Overview of this book

WSO2 Enterprise Integrator brings together the most powerful servers provided by the WSO2 company for your SOA infrastructure. As an Enterprise Service Bus (ESB), WSO2 Enterprise Integrator provides greater flexibility and agility to meet growing enterprise demands, whereas, as a Data Services Server (DSS), it provides an easy-to-use platform for integrating data stores, creating composite views across different data sources, and hosting data services. Using real-world scenarios, this book helps you build a solid foundation in developing enterprise applications with powerful data integration capabilities using the WSO2 servers. The book gets you started by brushing up your knowledge about SOA architecture and how it can be implemented through WSO2. It will help build your expertise with the core concepts of ESB such as building proxies, sequences, endpoints, and how to work with these in WSO2. Going further, you will also get well-acquainted with DSS data service concepts such as configuring data services, tasks, events, testing, and much more. The book will also cover API management techniques. Along with ESB and DSS, you will also learn about business process servers, the rules server and other components that together provide the control and robustness your enterprise applications will need. With practical use cases, the book covers typical daily scenarios you will come across while using these servers to give you hands-on experience.

Summary

In this chapter, we learned how to work with the payload of messages to adapt it to our requirements. We saw the use of different tools in relation to the target that we need to cover, because if we want to create a new payload, we'll use the PayloadFactory mediator. Meanwhile, if we want to change small things in the payload, we will use the Enrich mediator instead.

As we saw in the chapter, we can easily modify the content of the payload using the PayloadFactory mediator or the Enrich mediator without needing to have advanced knowledge of transformation languages such as XSLT or XQuery. However, these languages will be useful when we have complex transformations, and we want to use the XSLT/FastXSLT or XQuery mediator.

In the next chapter, we will see the different techniques and tools that we have for adding conditional routing to our services. This will give us...
