We aren't a news magazine, and we don't cover current events except as they relate to our industry, so I had to think long and hard about what to say in this edition. Nevertheless, I decided that at least in my editorial, we would remember September 11th.
Grid computing makes it possible to dynamically share and coordinate dispersed, heterogeneous computing resources. Flexibility and ubiquity are essential characteristics of Web services technologies such as WSDL (Web Services Description Language), SOAP (Simple Object Access Protocol),...
The current implementation of the World Wide Web and its supporting Internet infrastructure is predominantly geared toward information retrieval and display in a humanly readable form. Its data formats and protocols are neither intended nor very suitable for automated machine-machine i...
Many companies are in the initial planning and pilot stages with Web services initiatives and may not think they need to consider management solutions right now. They need to think again.
Exploring a business application published as a Web service in the UDDI registry or Web Services-Inspection (WS-Inspection) documents is a critical issue. A search for such an application should be effective in terms of time and uniform in terms of interfaces.
This month WSJ focuses on P2P architectures and grid computing, two topics that are gaining momentum in our industry. Over the past year or so I've read many excellent articles and books on these topics. However, getting a handle on what P2P and the grid are can be a challenge as imple...
I must admit that the subtitle I used here sounds a bit like an overused marketing cliché broadcast from a late-night commercial on television. Anyone seriously involved in enabling enterprise resources as SOAP-based services on the Web knows that the 'today' part is quite a stretch.
As a developer (or potential developer) of Web services, sooner or later you are going to wonder just how you might be able to reduce the interoperability issues you see. If you work with Apache Axis or Apache SOAP 2.x, you will see this problem when sending a java.lang.Hashtable to a ...
Field workforce management is an application segment responsible for scheduling resources working in the field, assigning work orders, dispatching work, and letting workers report from a mobile terminal. Among those using such systems are utilities, construction crews, maintenance orga...
It's banal but true. The network, or the Internet, has indeed become a computer. It's possible now to assemble an application from network-based components called Web services.
With the advent of J2EE 1.3, we've become familiar with the message-driven bean (MDB) as a key architecture component, and the use of asynchronous messaging as an aid to application scalability. But there are many more ways in which messaging can be used to build robust Java applicatio...
Enterprises are beginning to develop and deploy applications with Web services, a standards-based approach to achieving application interoperability. Web services technology is enabled by a set of standards that specify description, discovery, and invocation via the Internet.
Web services, XML, UDDI, SOAP, WSDL, .NET. Today it seems that anyone even thinking of investing in technology to solve a business problem is immediately overwhelmed by a cacophony of alphabet soup-like acronyms with the common promise of... well, just what isn't entirely clear. But 't...
The emergence of service-oriented architectures (SOAs) is an exciting development, providing a springboard for the advancement of flexible, dynamic distributed computing solutions. For those not familiar with SOAs, you can think of them as loosely coupled pieces of applications that ar...
