I am getting the following error when trying to convert xml response to java objects using jaxb

 javax.xml.bind.UnmarshalException: unexpected element (uri:"http://SOMETHING/doc/2006-03-01/", local:"Name"). Expected elements are <{}Name>,<{}IsTruncated>,<{}MaxKeys>,<{}Contents>,<{}Prefix>,<{}Marker>

Here is my XML :

 <ListBucketResult xmlns="http://something/doc/2006-03-01/"> <Name>test2</Name> <Prefix/> <Marker/> <MaxKeys>3</MaxKeys> <IsTruncated>false</IsTruncated> <Contents> <Key>metadata.xml</Key> <LastModified>2012-09-04T08:29:36.000Z</LastModified> <ETag>6b836fd43c402681506926b2248ec418</ETag> <Size>3258</Size> <StorageClass>STANDARD</StorageClass> </Contents> </ListBucketResult>

And my java object classes are something like this

 @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "name", "prefix", "marker", "maxKeys", "isTruncated", "contents" }) @XmlRootElement(name = "ListBucketResult") public class ListBucketResult { @XmlElement(name = "Name", required = true) protected String name; @XmlElement(name = "Prefix", required = true) protected String prefix; @XmlElement(name = "Marker", required = true) protected String marker; @XmlElement(name = "MaxKeys") protected int maxKeys; @XmlElement(name = "IsTruncated") protected boolean isTruncated; @XmlElement(name = "Contents", required = true) protected ListBucketResult.Contents contents; @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "key", "lastModified", "eTag", "size", "storageClass" }) public static class Contents { @XmlElement(name = "Key", required = true) protected String key; @XmlElement(name = "LastModified", required = true) @XmlSchemaType(name = "dateTime") protected XMLGregorianCalendar lastModified; @XmlElement(name = "ETag", required = true) protected String eTag; @XmlElement(name = "Size") protected int size; @XmlElement(name = "StorageClass", required = true) protected String storageClass;

and finally my unmarshalling code is :

 JAXBContext jc = JAXBContext.newInstance(ListBucketResult.class); Unmarshaller unmarshaller = jc.createUnmarshaller(); unmarshaller.setEventHandler(new javax.xml.bind.helpers.DefaultValidationEventHandler()); JAXBElement element = (JAXBElement) unmarshaller.unmarshal (inputStream); ListBucketResult customer = (ListBucketResult) element.getValue();

Could someone please let me know what am i doing incorrect ?

You can use the @XmlSchema annotation on a package-info class to control the namespace qualification. If you have already written a package-info class make sure it is being compiled (some versions of ant had problems with package-info classes).

package-info

@XmlSchema( namespace = "http://something/doc/2006-03-01/", elementFormDefault = XmlNsForm.QUALIFIED) package example; import javax.xml.bind.annotation.XmlNsForm; import javax.xml.bind.annotation.XmlSchema;

The XML document contains elements which are part of the 'http://something/doc/2006-03-01/' namespace, but the annotated java class is not associated with that namespace. Try changing the @XmlType annotation to:

@XmlType(name = "", namespace="http://something/doc/2006-03-01/", propOrder = { ...

Hi , Changing this didnt help. @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", namespace="something/doc/2006-03-01", propOrder = { "name", "prefix", "marker", "maxKeys", "isTruncated", "contents" })
Regardless of mechanism, the problem is a namespacing issue. The exception method indicates that an element with a fully-qualified name of {SOMETHING/doc/2006-03-01}Name was provided (which is correct based on the xml provided) but that an element of {}Name (among others) is expected. The latter is an element in the default namespace. Is the exception exactly the same now or has it changed slightly?
Hi Thanks for all the comments. It is fixed just by removing @XmlType(name = "", propOrder = { "name", "prefix", "marker", "maxKeys", "isTruncated", "contents" })
Adding the namespace param to @XmlType annotation worked great for me!

I was getting similar error org.codehaus.jackson.JsonParseException and javax.xml.bind.UnmarshalException : with linked exception: [javax.xml.bind.UnmarshalException: unexpected element (uri:"sometext", local:"elementA"). Expected elements are .

This is when integrating RESTEasy and Spring with my DTO's generated using JAXB. I was using Jackson for conversion.

To solve it I introduced the Jackson library in the Maven dependency and it solved my problem. The jackson dependency that is specific to this was 

 <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-xc</artifactId> <version>1.9.9</version> </dependency>

There were other Jackson jars as well which I needed, so my POM Essentially looked as below. 

 //The jackson-core-asl jar contains streaming JSON parser and generator interfaces and implementations <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-core-asl</artifactId> <version>1.9.9</version> </dependency> //Ability to use JAXB annotations containing classes needed to add XML compatibility support. <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-xc</artifactId> <version>1.9.9</version> </dependency> //Mapper jar contains functionality for data binding: <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.9</version> </dependency> //This dependency makes a JAX-RS implementation like Jersey,RESTEasy use Jackson for binding of JSON to-from Java objects <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-jaxrs</artifactId> <version>1.9.9</version> </dependency>
