service. For more information, see the EAServer
Programmer’s Guide
and the EAServer Web Services
Toolkit User’s Guide
