Question

I have xsd and xml file. first I have generated Java classes from xsd file ,that part has done and now I have to feed data into objects using xml ? I am using below code , but this is throwing JAXBException.

    try {

    File file = new File("D:\\file.xml");
    JAXBContext jaxbContext = JAXBContext.newInstance("com.jaxb.generated");

    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    Employee empObj = (Employee) jaxbUnmarshaller.unmarshal(file);
    System.out.println(empObj.getName());

  } catch (JAXBException e) {
    e.printStackTrace();
  }

and here is my xml file which contains two classes :

   <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
     <Employee>
       <name>John</name>            
       <salary>5000</salary>
    </Employee>
    <Customer>
       <name>Smith</name>
    </Customer>

could somebody help me ?

Answer 1

The XML document in your question is invalid. XML documents need to have a single root element. The first step would be to ensure that your XML document is valid against the XML schema you generated the classes from.
