Mule ESB is a lightweight Java-based enterprise service bus (ESB) and integration platform that allows developers to connect applications together quickly and easily, enabling them to efficiently exchange data. You can therefore use Mule ESB to allow different applications to communicate with each other via a transit system to carry data between applications within your enterprise or across the Internet. It is also useful if you use more than one type of communication protocol while integrating three or more applications/services. "Mule ESB Cookbook" takes readers through the practical approach of Mule ESB 3.3. This book solves numerous issues faced by developers working on Mule ESB in real time and provides use cases on how to integrate Mule with other technologies. It also focuses on development and delivery using Mule ESB through integrating, migrating, and upgrading advanced technological tools. This book gives the reader a strong overview of the Mule framework using practical and easy-to-follow examples. It has three sections: problems, approaches, and solutions. The key aim of this book is to show you how to allow different applications to communicate with each other by creating a transit system to carry data between applications within your enterprise or across the Internet. Mule ESB enables easy integration of existing systems, regardless of the different technologies that the applications use, including JMS, Web Services, JDBC, HTTP, and more. "Mule ESB Cookbook" will teach you everything you need to know to communicate between applications that are built on different platforms, as well as how to migrate them in your application across multiple platforms or on the cloud.
