JAXB : 2 counts of IllegalAnnotationExceptions

You can see the below sample code to generate Java Object from given XML.It is working fine in my system.

customer.xml

<?xml version="1.0" encoding="UTF-8"?>
<company>
    <customer id="100">
        <age>25</age>
        <name>Ram</name>
        <Address>
            <city>Bangalore</city>
            <country>India</country>
        </Address>
        <Address>
            <city>Patna</city>
            <country>India</country>
        </Address>
    </customer>

    <customer id="200">
        <age>26</age>
        <name>Ashu</name>
        <Address>
            <city>Delhi</city>
            <country>India</country>
        </Address>
        <Address>
            <city>Madhubani</city>
            <country>India</country>
        </Address>
    </customer>
</company>

Outout:
Company [custList=[Customer [name=Ram, age=25, id=0, addressList=[Address [city=Bangalore, country=India], Address [city=Patna, country=India]]], Customer [name=Ashu, age=26, id=0, addressList=[Address [city=Delhi, country=India], Address [city=Madhubani, country=India]]]]]

For the @XmlAttribute/@XmlValue need to reference a Java type that maps to text in XML. issue you need to change your initialization of JAXBContext to the following:

JAXBContext jaxbContext = JAXBContext.newInstance(MyOrder.class, Order.class);

For the Class has two properties of the same name "order" issue, you need to change the definition of protected Order order; to private Order order;.

Also, you want to change the @XmlRootElement(name = "BXML") of your Order class to @XmlRootElement(name = "Order").

This is because the sub-elements of that class you are creating JAXBcontext instance ,doesn't have the same name as of the element names defined inside it.

Example:

@XmlType(name = "xyz", propOrder = { "a", "b", "c", "d" })
@XmlRootElement(name = "testClass")
public class TestClass
{

  @XmlElement(required = true)
  protected Status status;
  @XmlElement(required = true)
  protected String mno;
  @XmlElement(required = true)
}

In the above class you don't have "xyz" , but if you will put the property name that is not available JAXBContext instantiation throws IlligalAnnotationException.
