[morph-user] help required

[<pra...@wi...>]

Hi,

I am trying to morph objects from str String using dynaMorpher in
Holiday Bean through this code.I am using Spring framework. 

String[] dateFormats = new String[] {"yyyy-MM-dd"};

JSONUtils.getMorpherRegistry().registerMorpher (new DateMorpher
(dateFormats));

String str = "{param:[{\"date\":\"2009-06-15
00:00:00\",\"description\":\"holiday1\"},{\"date\":\"2009-06-17
00:00:00\",\"description\":\"holiday2\"}]}";

JSONObject jsonObject = JSONObject.fromObject(str);

Collection expected =
JSONArray.toCollection(jsonObject.getJSONArray("param"));

MorpherRegistry morpherRegistry = JSONUtils.getMorpherRegistry();

Morpher dynaMorpher = new BeanMorpher(Holiday.class,morpherRegistry);

morpherRegistry.registerMorpher(dynaMorpher);

Holiday holiday=new Holiday();

for (Iterator iterator = expected.iterator(); iterator.hasNext();) {

holiday = (Holiday) morpherRegistry.morph(

Holiday.class, iterator.next());

System.out.println(holiday.getDescription());

System.out.println(holiday.getDate());

}

When I run this code in main method it works without any error. But when
I put this code in some other method it throws following error.

14:57:44,673 INFO  [BeanMorpher] Property 'com.entity.Holiday.class'
