You will get a similar message in the probe test connecton or probe log:
sap_basis (12) login failed, Connector path is not correct, path does not contain sapjco3.dll and sapjco3.jar.
Confirm the variables as described in the probe documentation ie.:
CLASSPATH=D:\sapjco\sapjco3.jar
Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;D:\sapjco\
Java options:
-cp "./*;D:/sapjco/*"
Content of d:\sapjco:
2.02 or later requires additional files in the sapjco folder. It should contain
Release : 9.x or later
Component : UIM - SAP_BASIS
Correct sapjco folde so just download it from Sap Market place with the Sap Administrator help and then apply the probe.
Sap_basis 2.01 version should work as a workaround
