I am attempting to scan my entity class for JPA @Column
annotation using the code below;
for (Method m : User.class.getMethods())
{
if (m.isAnnotationPresent(javax.persistence.Column.class))
{
javax.persistence.Column column = m.getAnnotation(javax.persistence.Column.class);
System.out.println(column.name());
}
}
But I am getting below exception. I can confirm that I have javax-api jar loaded as part of my dependencies. Do anyone know what I am doing wrong?
