how can we disconnect or logout the vcenter connection ?

friends,

            We are disconnecting with the below code

try {
            if (isConnected) {
                vimPort.logout(serviceContent.getSessionManager());
            }
        } catch (Exception e) {
           e.printStackTrace();
            result = false;
        }

Is it correct to close the open socket ? Kindly help me on this.

Thanks
