EODisplayGroup problem

Hi All

I am using EODisplayGroup to insert an object into database from Java
Client application.
Here is the code snippet:-

1.	EODisplayGroup _barCodeScan1;
2.	EOEditingContext _editingContext;
3.	NSMutableDictionary objDict = new NSMutableDictionary();
4.	objDict.setObjectForKey("201","centerNumber");
5.	objDict.setObjectForKey("StudentData","data");
6.	objDict.setObjectForKey("101","scannerSerialNumber");
7.	objDict.setObjectForKey("04/04/04","timestamp");
8.	_barCodeScan1.setInsertedObjectDefaultValues(objDict);
9.	_barCodeScan1.insert();
10.	_editingContext.saveChanges();

At line no 9, I am getting the following error

<com.webobjects.eocontrol.EOGenericRecord 0xc1a0eb> takeValueForKey():
attempt to assign value to unknown key: 'centerNumber'. This class does
not have an instance variable of the name centerNumber or _centerNumber,
nor a method of the name setCenterNumber or _setCenterNumber

It seems that while inserting default object displaygroup is looking for
instance variable in EOGenericRecord Class instead of actual Entity
Class.

I try to print the name of the Class associated with datasource like
this
String locEntityName =
_barCodeScan1.dataSource().classDescriptionForObjects().entityName();
It is printing the correct Entity name but still problem is there while
running the above code.

Can anybody tell me what could be the problem here?

Thanks
Regards
