You need to put package-info.java in your generated jaxb package. Its content should be something like that

<pre><code>@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.org/StudentOperations/")
package generated.marsh;

After looking more, the root element has to be associated with a schema-namespace as Blaise is noting. Yet, I didnt have a package-info java. So without using the @XMLSchema annotation, I was able to correct this issue by using

<pre><code>@XmlRootElement (name="RetrieveMultipleSetsResponse", namespace = XMLCodeTable.NS1)
@XmlType(name = "ns0", namespace = XMLCodeTable.NS1)
@XmlAccessorType(XmlAccessType.NONE)
public class RetrieveMultipleSetsResponse {//...}

blocks|key|763356|text|这是对一个很小的用例的修复，但它每次都会让我抓狂。如果您使用的是Eclipse+Jaxb生成器，它会创建一个名为package-info的文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|763357|@javax.xml.bind.annotation.XmlSchema(namespace+=+"blah.xxx.com/em/feed/v2/CommonFeed")

This is a fix for a pretty niche use case but it gets me each time. If you are using the Eclipse Jaxb generator it creates a file called package-info. 

<pre><code>@javax.xml.bind.annotation.XmlSchema(namespace = "blah.xxx.com/em/feed/v2/CommonFeed")
package xxx.blah.mh.domain.pl3xx.startstop;
</code></pre>

If you delete this file it will allow a more generic xml to be parsed. Give it a try!

I had the same problem.. It helped me, I'm specify the same field names of my classes as the tag names in the xml file (the file comes from an external system).

For example:

My xml file:

<pre><code>&lt;Response&gt;
 &lt;ESList&gt;
 &lt;Item&gt;
 &lt;ID&gt;1&lt;/ID&gt;
 &lt;Name&gt;Some name 1&lt;/Name&gt;
 &lt;Code&gt;Some code&lt;/Code&gt;
 &lt;Url&gt;Some Url&lt;/Url&gt;
 &lt;RegionList&gt;
 &lt;Item&gt;
 &lt;ID&gt;2&lt;/ID&gt;
 &lt;Name&gt;Some name 2&lt;/Name&gt;
 &lt;/Item&gt;
 &lt;/RegionList&gt;
 &lt;/Item&gt;
 &lt;/ESList&gt;
&lt;/Response&gt;
</code></pre>

My Response class:

<pre><code>@XmlRootElement(name="Response")
@XmlAccessorType(XmlAccessType.FIELD)
public class Response {
 @XmlElement
 private ESList[] ESList = new ESList[1]; // as the tag name in the xml file..

 // getter and setter here
}
</code></pre>

My ESList class:

<pre><code>@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name="ESList")
public class ESList {
 @XmlElement
 private Item[] Item = new Item[1]; // as the tag name in the xml file..

 // getters and setters here
}
</code></pre>

My Item class:

<pre><code>@XmlRootElement(name="Item")
@XmlAccessorType(XmlAccessType.FIELD)
public class Item {
 @XmlElement
 private String ID; // as the tag name in the xml file..
 @XmlElement
 private String Name; // and so on...
 @XmlElement
 private String Code;
 @XmlElement
 private String Url;
 @XmlElement
 private RegionList[] RegionList = new RegionList[1];

 // getters and setters here
}
</code></pre>

My RegionList class:

<pre><code>@XmlRootElement(name="RegionList")
@XmlAccessorType(XmlAccessType.FIELD)
public class RegionList {
 Item[] Item = new Item[1];

 // getters and setters here
}
</code></pre>

My DemoUnmarshalling class:

<pre><code>public class DemoUnmarshalling {
 public static void main(String[] args) {
 try {
 File file = new File("...");

 JAXBContext jaxbContext = JAXBContext.newInstance(Response.class);
 Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
 jaxbUnmarshaller.setEventHandler(
 new ValidationEventHandler() {
 public boolean handleEvent(ValidationEvent event ) {
 throw new RuntimeException(event.getMessage(),
 event.getLinkedException());
 }
 }
 );

 Response response = (Response) jaxbUnmarshaller.unmarshal(file);

 ESList[] esList = response.getESList();
 Item[] item = esList[0].getItem();
 RegionList[] regionLists = item[0].getRegionList();
 Item[] regionListItem = regionLists[0].getItem();

 System.out.println(item[0].getID());
 System.out.println(item[0].getName());
 System.out.println(item[0].getCode());
 System.out.println(item[0].getUrl());
 System.out.println(regionListItem[0].getID());
 System.out.println(regionListItem[0].getName());

 } catch (JAXBException e) {
 e.printStackTrace();
 }
 }
}
</code></pre>

It gives:

<pre><code>1
Some name 1
Some code
Some Url
2
Some name 2
</code></pre>

I had the same issue, my problem was, that I had two different webservices with two different wsdl-files. I generated the sources in the same package for both webservices, which seems to be a problem. I guess it's because of the ObjectFactory and perhaps also because of the package-info.java - because those are only generated once.

I solved it, by generating the sources for each webservice in a different package. This way, you also have two different ObjectFactories and package-info.java files.

So i had your exception when i used pre-generated classes from a xsd file that was not mine.
The generated xml-object name and namespace(the @xmlroot) was missing from the java-class, so i could not unmarshal it.
Putting the missing URI above the class like this &quot;solved&quot; the problem:
<pre><code>@XmlRootElement(name = &quot;XHE&quot;, namespace = &quot;http://docs.oasis-open.org/bdxr/ns/XHE/1/ExchangeHeaderEnvelope&quot;)
public class XHEType {
</code></pre>
But since i wanted this class to only be in target, this did not suffice.
What i finally came up with was this new class to wrap the generated class in where i put the @xmlroot instead:
<pre><code>@XmlRootElement(name = &quot;XHE&quot;, namespace = &quot;http://docs.oasis-open.org/bdxr/ns/XHE/1/ExchangeHeaderEnvelope&quot;)
public class XHEType2 extends XHEType {
</code></pre>
And the unmarshall code:
<pre><code> JAXBContext jaxbContext = JAXBContext.newInstance(XHEType2.class);
 javax.xml.bind.Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
 XHEType xheType = (XHEType) unmarshaller.unmarshal(reader);
</code></pre>

<pre><code>unexpected element (uri:"", local:"Group"). Expected elements are &lt;{}group&gt;
</code></pre>

Meet an exception when unmarshalling from xml

<pre><code>JAXBContext jc = JAXBContext.newInstance(Group.class); 
Unmarshaller unmarshaller = jc.createUnmarshaller();
Group group = (User)unmarshaller.unmarshal(new File("group.xml"));
</code></pre>

Group class has no any annotation and group.xml just contains data.

Anything can be the cause?

javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"Group")
