You can find a lot of questions like this in this site but none has solved my issue.
This is my XML :
<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<lookupInstances xmlns='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<lookupParameters>
<lookupParameter name='businessArea'>PQAA</lookupParameter>
<lookupParameter name='MEMBERNUMBER'>ANTHONY1900</lookupParameter>
</lookupParameters>
</lookupInstances>
I have created the Jaxb class using the XJC compiler and the file created is as :

Unmarshal Code :
public LookupInstances unmarshallXmlRequest(String xmlReq)
{
LookupInstances instances = null;
try {
JAXBContext jc = JAXBContext.newInstance( LookupInstances.class );
Unmarshaller u = jc.createUnmarshaller();
StringBuffer xmlStr = new StringBuffer( xmlReq );
StringReader strReader = new StringReader( xmlStr.toString() );
StreamSource strSource = new StreamSource(strReader);
Object o = u.unmarshal( strSource );
instances = (LookupInstances)o;
} catch (JAXBException e) {
e.printStackTrace();
}
return instances;
}
I got this error :
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
Please help.
Below is some information that should help:
XML
Below is a portion of your XML. One thing to note is the xmlns
attribute. This is a special attribute and refers to namespace qualification within the XML document.
<lookupInstances xmlns='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<lookupParameters/>
</lookupInstances>
Below is another version of the XML with the same namespace qualification:
<abc:lookupInstances xmlns:abc='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<abc:lookupParameters/>
</abc:lookupInstances>
When you remove the xmlns
attribute the namespace qualification is removed. The document below is not equivalent to the two above.
<lookupInstances name='LKIMGR'>
<lookupParameters/>
</lookupInstances>
Your Error
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
This error indicates that you have not mapped the namespace qualification correctly.
Mapping the Namesapce Qualification in JAXB
Namespace qualification in JAXB is done using the package level @XmlSchema
annotation. Package level annotations go in package-info.java
. Below is the complete source for this class. If you already have a package-info.java
source file ensure it is being compiled and packaged with the rest of your classes.
@XmlSchema(
namespace = "http://www.pqr.com/awd/rest/v1",
elementFormDefault = XmlNsForm.QUALIFIED)
package your_package;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
XML Schema
If you are generating your model from an XML Schema make sure this namespace qualification is properly define there. It will look like:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.pqr.com/awd/rest/v1"
xmlns="http://www.pqr.com/awd/rest/v1"
elementFormDefault="qualified">
</xs:schema>
