Question

I’m using JAX-RS Jersey and JAXB on my server code to implement services. I am sending xml as input to resource and in the resource i am converting xml to object using JAXBContext. My resource is working when the xml consist of one root element.
like

<employee>
<id>1</id>
</employee>

But when i provide multiple elements I am getting UnmarshalException.

<employee>
<id>1</id>
</employee>
<employee>
<id>2</id>
</employee>     

My resource look like this.

@POST
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.APPLICATION_XML)    
 public Response addEmp(@Context HttpServletRequest req)throws JAXBException,IOException{
        JAXBContext jaxb = JAXBContext.newInstance(Employee.class);
        Employee emps = (Employee)jaxb.createUnmarshaller().unmarshal(req.getInputStream());
        emplist.add(emps);
        return Response.ok().entity(success).build();

Answer 1

First of all, don’t use req.getInputStream(). Instead, specify your input stream as an argument of a function:

public Response addEmp(InputStream stream) {

Second, your input XML is not a valid document. XML has to have a root element. You can’t give a few elements in one input stream. Instead, use a JAXB wrapper.
