JAXB Unmarshalling not working. Expected elements are (none)

Question

I am trying to unmarshal an XML. This is what my XML looks like ``` 1 abc . . . ``` I am trying to get Id and Name under Obj123. However when I run my unmarshal command I get the following error. ``` An Error: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://tempuri.org/", local:"DeviceInventory2Response"). Expected elements are (none) ``` My code looks like this in the main class: ``` Obj123 myObj123 = (Obj123) unmarshaller.unmarshal(inputSource); ``` And my class for Obj123 looks like this: ``` package com.myProj.pkg; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlElementWrapper; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlType; @XmlRootElement(name="Obj123") public class Obj123 { private String…

Accepted Answer

JAXB implementations will try to match on the root element of the document (not on a child element). If you want to unmarshal to the middle of an XML document then you can parse the document with StAX advance the `XMLStreamReader` to the desired element and then unmarshal that.

UPDATE

now I am getting the following error. An Error: javax.xml.bind.UnmarshalException - with linked exception: [javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"Obj123"). Expected elements are (none)].

A `JAXBContext` only knows about the classes you tell it about. Instead of:

```
JAXBContext jaxbContext = JAXBContext.newInstance();
```

You need to do:

```
JAXBContext jaxbContext = JAXBContext.newInstance(Obj123.class);
```
