NativeProcess problem

Hello,

I’m working on an AIR 2 application (a packager for air applications into *.exe). One of the options in the application is to check the validity of certificate’s password. I’m using standardOutput method:

private function checkCertPass():void{
	        file = new File();
	        file.nativePath = "C:/WINDOWS/system32/"
        	file = file.resolvePath("cmd.exe");
        	nativeProcessStartupInfo = new NativeProcessStartupInfo();
        	var processArgs:Vector.<String> = new Vector.<String>;
        	processArgs.push(javaPath.text);
        	processArgs.push("-jar");
        	processArgs.push(adtPath.text);
        	processArgs.push("-checkstore");
            processArgs.push("-storetype");
            processArgs.push("pkcs12");
            processArgs.push("-keystore");
            processArgs.push(certPath.text);
            processArgs.push("-storepass");
            processArgs.push(passField.text);           
        	nativeProcessStartupInfo.arguments = processArgs;
        	nativeProcessStartupInfo.executable = file;
        	nativeProcess = new NativeProcess();
        	nativeProcess.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onCertOutputData);
        	nativeProcess.start(nativeProcessStartupInfo);
		}
		private function onCertOutputData(event:ProgressEvent):void{
			var certResponse:String = new String();
			certResponse = nativeProcess.standardOutput.readUTFBytes(nativeProcess.standardOutput.bytesAvailable);
			trace(certResponse);
			outputField.enabled = true;
			outputField.text += certResponse;
			if(certResponse.substr(0,5) == "valid"){
				trace("Correct password!");
				exeField.enabled = true;
				nativeProcess.removeEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onCertOutputData);
				nativeProcess.exit();
			}else{
				trace("Incorrect password! Error...");
				exeField.enabled = false;
				nativeProcess.removeEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onCertOutputData);
				nativeProcess.exit();
			}
		}

but I cannot establish communication i.e. all I receive after performing the code above is:

Microsoft Windows XP [Version 5.1.2600]

What is wrong with this code? Why I can’t receive the response?

Thanks in advance,
