JAXB stands for Java architecture for XML pixia-club.info is used to convert XML to java object and java object to XML. JAXB defines an API for reading and writing. Take a look at how to marshal and unmarshal your Java objects and XML data with JAXB , a useful tool for generating XML schemas from.
It provides a comfortable way to retrieve and store data from XML documents to Java classes.
Instead I will focus on a little command line tool called xjc and show you how to generate your binding classes based on an existing XSD schema description. Implementing all binding classes for an existing XML interface can be a time consuming and tedious task.
But the good news is, you do not need to do it. If you have a XSD schema description, you can use the xjc binding compiler to create the required classes.
And even better, xjc is part of the JDK. So there is no need for external tools and you should always have it at hand if required. As the audience of this book is composed mainly of Java developers with little or no knowledge of WSDL basics, we will focus primarily on the bottom-up approach.
Restful Web Services in Spring
Designing top-down web services, on the other hand, will require you to integrate the basic web services notions provided with this chapter with a comprehensive awareness of the WSDL standard. The message content is extracted from the transport protocol and processed through the handler chain configured for the web service.
SOAP message handlers are used to intercept SOAP messages as they make their way from the client to the endpoint service and vice versa. These handlers intercept SOAP messages for both the request and response of the web service.
Marshalling and Unmarshalling in JAXB 2.0
Finally, the deserialized SOAP message reaches the actual web service implementation and the method is invoked.
Once the call is completed, the process is reversed.
The third and maybe unexpected class is the class ObjectFactory. It contains factory methods for each generated class or interface.
We had a look at xjc and used it to generated the required binding classes for an existing XSD schema definition. What do you think about xjc and the generated code?
Please leave me a comment and tell me about it. I think this tool generates very clean code and saves a lot of time. In most of the cases the generated code can be directly added to a project. But even if this is not the case, it is much faster to do some refactoring based on the generated code than doing everything myself. Is there a way to generate the classes automatically when schema gets changed like adding more complex-types etc.?
You could probably run it as part of your build process. But that would be up to you and your build tool.

Using xjc As you can see in the snippet below, xjc support lots of options. The output directory must already exist; the XJC binding compiler does not create one for you.
