Cockpit doesnu0092t work (SAP AII 4.0) - Error in JCO connection
After some days working with the "Cockpit" in AII 4.0, today we can not access to it and we dont know why.
When we execute the transaction /AIN/DTUIURL - Auto-ID Cockpit, we do logon and after that it appears the error:
"Failed to process the request. Please contact your system administrator. Pressing on Show Details, in Error stacktrace we can see the following:
"com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type com.sap.ain.model.utility.types.Syuname could not be loaded: com.sap.dictionary.runtime.DdException: TypeBroker failed to access SLD: Error while obtaining JCO connection."
In fact, we have the same problem (an error in JCO connection) when IDOCs try to be sent from R3 to AII or vice versa. We can see in transaction sxmb_moni of XI system this error.
Does anybody know where the problem could be?
Thanks in advance,
