Question

I have some problem when unmarshaling a .xml at a web service using JAXB.

This is the .xml file being sent from some client to the web service.

<?xml version="1.0" encoding="UTF-8"?>
<PERSON xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="file:/D:/MyWorkSpace/JAVA%20WEB%20Services%20DEVELOPER/XML%20Workspace/Persons.xsd">
    <NAME>Michael</NAME>
    <AGE>12</AGE>
    <ADRESS>
        <STREET>Somewhere in Spain</STREET>
        <ZIP>47015</ZIP>
    </ADRESS>
    <HOBY indoorHoby="true"/>
</PERSON>

This is the method that does the unmarshaling

    @POST
    @Path("/XMLArrivalBeacon")
    @Consumes(MediaType.APPLICATION_XML)
    public Response methodI(String content) {
        System.out.print(content);
        try {
            //Unmarshaling            
            JAXBContext context = JAXBContext.newInstance(Person.class);
            Unmarshaller unmarshaller = context.createUnmarshaller();
            //Unmarshal the String
            Person person = (Person) unmarshaller.unmarshal(new StreamSource(new StringReader(content)));
            //Checking that the values were recieved ok
            System.out.print(person.getName());
            return Response.ok("XML recieved from client!!!").build();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

Here is the person class annotated with the JAXB annotations(Was automatically generated from the Schema)

}

And this is the exception i get

SEVERE: javax.xml.bind.UnmarshalException: unexpected element (uri:””,
local:”PERSON”). Expected elements are <{}Person> at
com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallingContext.handleEvent(UnmarshallingContext.java:662)

com.sun.xml.bind.v2.runtime.unmarshaller.Loader.reportError(Loader.java:258)
at
com.sun.xml.bind.v2.runtime.unmarshaller.Loader.reportError(Loader.java:253)

Any idea how can i fix it?

Answer 1

Your xml does not match your schema. xml element names are case sensitive. “PERSON” and “Person” are not the same element.
