The Java platform provides a top-to-bottom, end-to-end solution for a Web services architecture. In this article, Eric Armstrong provides an overview of Sun's new Web services APIs. These latest releases provide an impressive array of performance and functionality capabilities.

The following sections provide an overview of Web services, and how they are implemented in WebLogic Server:

This QuickStart describes how to use a Web service that provides results for simple arithmetic. This Web service is described in the full .NET Framework QuickStart "Write a Simple XML Web service," for which this QuickStart provides a client application as shown in the following screen shot. To read the Web service QuickStart, click here.

Creating a Web service in .NET is easy, and so is a call to a COM object. See how to put them together when the COM object uses a single-threaded apartment model.

The SOAP RPC Technology Previewis an update to Forte for Java Enterprise Edition 3.0 that supports the creation, assembly, and deployment of SOAP RPC Web Services using the Apache SOAP runtime.

This how to describes the steps to visually develop a J2EE web service based on a Java class, using the UML Java Class diagrammer. You test the service by running it in the embedded OC4J application server and generate a client stub to call it, all directly from the Java Class diagram.

This section describes methods for securing your XML Web services. If you haven't already read the Security section of this tutorial, take the time to do so now before continuing in this topic.

Compressing text is a procedure that can reduce the size of content representation up to 80%. This means that compressed text can be stored using 80% less space than uncompressed text. It also means that the content needs less time to be transferred over a network, which translates into higher performance for client-server applications that communicate with text, like XML Web services.

We present a platform for Web services. Web services are implemented in a special XML programming language1 called XL [1, 2]. A Web service receives an XML message as input and returns an XML message as output. The platform supports a number of features that are particularly useful to implement Web services; e.g., logging, timetables, conversations, work ow management, automatic transactions, secu- rity.

In this tutorial, you will build a sample customer application that invokes Web services as user defined functions. This tutorial demonstrates how Web services calls can be easily combined with SQL to create DB2 applications on the Windows platform. [pdf]

Web services in our context means simply that we want our monitoring services to be accessible from Internet using its protocols. Although this ,in some cases, may require only writing a simple CGI-script or a PHP page backed by a Mysql database, in general we need the possibility to grant users the full access to powerful computing facilities , to online instruments control, etc

The Java Web Services Developers Pack (WSDP) gives Java developers a suite of Application Programming Interfaces (APIs) for Web services now that will be built-in to Java 2 Platform, Enterprise Edition (J2EE) 1.4 when it releases.

In this introduction, we begin with a programmatic definition of Web services, then quickly move on to show a simple Java class that calls and executes a Web service. All of our examples will be in Java. We've created our examples using Systinet WASP Server for Java, 4.5 (details on how to access and download this software is in the Installing software chapter).

Web service technologies are fundamentally changing the software industry, making the role of enterprise IT organizations more strategic, and recasting the software vendor-consumer relationship. Web services are also being hailed by CEOs, CIOs, and CTOs as the next-generation vehicle for driving top line growth and controlling bottom lines.

As the title suggests, the Web Services Workshop last week (April 11th and 12th) in San Jose, California was quite a grand gathering of some very intelligent minds, all focused on the future of this new emerging paradigm that we call "Web services."

The Oracle Application Server Web Services Tutorials are an ongoing set of hands-on tutorials designed to help developers understand the mechanics and issues behind building Web services. Starting from simple Java web services, developers move to J2EE components like Enterprise Java Beans through to database stored procedures.

One of the earliest promises of XML was the separation of content from format. Unlike HTML and most proprietary document formats, what you wrote would be completely separated from the appearance of your finished document. Furthermore, XML could be used to describe content—to give information about what you were writing.

The purpose of the WebService behavior is to provide a simple way of using and leveraging SOAP, without requiring expert knowledge of its implementation. The WebService behavior supports the use of a wide variety of data types, including intrinsic SOAP data types, arrays, and Extensible Markup Language (XML) data.

This section will walk you through the basics of sending a SOAP message using the JAXM API. At the end of this chapter, you will know how to do the following:

Here in part two, we will examine a real application built with the Microsoft MapPoint .NET XML Web service to get a first hand look and an appreciation of the simplicity this new generation of location technologies brings to your applications.
