Resolution

The root cause is that studio initialised with the wrong version of jar, which needs to be replaced with the official sapjco3.jar file from SAP.

To resolve:

1. Browse to your Talend Studio's installation folder 
2. Go to <Studio installation folder>\configuration\.m2
   epository\org\talend\libraries\com.sap.conn.jco.sapjco
3. Remove com.sap.conn.jco.sapjco 
4. Reinstall sapjco3.jar
