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. Now we'll explore the technologies that make it easier to use
Web services that have already been deployed.
What Is WSDL?
WSDL is an XML-based language used to define Web services and describe how to
access them. Fortunately, we don't need to learn all the details because
there are tools or implementations like Axis that generate WSDL for us. This
article provides you with just enough information on WSDL to u... (more)
WAP stands for Wireless Application Protocol and is based on Wireless Markup
Language (WML), which is closely related to Hypertext Markup Language (HTML).
WAP enables you to quickly and easily deliver information and services to
mobile users. It's independent from any other mobile or network standard and
is compatible with all popular mobile communication networks.
WAP is a communications... (more)
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)
I'm sure many of you have experienced the same problems within your company
as I've experienced at my work these past few months.
We have a single database server serving every part of our information
processing community within our company, from transaction to batch processing
to analytical processing. We have a huge amount of complex data and/or an
unpredictable number of queries that a... (more)
An enterprise portal is the converged "hub" of multiple, complementary
information management solutions, including document and content management,
information search and retrieval, knowledge management, team collaboration,
workflow, and business intelligence.
Using PowerBuilder with Sybase Enterprise Portal
Sybase Enterprise Portal is built around Sybase Enterprise Application
Server. A ... (more)
