Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {

    MyClass o = new MyClass(123);

    XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(new FileOutputStream("outfilename.xml")));

    String[] propertyNames = new String[] { "prop" };
    encoder.setPersistenceDelegate(MyClass.class, new DefaultPersistenceDelegate(propertyNames));

    encoder.writeObject(o);//from  www  .ja v  a 2  s  .c o m
    encoder.close();

}
