serialize objects of type: primitive class

need to identify objects of type primitive class in:

com.thoughtworks.xstream.converters.extended.JavaClassConverter

protected Object fromString(String str) {
try

{ return //*******add this stuff: str.equals("byte") ? byte.class : str.equals("int") ? int.class : str.equals("long") ? long.class : str.equals("float") ? float.class : str.equals("boolean") ? boolean.class : str.equals("double") ? double.class : str.equals("char") ? char.class : //*******up to here... classLoader.loadClass(str); }

catch (ClassNotFoundException e)

{ throw new ConversionException("Cannot load java class " + str, e); }

}
