Hi,
The following code runs fine from a command line application,
returning information from the exec() Process. But when the code is
executed in a servlet, the servlet seems to hang. The system process is
starts but can't seem to communicate with the servlet. Is there any
reason a servlet can't read the input stream from a Process?
-----<snip>
//execute the system command.
try {
Runtime shell = Runtime.getRuntime();
Process p = shell.exec( cmd);
//Get the input stream of the subprocess.
BufferedReader in = new BufferedReader(new InputStreamReader(
p.getInputStream()));
//Get the error stream of the subprocess.
BufferedReader err = new BufferedReader(new InputStreamReader(
p.getErrorStream()));
String line;
while ( ( line = in.readLine()) != null)
System.out.println( line);
while ( ( line = err.readLine()) != null)
System.out.println( line);
} catch (IOException e) { System.out.println( e.getMessage());}
---------<snip>
Thanks
