Web application error

Hi!
I'm trying to fix this problem again and have a question.
Web application error
[ QUOTE ]
There is a problem with running web application.
Env.: E810,JAS server(WebSphere 5.0), Enterprise server - all under windows
After opening form and click on several field correct errors appear about empty fields, but then "WEB CLIENT EXCEPTION" appears(see attached picture).
Following errors present in web server log files:

Code:


21 May 2007 12:55:06,968 [ Worker Thread - OWVirtual_Thread_Group6 Assigned To com.jdedwards.runtime.virtual.OWVirtual@2f3e5df] ERROR: {com.jdedwards.system.kernel.CallObject} - *ERROR* CallObject@1f1a25dd: Problem executing function [ValidateUDCValue] lib [CRUNTIME] GetProcAddress failed. Please see Enterprise Server log for details. Business function cannot be found user:USERNAME Env:JPY810


and following error in Enterprise Server logs:
Code:

COB0000012 - GetProcAddress failed CRUNTIME.dll function _ValidateUDCValue@12 Error = 3


This BSFN(ValidateUDCValue) is present in CALLBSFN.dll on server.

As I understood, for web clients all BSFNs should present on Enterprise server(as for Windows client application) and then all functions will be executed on Enterprise Server.
So, how should I do correct server package, which will contain all needed objects?

Thanks

Trying to resolve this issue, I found following:
- ValidateUDCValue (B0000204) defined in CALLBSFN.dll(on Server and Client);
- I made simple search on server and found "ValidateUDCValue" in CALLBSFN.dll and CALLBSFN.pdb files, but same operation in client bin directory found in CALLBSFN.dll and CRUNTIME.dll.
Why client CRUNTIME.dll contains some information about this BSFN and server's dll - not????
