Developing RESTful Services using Apache CXFIntroduction. As you already know there are two ways of developing a web service. Simple Object Access Protocol SOAPRepresentational State Transfer RESTBefore jumping on how to create a REST based web service using Apache CXF we shall see what is REST. REST is not a technology and certainly is not a standard of some kind. It is merely an architectural style that chalks down how to write a web service in a certain way. This style was defined by a certain Roy Fielding ring bells HTTP in 2. Principal protagonist of a REST architecture is a Resource which can be uniquely identified by an Uniform Resource Identifier or URI. State of a resource at any given point of time is represented by a document and is called Representation of resource. The client can update the state of resource by transferring the representation along with the request. The new representation is now returned to client along with the response. Carmelo Elorduy I Ching Pdf. The representation contains the information in formats like html, xml, JSON etc that is accepted by the resource. The resource which adheres to rules of REST architecture is called a RESTfull resource and web service that adheres to this rule are called RESTfull web service. Create a project to contain your web service. I generally do my web development in struts. Strut. 2 starter archetype to create my web project. To use CXF in my project I add following dependencies to my POMlt dependency. Id org. apache. Id. Id cxf rt frontend jaxwslt artifact. Id. lt version cxf. Id org. apache. Id. Id cxf rt transports httplt artifact. Id. lt version cxf. Id org. apache. Id. Id cxf rt transports http jettylt artifact. Id. lt version cxf. The non maven users can find the details of dependencies to be added in following linkhttp cxf. The CXF can be directly downloaded from herehttp cxf. How to Create a CXF RESTfull web service Suppose you want to create a RESTfull web service using CXF for managing books in your personal bookshelf. You would typically want to perform following operations on the bookshelf.

Id like a way to break this input up, specifically. Secure File Transfer Protocol or SFTP uses the SSH secure shell protocol to provides file access, file transfer, and file management functionalities over any reliable.

VO with the request or response it needs to serialized into either XML or JSON streams. The serialization needs to be done using one of the data binding components. CXF uses JAXB for default data binding component. Ja. XB uses Xml. Root. Element annotation to map the data object to the xml. You can see the use of Xml. Root. Element annotation in code above. Create the service implementation class to accept request and generate response. Through The Fire Sebastian Telfair Youtube on this page. Let us see how a CXF Rest. Full webservice looks. We will create a Book. Service class which will perform add,update,delete and get operations on Book. Self. Book. Service Classpackage com. Hash. DB. import com. Book. VO. import org.

Book and add. Book. They are service methods for getting and adding a book. Rest of the methods for update delete etc can be written in same way. Now lets see what the various annotations and method call means. POST This indicates that service receives only POST request. Path This is the path of webservice. So the webservice can be invoked using following Url lt baseurl bookservicegetbookname for fetching, lt baseurl bookserviceaddbook for adding. Produces Indicates the MIME type of response generated. In our case it is both applicationxml and applicationjson. Consumes Indicates the MIME type of request which this service can consume. Registering your webservice with CXF container. One cool thing with CXF is that it uses a spring based configuration for registering its webservice endpoints so let us create a beans. WEB INF and configure the CXF in web. For this first we need to wire the beans. Config. Locationlt param name. WEB INFbeans. xml,WEB INFapplication. Context. xmllt param value. Secondly load the register the CXFServlet in web.
