Get "Class" object from generic type T

I want to make generic function that return Object representation of XML document (using JAXB). I need to pass "class" object to JAXBContext constructor, but how I can get it from T?

public <T> readXmlToObject(String xmlFileName, T  jaxbClass) {
   JAXBContext context = JAXBContext.newInstance(T.class); // T.class - here error, how to get it?
   .......
}
