I have created the JAXB classes using the xjc jaxb java classes generator. now the generated JAXB files having an error on the root element:

"Cannot resolve XML element declaration with namespace '' and name 'build-summaries' in this context"

@XmlRootElement(name = "build-summaries")
public class BuildSummaries {

Can somebody help me resoving this? when we create the single XSD file, Do we need to create the namespace?

Answer 1

If you want the build-summaries element to be in a namespace, then you need to add targetNamespace="http://example.com/mynamespace" to the xs:schema element's start-tag (substituting the name of the namespace you want for http://example.com/mynamespace).
