Web services are the "new kids on the block" and as with all adolescent
technologies they are can be a little troublesome, take time to understand
and always testing you with something new. Given this, how does a developer
get started with Web services? And for those more experienced, how does the
developer speed up the developing, debugging, and deployment cycle?
In this paper we will hope to provide a jump-start to both these questions.
We will run through the basics of building Web services using the following
steps: Modeling Web services Building a Web service based on a EJB Publishing
an EJB Web service Deploying a Web service to an Oracle9i Application Server

Web services have moved beyond the experimental stage in many organizations
and are now becoming the foundation of numerous service-oriented
architectures. Thus, architects are concerned about best practices for
building, deploying, and maintaining a large-scale interoperable Web services
In one sense, Web services applications are like other applications. They
represent a code base developed by a team of engineers. This code base needs
to go through a methodological development life cycle, followed by testing
and quality assurance, before it is finally released.... (more)
If you've been working with integration technologies for any length of time,
you're well aware of the freight train of standards that has been careening
through the industry during the last five years. These standards,
particularly in the Web services space, are on the verge of doing to
proprietary integration servers what SQL and J2EE standards did to database
and middle-tier servers of days gone by.
Database veterans remember when Cullinet ruled the roost; many felt it had no
technical equal. SQL was an interesting idea, but not for real projects.
Likewise, long-time middlewar... (more)
