        employees = null;
        this.descriptor = descriptor;
        this.outputFile = outputFile;
        this.convertFile = convertFile;
Methods Summary
public voidconvert()

This will make some simple changes to the descriptor and write it back out to a new file, in a converted form. 

         
        // Load up the mapping information
        Mapping mapping = new Mapping();
        mapping.loadMapping(MAPPING_FILENAME);
        
        // Marshall using that information
        Marshaller marshaller = new Marshaller(new FileWriter(convertFile));
        marshaller.setMapping(mapping);
        marshaller.marshal(employees);
public voidlist(boolean validate)

This will list some basic information about the hr.xml deployment descriptor.

param
validate whether or not to validate the descriptor when processing

        
        // Unmarshall
        employees = Employees.unmarshal(new FileReader(descriptor));
        
        // Do some basic printing
        System.out.println("--- Employee Listing ---\n");
        Employee[] employeeList = employees.getEmployee();
        for (int i=0; i<employeeList.length; i++) {
            Employee employee = employeeList[i];
            System.out.println("Employee: " + employee.getName());
            System.out.println("Organization: " + 
            	employee.getOrganization().getName());
            System.out.println("Office: " + 
                employee.getOffice().getAddress().getCity() + ", " +
                employee.getOffice().getAddress().getState() + "\n");
        }
public static voidmain(java.lang.String[] args)

        try {
            if (args.length != 3) {
                System.out.println("Usage: java javajaxb.EmployeeLister " +
                    "[web.xml filename] [output.xml filename] [convert.xml filename]");

        } catch (Exception e) {
            e.printStackTrace();
        }
public voidmodify()

This will make some simple changes to the descriptor and write it back out to a new file. 

        
        // Add a new employee
        Employee employee = new Employee();
        employee.setName("Ben Rochester");
        Address address = new Address();

        office.setAddress(officeAddress);
        employee.setOffice(office);
        
        // Add employee to list
        employees.addEmployee(employee);
        
        // marshal
        employees.marshal(new FileWriter(outputFile));
