JAX-RS XML Example With JAXB Using Jersey

In this article i will give you an example on how a RESTful web service produces XML response using Jersey. Basically JAX-RS supports conversion of java objects into XML with the help of JAXB. As Jersey it self contains JAXB libraries we no need to worry about JAXB-Jersey integration stuff.

Steps Need to be Followed

  • Add ‘jersey-server.jar‘ to your Maven pom.xml which includes all JAXB supporting libraries into your class path
  • Annotate your service method with @Produces(MediaType.APPLICATION_XML)

Required Files

  • pom.xml
  • web.xml
  • Customer.java
  • RestfulXMLExample.java

     // WRITE DATABASE LOGIC TO RETRIEVE THE CUSTOMER RECORD WITH 'custID'
        
        Customer cust = new Customer();
        cust.setCustName("Java4s");
        cust.setCustCountry("USA");
        cust.setCustId(custId);
 
        return cust;        
     }
}
