CXF REST Exception Handling explains about step by step details of Exception Handling In REST services using Apache CXF with Eclipse IDE

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.

Apache CXF provides in built exception handling mechanism for both REST & SOAP based services, By using this you can handle exceptions very easily without any additional efforts.

You can see the below example, which is demonstrating How to handle an exception in a REST service using CXF

Note

CXF REST Exception Handling Example

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

CXF REST Exception Handling CXF REST Exception Handling

Create a Student Object

package com.student;

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 convention 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
