I am trying to automate a desktop application. I got the object list for a Command Prompt, i got an object called "uknVertical" as scrollbar.

But when called verifyScrollbar(uknVertical), the method is always returning 0 and when i call scrolldown("") i am getting the below error.

Exception in thread "main" com.cobra.ldtp.LdtpExecutionError: unsupported method called: scrolldown
at com.cobra.ldtp.Ldtp.doAction(
at com.cobra.ldtp.Ldtp.scrollDown(
at com.ldtp.cmdCapture.main(

Could you please let me know if i am invoking the function correctly.

Please find my code snippet below.

public class cmdCapture {

public static void main(String[] args) {

String WinName = "Command*";
Ldtp ldtp = new Ldtp(WinName);
// ldtp.launchApp("Command*");

String[] obj = ldtp.getObjectList();

for (String str : obj)
