Exception "javax.xml.bind.UnmarshalException: unexpected element ..." thrown when mapping XML to Java using JAXB
Issue
- We are using JAXB to map XML to Java objects in my application like the following:
String xml = ...
JAXBContext context = JAXBContext.newInstance("com.example.app.model");
Unmarshaller unmarshaller = context.createUnmarshaller();
unmarshaller.unmarshal(IOUtils.toInputStream(xml, "UTF-8"));
- However, we get the following
"javax.xml.bind.UnmarshalException: unexpected element ..."exception:
Caused by: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://model.app.example.com", local:"MyData1"). Expected elements are <{}MyData1>,<{}MyData2>,<{}MyData3>[, ...]
