SAP 6.5 Adapter Connection Error


I am trying to configure a connection with SAP 6.5 adapter. I have provided all the connection details required. When I try to enable the connection it throws the following error.

“Error encountered
[ART.118.5042] Adapter Runtime (Connection): Unable to enable connection resource sap65:connNode_test1.[ART.118.5068] Adapter Runtime (Connection): Exception encountered processing enable connection callback$Client: method getConnectionHandle()J not found”

Could someone please help on this.Thanks,Phani
