capture echoed text from shell script

Related, and simpler, question -

Q: When I execute the following code, the shell process executed here hangs. Also, the file /tmp/secLevel is never created (and never modified if it already exists).

Runtime.getRuntime().exec("/bin/ksh -c /usr/local/bin/getSecLevel > /tmp/secLevel");

Here are the contents of /usr/local/bin/getSecLevel:

#!/bin/ksh

level=`replace me later`

echo $level

exit

Process proc = Runtime.getRuntime().exec("command");

InputStream in = proc.getInputStream();

proc.waitFor();

byte[] result = new byte[in.available()];

in.read(result);

in.close();

System.out.println(new String(result));

it works only if no errors occurs.

To catch Errors use getErrorStream() method.

good luck
