CairngormStore for Flex 2

Question

I am trying to run CairngormStore for Flex 2 end-to-end.
It looks like the only deployment/configuration problem left
is the configuration of Data Services.
What is already done:
- Flex 2 SDK is installed
- Flex 2 builder is up and running
- Flex 2 Data Service Express is installed with the option
"JRun"
- Cairngorm Library is installed
- Project CairngormStore_2 is created in FlexBuilder (
Project type "Flex Data Service")
- the path to the Cairngorm Library is defined
- the path to the JRun is defined
- CairngormStore is build OK
- JRun starts successfully
Attempt to run the CairngormStore results in run-time alert
message "Products can't be retrieved".
Obviously my deployemnt /configuration of Data Services on
the client and server side is not complete.
Given pretty involved combination of declarative
configuration parameters and configuration files it is
not easy to figure out what the problem is and how to cure
it.
Any hint, advise will be greately appreciated.

matamel, thanks for the reply.
The point is that there the app does not crash, so there is
not much information in the log.
First, after the execution of
public var model : ShopModelLocator =
ShopModelLocator.getInstance();
there is a log message: "didn't find all selected items"
and later after execution of
CairngormEventDispatcher.getInstance().dispatchEvent( new
CairngormEvent( GetProductsEvent.EVENT_GET_PRODUCTS ) );
there is a message issued by
Alert.show( "Products could not be retrieved!" );
So there is not much to analyze so far.
