Using the entity:
@Entity
@Table(name = "EMPLOYEE")
public class Employee implements java.io.Serializable, Comparable<Employee> {

    private int id;
    private String firstName;

    public Employee() {
    }

    public Employee(int id, String firstName) {
        this.id = id;
        this.firstName = firstName;
    }



    // ===========================================================
    // getters and setters for the state fields

    @Id
    @Column(name = "ID")
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    @Column(name = "FIRSTNAME")
    public String getFirstName() {
        return firstName;
    }

----------------
Client Code:

        Query query =em.createQuery("SELECT e FROM Employee e WHERE e.firstName = ?1");

        Set<Parameter<?>> sParameters = query.getParameters();
        for (Parameter p : sParameters) {
            System.out.println("parameter name = " + p.getName());
            System.out.println("parameter position = " + p.getPosition());
            System.out.println("pParameter type =" + p.getParameterType());
           
            if (query.isBound(p)) {
                System.out.println("isBound believes there is a value bound to the parameter:" + p);
            } else {
                System.out.println("query isBound = " + query.isBound(p));

            }
            Integer pos = p.getPosition();
            if (pos != null) {
                if (pos == 1 || pos == 2) {
                    String sActual = p.getName();
                    if (sActual != null) {
                        System.out.println("getName() - Expected: null, actual:" + sActual);
                    }
                    try {
                        String sExpected = "java.lang.String";
                        sActual = p.getParameterType().getName();
                        if (!sActual.equals(sExpected)) {
                            System.out.println("getParameterType().getName() - Expected: " + sExpected + ", actual:" + sActual);
                        }
                    } catch (IllegalStateException ise) {
                        System.out.println("warning: getParameterType().getName() threw IllegalStateException, this is not considered a failure");
                    }
                } else {
                    System.out.println("getPosition() returned an invalid position:" + pos);
                }
            } else {
                System.out.println("getPosition() returned null");
            }

---------------
Output:

parameter name = 1
parameter position = null
Parameter type =class java.lang.String
query isBound = false
getPosition() returned null

Output:
