-------------------------------------
Hi Julien,
Thanks for your support...... When i changed HashMap to Map it is working.
Still I am confused about the listOrderedMap
In the following code snippet :
List<HashMap> objList =null; //Create a list and it is using the Data
Access layer to fetch the data .
objList = XDA.getInfo(threadId); //in XDA,we fetch the data using the
hibernate jdbc templete:
list = YDAO.getListByQuery(sqlStr.toString(), arr);
return list; // So the return list will be a List of Maps. This value will be
stored in the objList variable.
//set the list objList in a model object called psgrModel
psgrModel.setPassengers(objList);
//pass the model into another method in the same class and fetch the same data
processXInfo(psgrModel);
//in processXInfo(psgrModel) method we are delclaring a list called
lstQueuedPsgrs and stored the queued passengers
List lstQueuedPsgrs = psgrModel.getQueuedPassengers();
Int startIndex=0;
//get the data from the list into the HashMap and then get the value from it
using the key XYZ as set DA layer while
//fetching from the database
String xyz =
(String)(((HashMap)lstQueuedPsgrs.get(startIndex)).get("XYZ"));
It was working fine in the appache common-collection version 1.1 but as we
upgraded it to 3.2 version, its giving the following exception.
java.lang.ClassCastException: org.apache.commons.collections.map.ListOrderedMap
And in this particular class we are importing the java.util package. not common
collection.
Although it is working fine with Map, but can anyone please tell us the reason
why is it getting ListOrderedMap instead of HaspMap???
