I have seen the error, but I used to get this error only when the host entry was wrong.

I'd suggest check the IP address of the SAP system once again.

Hi Zhu,

I think Starting with JCo 2.1.4 and JCo 2.0.11, JCo requires the new Visual Studio .NET C/C++ runtime libraries on Windows platforms.(found on SAP webpage)

I would recommend you download the new JCO version 2.1.5 found here: http://service.sap.com/connectors

and follow the installation guide. When you still get a problem connecting, you should post the error message here.I hope it helps.

Bye!
