- Invoking Web Services using Apache Axis2 by Deepal Jayasinghe - [Clicks: 482]
How would you like to invoke a web service--blocking or non-blocking? Over a single transport or multiple? With or without exception-handling? Apache Axis2 gives the developer a wide set of options, as illustrated in this article by Deepal Jayasinghe.

The Apache Axis2 Web services framework builds on the new AXIOM XML document model for efficient SOAP message processing. Unlike conventional document models, AXIOM builds the document representation in memory only as it's being accessed. Learn why this on-demand construction is a great approach for SOAP processing, and how XOP/MTOM attachments, data binding, and performance fit into the picture.

The principle of "separation of concerns" is much repeated in SOA circles... so why are transactional integrity, security, and business logic so often intermingled in SOA implementations? In this article, Tieu Luu shows how to use Spring to separate out security concerns in an Axis-based web service.

Apache Axis2 is the successor to the Apache Axis SOAP project. It is a major improvement of the Web services core engine and aims to be the platform for the next generation of Web services and Service-Oriented Architecture (SOA). It is becoming increasingly popular by being a clean and extensible open source Web services platform. The architecture of Axis2 is highly flexible and supports much additional functionality such as reliable messaging and security.

When implementing Web services, there are two alternative development paths one can take: the code-first approach and the contract-first approach. This article drills down into the contract first approach in detail and shows how the Axis2 code generator can be used to generate code for the server side with the contract first approach.

Code Generation is an essential technique for developers working with SOAP, as web services' WSDL documents describe the services in machine-processable ways, which enables automated generation of classes to work with the service. In this article, Ajith Ranabahu looks at how Apache Axis2 provides flexibility for different code generation scenarios.

With the rise of Apache Axis and its latest successor, Axis2, developing Web services on Apache Geronimo has become easier and less cumbersome. Axis2 is an improvement over Axis, because a better architecture was implemented for Axis2, deployment was simplified, and Axis2 provides more data binding support. This article describes using a sample Web service and migrating a previously developed Web service in Axis to Axis2. The various changes and improvements in Axis2 over Axis are discussed as well as how this relates to deploying the newly migrated Axis2 Web service on the Geronimo application server.

Web services is positioned as the technology for integration. For architects and developers on Java/Java Enterprise Edition platforms, Apache Axis is a key open source means by which SOAP-based Web services can be enabled for service-providing components. Most common Web services implementations, in spite of all their strengths, still suffer from the unreliability of the HTTP protocol and Web environment. While WS-Reliability is emerging to be a strong reliability standard, solutions requiring guaranteed mechanisms need to rely on message-oriented middleware (MOM) technologies. Asynchronous store-forward MOM technologies such as MQSeries, MSMQ (Microsoft Message Queuing), and SonicMQ are proven ways to achieve reliable and guaranteed information exchange. This article describes a solution that combines MOM and Apache Axis to achieve both guaranteed delivery and standards-based Web services for your integration undertakings. Note: This article is based on Apache Axis 1.2. Axis 2 currently has not reached release 1.0.
