Chapter 7. The Web Request Handling Layer

The request handling layer is the glue that binds the HTTP client to the services provided by your application. It is the interpretation of requests and the transfer of data that is the realm of this layer. Our focus will be on the data that is consumed and submitted by Ext JS 4 clients. This data is in JSON format and we will hence discuss JSON parsing and generation using the Java API for JSON Processing. It is important to note, however, that any type of data can be exposed by an appropriate request handling implementation. It is just as easy to implement an RMI or RESTful interface, if required.
