error for getting the data from an api using br.readLine

error for getting the data from an api using br.readLine

hi
the application is hanging while reading the data using readLine() function . actually the data is coming from remote using particular api call see the following code.

StringBuilder sb = new StringBuilder();

String strtemp;
Runtime runtime = Runtime.getRuntime();

Process process = runtime.exec("cmd.exe /C c:\\curl\\curl -X POST -d \"format=json&api_key=MY739HWQW4PWZ1HIJEWVNSOUAF8EJQ4K\";user[email]=useremail;user[password]=userpassword;user[country]=usercountry;user[mobile_phone]=userphone http://staging-orion.sabsebolo.com/users");

Process process = runtime.exec(url);


BufferedReader inputreader = new BufferedReader(new InputStreamReader(process.getInputStream()));
while ((strtemp = inputreader.readLine()) != null) {


sb=sb.append(strtemp);

}

while executing the above while loop the application is hanging . i find that the application gets hanging while executing inputreader.readLine() function.

please can you help to solve this problem
