how to take a generic JAXBElement as an input

I have a method 

public Response xyz ( JAXBElement<T> request ) {
......
}

two different places it is getting called with different JAXBElement. One with xyz(JAXBElement<a>) and other with xyz(JAXBElement<B>)

How can I make my method intake generic so that it works with both the methods?

Please try:

xyz(JAXBElement<?> myElement);

Please see this tutorial on generics:

So what is the supertype of all kinds of collections? It's written Collection<?> (pronounced "collection of unknown"), that is, a collection whose element type matches anything. It's called a wildcard type for obvious reasons. We can write:

void printCollection(Collection<?> c) {
    for (Object e : c) {
        System.out.println(e);
    }
}

and now, we can call it with any type of collection.
