Issue in executing System Command through Java

[ashwin bala]

Hi,
I am trying to execute a system command through java.I am trying to check whether a particular service is running in a
remote PC.When i execute a same command in local PC i.e. without IP Address, then i am getting proper output response.But
when i use remote IP Address and BufferedReader to get the response ,the application is getting hang after
BufferedReader.readLine() method call.. I have attached the code which i have written.

class Test
{	
public static void main(String arg[])
{
	 Process p;
	 Runtime runTime;
	 String process = null;
	 try {
	 	runTime = Runtime.getRuntime();
	 	p = runTime.exec("sc \\xx.xx.xx.xx query gpsvc");      // For Windows
	 	InputStream inputStream = p.getInputStream();
	 	InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
	 	BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
		String line = bufferedReader.readLine();
	 	process = "&";
	 	while (line != null) {
	 		line = bufferedReader.readLine();
	 		process += line + "&";
	 	}
	 	StringTokenizer st = new StringTokenizer(proc, "&");
	 	System.out.println("token size "+st.countTokens());
	 	while (st.hasMoreTokens()) {	
         	String testData = st.nextToken();
	 	bufferedReader.close();
	 	inputStreamReader.close();
	 	inputStream.close();
		}

	 } catch (IOException e) {
	 System.out.println("Exception arise during the read Processes");
	 e.printStackTrace();
	 }
	 
}
}	 

The execution stops after line 17: bufferedReader.readLine(); with out any error
