JAXB @XmlElements to have minOccurs = 1

Question

So I want to have a list to be annotated with @XmlElements like the following

@XmlElements(
        {
            @XmlElement(name = \"Apple\", type = Apple         


        

Answer 1

I suggest to check:

@XmlElements(
    {
        @XmlElement(name = "Apple", type = Apple.class, required = true),
        @XmlElement(name = "Orange", type = Orange.class, required = true),
        @XmlElement(name = "Mango", type = Mango.class, required = true)
    }
)
