JAXB: code generation of elements with maxOccurs property set in the xsd file don´t get a set-method in the java class

I have a xsd file called Person with some elements. Some of the elements have both properties minOccurs and maxOccurs set. Two lines in the xsd file could look like this. 

<xsd:element name="NameOfElement" minOccurs="0" maxOccurs="unbounded">
<xsd:element name="NameOfAnotherElement" minOccurs="0">

In NetBeans I want to generate Java classes of this xsd file using JAXB. All elements that just have the minOccurs property get both a set and a get method in the generated Person java file, but the elements that have both minOccurs and maxOccurs properties set in the xsd file become a List. So the above xsd lines become this after the generation:

@XmlElement(name = NameOfElement)
protected List<Person.NameOfElement> nameOfElement;
@XmlElement(name = NameOfAnotherElement)
protected Person.NameOfAnotherElement nameOfAnotherElement;

The strange thing is that the variable nameOfAnotherElement gets both a set and a get method in the Person java class and nameOfElement only gets a get method.

Why don´t elements that become a List<> in the Java code get a set method (those elements that have both properties minOccurs and maxOccurs set in the xsd)?

So my problem is that I cannot set the NameOfElement to a Person object because it misses a set method, but it contains a get method! Why is that so?

You can use a plugin to force XJC generate setters for collections:

If you have maxOccurs set to != 1, it can contain multiple instances of that element, so it becomes a list.

You should use the get method, and then add elements to that list. Something like this:

List<Person.NameOfElement> myList = doc.getNameOfElement();
myList.add(obj);

Edit: if you already have a list you want to use you can do the follwing:

doc.getNameOfElement().addAll(myList);
