How to persist/save Objects in XML Spring MVC

I want to save Object values in xml file which is located in my Spring MVC project's SRC folder.

I little bit know about marshaling and un-marshaling concept of JAX-B for saving object to xml file.

example ,
    Employee emp1=new Employee(1,"Robin",50000);  
    File file =new File("c://myfiles//employee.xml"))  
    marshallerObj.marshal(emp1, new FileOutputStream(file); 

here above code save the my emplyee object to employee.xml file which is locate in C/myfiles folder.

so how i can use same code in spring controller like below,

@RequestMapping(value="/saveNotice",method=RequestMethod.POST)
public void saveNotice(Notice notice){

    Employee emp1=new Employee(1,"Robin",50000);  
    File file =new File("src/employee.xml"))  
    marshallerObj.marshal(emp1, new FileOutputStream(file); 
}

need help here........

thanks.
