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

Question

unexpected element (uri:\"\", local:\"Group\"). Expected elements are <{}group>

Meet an exception when unmarshalling from xml

Answer 1

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

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

Answer 2

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

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

Hope this helps!

Answer 3

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.

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

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

Answer 4

If none of the above works, try adding

@XmlRootElement(name="Group") to the Group classs.

Answer 5

Luckily, the package-info class isn't required. I was able to fix mine problem with iowatiger08 solution.

Here is my fix showing the error message to help join the dots for some.

Error message

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://global.aon.bz/schema/cbs/archive/errorresource/0", local:"errorresource"). Expected elements are <{}errorresource>

Code before fix

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder={"error"})
@XmlRootElement(name="errorresource")
public class Errorresource

Code after fix

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder={"error"})
@XmlRootElement(name="errorresource", namespace="http://global.aon.bz/schema/cbs/archive/errorresource/0")
public class Errorresource

You can see the namespace added to @XmlRootElement as indicated in the error message.

Answer 6

I already have the same problem and I just change as below:

@XmlRootElement -> @XmlRootElement(name="Group")
