javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"sRAssignments"). Expected elements are

Question

SRAssignments.java (wrapper class):

@XmlRootElement
@XmlType(propOrder = {})
public class SRAssignments
{

@XmlElement(name = "srAssignments", type = SRAssignment.class) private     
List<SRAssignment> srAssignments = new ArrayList<SRAssignment>();

public SRAssignments()
{
}

@SuppressWarnings("javadoc")
public SRAssignments(List<SRAssignment> srAssignments)
{
    this.srAssignments = srAssignments;
}

@SuppressWarnings("javadoc")
public List<SRAssignment> getAssignments()
{
    return this.srAssignments;
}


@SuppressWarnings("javadoc")
public void setAssignments(List<SRAssignment> srAssignments)
{
    this.srAssignments = srAssignments;
}

}

client code:

        StringBuilder getAssignmentsResponse = 
(StringBuilder) RestClientUtil.sendGetMethod(urlGetAssignments
                + URLEncoder.encode(technician, "UTF-8"));
      Unmarshaller unmarshaller =  RestClientUtil.getUnmarshaller(SRAssignments.class);
      reader = new StringReader(new String(getAssignmentsResponse));
      assignments = (SRAssignments) unmarshaller.unmarshal(reader);

XML content in getAssignmentsResponse shows:

<?xml version="1.0" encoding="UTF-8"?><sRAssignments><srAssignment><assignedBy><bonus>0.0</bonus><commission>0.0</commission><educationLevel>1</educationLevel><email>[email protected]</email><empNo>RMGR1</empNo><firstName>first1</firstName><lastName>last1</lastName><role>manager</role><salary>0.0</salary></assignedBy><assignedOn>2012-12-26T14:09:41.763-08:00</assignedOn><comment>remote agent assigning a request...</comment><employee><bonus>0.0</bonus><commission>0.0</commission><educationLevel>1</educationLevel><email>[email protected]</email><empNo>TN1</empNo><firstName>first1</firstName><lastName>last1</lastName><role>technician</role><salary>0.0</salary></employee><serviceRequest><customer><city>city1</city><companyName>companyName1</companyName><custNo>RCN1</custNo><email>[email protected]</email><firstName>first1</firstName><gender>F</gender><lastName>last1</lastName><midInit>K</midInit><phone>4082229871      </phone><state>CA</state><streetAddress>streetAddress1</streetAddress><title>S   </title><zipCode>zipCode   </zipCode></customer><dateCreated>2012-12-26T14:09:38.678-08:00</dateCreated><description>Stress testing, customer is submitting a service request for some repair request.10Request by: Thread-1</description><srNo>107824</srNo><status>2</status></serviceRequest><sraId>34974</sraId><status>1</status></srAssignment></sRAssignments>

Solution

The case on the annotation below is different than the xml that is being read from the response.

@XmlElement(name = "srAssignments", type = SRAssignment.class)

Check your case. The annotation on your end should probably read as below.

@XmlElement(name = "sRAssignments", type = SRAssignment.class)
