Hi Thomas,
+) redirection such as "> out.txt" is implemented in the command line
processor or shell. You would need a batch file to do that (a coule of
the regression tests are using that redirection)
+) "executor.setStreamHandler(null)" - should give you a NPE. Please
comment out the line. Without a stream handler you application will block.
+) Another was of getting the output is to use a StreamHandler and pass
a FileOutputStream.
Cheers,

Hi All,
while I am playing with Apache Common Exec I found out that is it
obviously not possible to redirect output into a file via command. I
want to exec cksum file> file.chsum.txt. I get the output of cksum in
ecplise but it is not written to disk.
<code>
public static String CHKSUM_CMD2 = "cksum \"${FILE_NAME}\"> out.txt";
HashMap<String, String> options = new HashMap<String, String>();
CommandLine commandLine = CommandLine.parse(CHKSUM_CMD2);
options.put("FILE_NAME", fileName);
commandLine.setSubstitutionMap(options);
DefaultExecutor executor = new DefaultExecutor();
executor.setStreamHandler(null);
executor.execute(commandLine);
</code>
I suppose that I have to capture the output and write it to disk
afterwards. Or is there other solution ahead?
Many thx, Thomas
