Runtime exec exception

The method that executes the commands is as follows:

private BufferedReader executeRuntime(String command)

{

Runtime runtime = Runtime.getRuntime();

try

{

Process process = runtime.exec(command);

process.waitFor();

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

return bufferedReader;

}

catch(InterruptedException e)

{

System.out.println("The process has been interrupted");

System.exit(1);

}

catch(IOException e)

{

System.out.println("Runtime exception");

e.printStackTrace();

System.exit(1);

}

return null;

}

And to invoke an external process, I do

BufferedReader bufferedReader = executeRuntime("./prog calendars1.txt"), where ./prog is the compiled executable parser and calendars1.txt is the file to parse, and bufferedReader contains the output from this process.

I have tested the above code with executeRuntime("ls") and it works fine and there's also no problem with the executable parser. But the two things just cannot work out when put together. Any ideas?

you are right, it was just a typo in my post; it was actually "./prog calendars1.txt" in the program but still gives run time exception.

This is so weird, in the code i clearly put "./" and it automatically turned to ".\" ?! Sorry to confuse anyone, but I'm realy at the end of my tether and haven't got clue how to fix this up. Could anyone help please
