CXF Restful Tutorial
CXF Restful Tutorial explains step by step details of Creating / Developing Java rest Web services using Apache CXF, Spring and Eclipse
JAX-RS is Java API for RESTful Webservices which is very rely upon Representational State Transfer model, you can view JAX-RS specification
JAX-RS uses annotations for simplifying the development efforts.
Now a days more & more deployment is going based on restful services compare to WSDL Webservices, due to the weights towards the simplicity of configuration
You can see the below example, which is demonstrating How to create a Restful service using CXF

CXF Restful Tutorial
I am creating a sample restful service project that pass Student object and return with some changes on that object. The service is using simple POJO (Plain Old Java Object) bean.
Firstly create a Dynamic Web Project (File->New->Dynamic Web Project) named "CXFRestfulTutorial" according to following screenshot
Create a Student Object
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "Student")
public class Student {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Here @XmlRootElement(name = "Student"), is a JAXB convension specifies that Student is XML document.
If you are specifies that @Produces("application/json") then Jettison library converts the JAXB to json text as response
