java.lang.ClassCastException: com.sun.org.apache.xerces.internal.dom.ElementNSImpl cannot be cast to

[Brendan cheng]

Hi,
I received an error:
java.lang.ClassCastException: com.sun.org.apache.xerces.internal.dom.ElementNSImpl cannot be cast to hk.itags.core.Log
from jersey client
public interface hk.itags.core.Log {
Date getDate();
String getAuthorName();
}
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class hk.itags.core.neo4j.restclient.Log implements hk.itags.core.Log {
@XmlAttribute(required = true)
Date createdDate;
@XmlElement(required = true)
String authorName;


public Log() {
} public Date getCreatedDate() {
return this.createdDate;
}

public String getAuthorName() {
return authorName;
}}
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({ hk.itags.core.neo4j.restclient.Log.class })
public class Person {

@XmlElementWrapper
@XmlAnyElement
public List<Log> logs = null;


public Person() {
}

public Person(Date updatedDate) {
logs = new ArrayList<Log>();
logs.add(new hk.itags.core.neo4j.restclient.Log(234, updatedDate, "Peter", "ABC", "234", "4556",
"Manager", PersonLogType.NameChange, "TYTT"));
logs.add(new hk.itags.core.neo4j.restclient.Log(245, updatedDate, "Peter", "ABC", "234", "4556",
"Manager", PersonLogType.NameChange, "TYTT"));
}// client side construction}
from my resource file
@GET
@Produces({ "application/xml", "application/json" })
public hk.itags.core.neo4j.restclient.Person getStartup(){
return new hk.itags.core.neo4j.restclient.Person(new Date(System.currentTimeMillis()));
return null;
}my client call like this:
hk.itags.core.neo4j.restclient.Person person = hk.itags.gui.Client.service.path("Person").accept(MediaType.APPLICATION_XML_TYPE).get(hk.itags.core.neo4j.restclient.Person.class);

How can I avoid the cast exception in this case?
