I followed SAP tutorial to create a SFLIGHT webdynpro and while executing i initially got page not found error. upon analyzing I found SAP Note and activated all required ICF Nodes....despite this, i'm getting a IE screen with

'No switch to HTTPS occurred, so it is not secure to send a password"

"SSO Logon not possible; logon tickets not activated on the server"

...

...

and logon screen ..upon clicking logon it shows a empty screen with 5 java script erorrs...

ST22 trace is as follows:

RUNTIME ERRORS : OBJECTS_OBJREF_NOT_ASSIGNED

EXCEPTIOn : CX_SY_REF_IS_INITIAL

Error analysis shows some error in procedure "DO_CLEANUP" method ...

search in this forum threads revelaed that i need to activate HTTPS & SSO..
