Are your services loosely coupled?
Web Service technology has been a popular choice for the integration of enterprise applications for several years. While most software architects would agree that loose coupling between applications is one of the most important goals of enterprise integration, the way Web services are used in practice very often leads to a tight coupling. This results in brittle solutions that are hard and costly to change. In this session you'll learn how to use Web service technology to create loosely-coupled integration solutions.Spoilt for choice - How to pick the right Web service framework
The growing popularity of Web service technology has led to the release of a number of Web Service frameworks for the Java platform. As a result, developers are facing the challenge to pick the right one for their projects. This session compares four of the most popular Web service frameworks and discusses their features, strengths and weaknesses. Along the way, we'll gather a list of criteria that can be used to make a concious decision in your next project.

Java Web Frameworks - Overview of latest trends
Struts has been the most popular Java web framework for many years. But it also has a lot of shortcomings, which have annoyed developers increasingly. In the meantime, new generations of web frameworks have emerged, and today there is an incredible number of frameworks available. Some are just trying to make things a little better, others are following very different approaches. There's so much choice that it's really hard to get an overview. In this session, we'll have a look at some of the newer frameworks and compare their key features and characteristics.You can download the slides here.

Session: Real World Web Services
Web Services have become a very popular implementation technology and are widely used today. However, despite of ongoing efforts to improve development tools and interoperability between Web Service implementations, creating a Web Service application is generally not a simple task. Numerous aspects have to be considered, and a lot of experience is needed to make the right decisions. When and where should Web Services be used? How important is interoperability for my specific application? Which framework should we use and which is the right development approach? In addition, typical challenges IT staff are faced with are hardly documented or explained. These challenges include topics like WSDL versioning and selecting the right level and approach for securing Web service communication. In this session, you'll learn how these issues have been solved in real world applications.Session: Inside Apache Axis2
The internal SOAP processing engine is the core of the Axis2 framework. It provides a powerful extension mechanism, which can be used to plug arbitrary functionality into the engine. Compared to its predecessor Apache Axis 1.x, both the engine and its extension mechanism were greatly improved. Many concepts of Axis 1.x can still be found in Axis2, but at the same time new features were added and new concepts like phases and modules were introduced. When developing Web Service applications with Axis2, it is essential to understand how the internal message processing works and how it can be controlled, extended or changed. This session provides helpful expert knowledge, which will enable developers to efficiently use Axis2 in their projects and to leverage its powerful features. Attendees will learn, how messages flow through the Axis2 engine, what flows, phases and handlers are all about and how to change the behaviour of the engine.Session: Invoking Web Services from AJAX applications using JSON
The main focus of Web Services is to facilitate interoperability in heterogeneous environments. In most cases, this means that either server-side components or rich client applications fulfill the role of the service consumers. With the success and widespread use of AJAX, a third scenario has become quite popular: invoking web services asynchronously from within the browser. How can this be done? One obvious way is to write some JavaScript code to build SOAP messages, which are then sent to the service. There are a few JavaScript libraries available, which make this task a little easier. But still, this approach is not very convenient. Very often, a much better way is not to send XML messages, but to use JSON for the communication with Web services. For this approach, a Web Service framework is needed on the server side, which provides good support for alternative message formats. One of these frameworks is Apache Axis2. This session demonstrates, how services hosted by Axis2 can be invoked from AJAX frontends using JSON messages.

Workshop: Hands-On Apache Axis2
Apache Axis2 is the successor of the very popular Axis 1.x framework and enables developers to implement modern Web services applications. In this 1-day workshop, you'll learn all the fundamentals needed to start using Axis2 in your own projects. In practical exercices, we'll create a Web servive from POJOs, and also use the code generator to implement a Web service application using the Contract First approach. Bring your own Windows laptop, and all your questions.Session: Inside Apache Axis2
To be able to get most out of the Axis2 framework, it's crucial to have a good understanding of how it works internally and how message flow through the core of the processing engine. This session explans the architecture of Axis2 as well as all it's new and improved concepts, like flows, phases, handlers and modules.Session: Best practices for developing interoperable Web service applications
Web services are a rather new technology for many developers. However, it's been around since more than six years now. Over the past years, a number of best practices have been developed that guideline the use of Web services. In this session, the most important expert tips will be introduced. Following these guidelines, developers will be able to successfully implement Web service applications faster, sailing around most typical interoperability traps.

Axis2 provides up-to-date support for all Web service standards and specifications that are important for today's applications. Some of this support is already included in the framework's distribution (WS-Policy, WS-Addresiing), in other cases additional extension modules need to be downloaded and deployed (WS-Security, WS-ReliableMessaging). To be able to meet typical requirements of modern Web service applications, it's crucial for developers to understand what these technologies are all about and how to use there implementations with Axis2. This session serves as an introduction into this topic.

Best practices for interoperable web service applications
One of the key features of web service technology is the ability to integrate heterogeneous platforms and systems. However, it doesn't seem to be that simple to achieve the promised interoperability in practice.Very frequently developers get stuck with interoperability issues of their web service application. In many cases, the reason for these problems can be found in the development approach they used.
In this talk, we'll have a look at the "Contract First" approach and how it leads developers to truly interoperable web service applications, sailing around many hidden traps. You will learn how this approach can be used when using Java to develop your applications and which tools can be helpful along the way.

Congress: Web Services and Security, 24 Nov 2005 in Darmstadt, Germany
Fundamentals of secure Web service applications
The security requirements of many web service applications are similar to those of "normal" applications. Particularly, communication and data exchange should be private and it should be possible verify the identity of communication partners if necessary. There are different ways to accomplish these requirements when implementing web services. This presentation introduces all the neccessary fundamentals for making the right choices in your own projects.Topics: transport security vs. message security, SSL, WS-Security, further WS-* specifications (WS-Policy, WS-Trust, WS-Reliable Messaging), WS-Security in practice, interoperability between Java & .NET
