problema resolvido da seguinte maneira:
try
{
InputStream in = new FileInputStream("C:\\teste.xml");
XMLDecoder teste = new XMLDecoder(in);
java.util.Vector v = (java.util.Vector)teste.readObject();
for(int i=0;i<v.size();i++){
String [] s = (String [])v.get(i);
System.out.println(s[0]+" - "+s[1]);
}
}
catch(Exception e)
