ECC 6 : Internet Services crashes

Question

Hello,
I hope someone can help me.  We're busy with upgrade R/3 4.7 to ECC 6 and EP 6 to EP 7.  We have HR.  What a mission!  Everything is an issue!
I have to migrate existing custom Internet Services, register them in the ICF to make them work in an EP7 IAC iView. 
I've done everthing as described in help.sap.com's document "Migrating existing ITS services", that meanse :
-> I see them in SE80 (and can edit them)
-> Have published them
-> Have created a service in SICF with HTTP handler CL_HTTP_EXT_ITS
-> iView points to IAC service
iView crashes with :
The URL http://ypfsp003.sanlam.co.za:8010/sap/bc/gui/sap/its/ywfws90100004h was not called due to an error.
Note
The following error text was processed in the system SP1 : Communication failure
The error occurred on the application server ypfsp001_SP1_00 and in the work process 1 .
The termination type was: IMC_CANCEL_TX
The ABAP call stack was:
Method: IF_HTTP_EXTENSION~HANDLE_REQUEST of program CL_HTTP_EXT_ITS===============CP
Method: EXECUTE_REQUEST of program CL_HTTP_SERVER================CP
Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
Module: %_HTTP_START of program SAPMHTTP
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system SP1 in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server ypfsp001_SP1_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 1 in transaction ST11 on the application server ypfsp001_SP1_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.
Error code: ICF-IE-http -c: 200 -u: 309157 -l: E -s: SP1 -i: ypfsp001_SP1_00 -w: 1 -d: 20060807 -t: 122739 -v: IMC_CANCEL_TX -e:
Can anyone help!???  I sure hope so.

Hi Charmaine,
I also like you doing an upgrade of HR from 46C to ECC 6.0. I am also having nightmare every day. The problem that you  are encoutering may be due to setting of the parameters in the SICF. Make sure you set ~Theme, ~GenerateWebdynpro = 1, ~webtransaction type as EWT. It is all about setting the parameters in SICF. There is no proper documentation, we did trial error and made all the ess services working in ITS. We have another problem with the workflows. BWSP is not supported anymore and UWL has some issue in launching the workflow that are based on Integrated ITS IACs. IS the workflow working for you?
Lets be in touch closely,  i think very few have entered into this mission.
my email address is [email protected] and my contact no. is [phone].
