Hi guys,
I am choosing in between SOJO and JSON-lib for my new project. JSON-lib
seems to be well-maintained however I am having a difficulty to convert from
JSON to a bean with this structure:
BeanA{
get/set: BeanB[]
get/set: String, whatever
}
BeanB{
get/set: String, whatever
}
Sample code and error:
JSON json = JSONSerializer.toJSON(REMOTE_ISSUE_STRING_1);
Map map = new HashMap();
map.put("customFieldValues", RemoteCustomFieldValue.class);
JSONObject.toBean((JSONObject) json, RemoteIssue.class, map);
net.sf.json.JSONException: Error while setting property=customfieldId

By doing some debugging and tracing, I found these lines in JSONObject:
if( List.class.isAssignableFrom( pd.getPropertyType() ) ){
Class targetClass = findTargetClass( key, classMap );
targetClass = targetClass == null ? findTargetClass(
name, classMap )
: targetClass;
...
}else{
Object array = JSONArray.toArray( (JSONArray) value,
beanClass, classMap );
It is obvious that beanClass as RemoteIssue is not going to work. I have
tried putting RemoteFieldValue[].class into the classMap too, but I knew
that's not going to change anything.
Is there any workaround that you guys can suggest? Or should I raise a
feature/bug request on this?
