How to modify BeanInfo of a classe (generated by jaxb xjc)?

Question

I created some classes using JAXB XJC. They follow this pattern (some properties with getters and setters and xml annotations):

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "School", propOrder = {
    "info",
    "students"
})
public class School {

    @XmlElement(name = "Info", required = true)
    protected Info info;

    @XmlElement(name = "Students", required = true)
    protected List<Student> students;

    public Info getInfo(){ return info;}

    public void setInfo(Info value){ info = value};

    public List<Students> getStudents(){ 
       if (students == null) {
            students = new ArrayList<Student>();
        }
       return students;
    }

    public void setStudents(List<Student> elements){
       if (students == null) {
            students = new ArrayList<Student>();
        }
       students.addAll(elements);
    } 

When I use java.beans.Introspector.getBeanInfo and BeanInfo.getPropertyDescriptors to get the class BeanInfo I can see that my School class has a property called students with the WriteMethod being setStudents(List). I believe that the BeanInfo of this class was generated following the default rules of Bean, according to Java Beans specification:

If we discover a matching pair of get<PropertyName> and set<PropertyName> methods that take and return the same type, then we regard these methods as defining a read-write property whose name will be <propertyName>.

So, how can I change the BeanInfo of this class? More precisely, I want to set the WriteMethod of the property students to be another method that does not follow the default rule mentioned above (it would be public void setStudent (Student student){...}). How can I do this?

Only to make sure it is clear... When I use java.beans.Introspector.getBeanInfo and BeanInfo.getPropertyDescriptors to get the class BeanInfo I want to see that my School class has the property students with the WriteMethod being my new set method (setStudents(Student) that does not follow the default rule).

I saw some things here, but it wasn't enough for me...

Thank you!
