cannot find symbol method required() javax.xml.bind.annotation.XmlElementRef

Question

I am getting the below error when using the jdk 1.6 but it is working in 1.7

cannot find symbol method required() javax.xml.bind.annotation.XmlElementRef

any idea?

    @XmlElementRef(name = "test", type = JAXBElement.class, required = false)
    protected JAXBElement<String> test;

Answer 1

Check documentation of XmlElementRef annotation in Java 1.6 here. There is no required element in it. That is why you are getting this exception.
