Invalid "required" attribute

Navigation

I took a project and it is showing compilation error because it is not recognizing the "required" attribute in the following section: 

@XmlElementRef(name = "Nome", namespace = "http://schemas.datacontract.org/teste/teste/teste", type = JAXBElement.class, required = false)

The displayed error is:

  

The required attribute is undefined for the annotation type   XmlElementRef

The problem occurs because you are using Java 6. The required only started to be supported from Java 7, according to documentation . So to work, you'll need to use Java 7 at a minimum.
