Error in executing a while loop

[rajashree loganayagi]

Hi,

I wrote a socket program, which needs to run a shell program in the client-side for every 10secs. The output of the shell program has to be sent to the server.

The problem is in the client-side, where i need to run the shell continuously whithout any break.

For this i used while loop which is set to true. But i cant run the shell program continuously. i noticed that the client side runs for upto 6 or 7times and remains silent.

Here the the following codes:

while (true) {

               
            	Process p1 = runtime.exec("sh /glotam/Bankareas/cboj/bnk/bnk.run/test.sh");
            	 istream = p1.getInputStream();
                int i = 0;

                while ((i = istream.read()) != -1) {
                    val1 = val1 + (char) i;
                }
              
                val2 = ipAddress + "#" + val1;
                out.println(val2);
          
                Thread.sleep(10000);
            }

This code works fine with smaller amount of input. But for larger case it doesn't works.

Can anyone help me....


Thanks in advance.

When Runtime.exec() won't. Read it, not reading from p1.getErrorStream() is the likely cause of your problem.
