Error - unable to establish JCO connection with SSO
I have implemented XSS on WebDP and this is working fine. So my JCO connections SAP_R3_HumanResources must be configured correctly. However I have just done the 'GetFlight' BAPI tutorial and upon execution I get the error:
'com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCException: Could not create JCOClientConnection for logical System: SAP_R3_HumanResources - Model: class com.sap.tut.wd.flightlist.model.FlightModel. Please assure that you have configured the RFC connections and/or logical system name properly for this model!'
'User not authenticated (is anonymous) - unable to establish JCO connection with SSO'
Can anyone help here?
