How to get a value from process

[rajashree loganayagi]

Hi,

i wrote a code for executing the batch file using socket program.

i need to get the content of the batch file which has to be sent as a request to the server.

but i cant able to get the content.

Here are my codes :

 public void execBat() throws RuntimeException {
        try {
            int n = 0;
            String a ="";
            while (n < 1) {
Process p = Runtime.getRuntime().exec("cmd.exe /c start c:/shree/test.bat");
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = null;
 while((line=br.readLine())!=null)
             {
            	 System.out.println(line);
             }

  n = n + 1;
                Thread.sleep(1000);
                p.destroy();
                
            }
           
        } catch (IOException io) {
            System.out.println(io.getMessage());
}
}

The problem is that while printing the "line" variable, i get no response in the console.
Can any one please help me....

Thanks in advance.

Moving to Java in General.

Also, read this. You either need to read from p.getErrorStream() as well, in a different thread, or use ProcessBuilder with redirectErrorStream(true) instead of Runtime.exec to create the Process.
