Dear friends,
I try to deploy and run the Example Application "TutWD_FlightList_Init", but it's always display the error like the following (see at the bottom of this message).
By the way I'll give your more informations like this:
1) My NWDS and SAP J2EE Engine are the same version as SP09 and my SAP version is SAP ERP Central Component 5.0.
2) the application does not has any errors in the Tasks view of NWDS.
3) all of necessary environments (SLD, SDM, SAP J2EE Engine and JCO) are already setting up and still runing.
4) the testing of connection between SLD and JCO is OK.
5) My SAP system, which I acessing remotely to retrieve th flight data, is currently available and contains flight data.
6) All mapping should be OK, because I tried to develop step by step as the example.
7) the screen after running the application should be following(after "<---" is my comment):
Select the Flight Connection <--- Header text
Departure City <--- 1st Input Field
Arrival City <--- 2nd Input Field
Search <--- Push Button
But for my application, it displays
Select the Flight Connection
Departure City --> An error has occured:
"Failed to process the request."
Please contact your system administrator.
Please advises,
SeMs

Dear Satyajit,
I got more problem and I don't known why, I tried to apply as your recommendation to change the singleton from 'true' to 'false' and deploy & run again. But it's got another error (please see at the bottom of message).
And when I connect to WebDynpro Content Administrator via IE. At the Browse > Deployed Content > Local > local/TutWD_FlightList_Init > Applications > FlightListApp, I saw the error "Failed to find classpath for local/TutWD_FlightList_Init".
By the way at the JCO Connection tab, the status of 2 connections is Green and any connection testing was successfully. Please advise.
PS. I do not sure that my friend has try to test the same example like me on the same server today, May it be the cause of incosistency problem?
Thanks very much for your help,
SeMs

Dear Satyajit,
Sorry for my late reply, I have let my basis to check SLD Setting and will let you know later.
By the way, if the cause of problem is come from my SLD Setting, does the first stack trace error tell about this?
Sorry for my many question, I'm beginner and just try to study NWDS myself.
Thanks very much for your help,

Hi SeMs,
<i><<By the way, if the cause of problem is come from my SLD Setting, does the first stack trace error tell about this?>></i>
No, the stacktrace that you posted in your original mail was because of the singleton issue. Once you fixed that, this one is a new error. That's what I think
Regards,
Satyajit.

Dear Satyajit,
I sent my basis the PDF manual of Post-Installation Guide: SAP Sysem Landscape Directory on SAP Web AS Java 6.40, and let him check step by step. He told everything is OK.
Are there others solution or any point for testing?
Thanks in advances,
SeMs

Hi SeMs,
The problem could be with the prameters that you have set up while adding the ABAP system to the SLD.
Check the parameters of the ABAP system in the SLD once again.
Also note that, this tutorial uses different JCO connections than the default ones.The default ones are named WD_MODELDATA_DEST and WD_RFC_METADATA_DEST. But the ones that this tutorial uses are named WD_FLIGHTLIST_RFC_METADATA_DEST. Check if you have configured this RFC destionation also. In webdynpro content administrator you will be able to see if these have been created.
Also this tutorial uses the BAPI's which are not available in a 4.6C system. Hence the loading of type definitions will fail. Just make sure that you have WAS 6.20 atleast as your backend and that these BAPIs are indeed available.
Regards,
Satyajit.

Dear Satyajit,
Sorry for my late reply. I have check as you advises already, the results are following:
1. I already set the both of JCo connections, WD_FLIGHTLIST_MODELDATA_DEST and WD_FLIGHTLIST_RFC_METADATA_DEST in WebDynpro content administrator. The status of them are green and the result of "Test connection" and "Ping" are return:
"Connection for 'WD_FLIGHTLIST_MODELDATA_DEST' was sucessfully tested with user 'SUKASEM'"
"A ping to the JCo destination 'WD_FLIGHTLIST_MODELDATA_DEST' was sucessfully executed."
"Connection for 'WD_FLIGHTLIST_RFC_METADATA_DEST' was sucessfully tested with user 'SUKASEM'"
"A ping to the JCo destination 'WD_FLIGHTLIST_RFC_METADATA_DEST' was sucessfully executed."
However when I push the button <Run> or <Run as Preview>, it still displays the same error that I sent to you.
2. My backend R/3 system is "SAP ERP Central Component 5.0" and the the function "BAPI_FLIGHT_GETLIST" was OK. The results, which are return, is not empty.
By the way I'm not sure this is the point of problem or not, at page 25 of the tutorial let me define two connections as:
a) A connection to get the needed(dictionary)meta data information
b) A connection to get the read the application data
But for my 'WD_FLIGHTLIST_RFC_METADATA_DES', I set its Data Type as "Application Data" and Destination Type as "Single Server".
Because I could not defined the Data type to "Dictionary Meta Data" and Destination Type to "Single Server Connection" (the default was set at Load-Balanced Connection, but my DEV is single server).
Please advise,
SeMs

Dear Satyajit,
The properties of my context attributed is
For the Model Node's properties:
cardinality = 0..n
collection type = list
initializeLeadSelection = true
name = Bapi_Flight_Getlist_Input
selection = 0..1
singleton = true
supplyFunction =
typedAccessRequired = true
For the Model attribute's properties:
cardinality = 0..1
collection type = list
initializeLeadSelection = true
name = Destination_From
selection = 0..1
singleton = true
supplyFunction =
typedAccessRequired = true
By the way, could you please give me your email? I will capture some of the screen to you for more clearing.
Thanks very much for your help,
SeMs

Dear Karthick and Satyajit,
Thanks very much for your swift reply.For both of your reccommentation. I think I created the mapping context already such as:
This example used adaptive RFC Model call: BAPI_FLIGHT_GETLIST. So I have already defined the context at Custom Controller, mapping the context at SearchView and assigned the value for the inputfield like this
Property = Value <---Header
FromCityInputField = Bapi_Flight_Getlist_Input.Destination_From.City
ToCityInputField = Bapi_Flight_Getlist_Input.Destination_To.City
SearchButton = Event > onAction = Search
Please advise,
SeMs

Hi,
From the stacktrace, it looks like you have not bound your AbstractInputField's value property to any context field.
Check this and try correcting this if that is indeed the case.
Regards,
Satyajit.
