Unix command from jsp does not work
Hello everybody
I'm trying to execute a unix command from within the jsp page, smth like
Process p = Runtime.getRuntime().exec(new String[]{"/bin/sh","-c","ls -l >
dat.foo"});
.. And it doesn't work, I mean nothing happens , no error messages, nothing
However this piece of code works fine in a standalone Java program
What am I doing wrong?
My system: Linux Red Hat 7.2, Apache 1.3.22, Tomcat 4.0.3, WARP Connector
Thanks in advance
roman

ls -l > foo.dat was just an example
My task is to envoke a perl script from jsp which looks like this:
Process p = Runtime.getRuntime().exec(new String[]{"/bin/sh","-c","echo
blah@foo.com | /root/bin/bulkmakemail"});
For some reason I'm not able to run ANY unix commands from jsp
Can it be because of "user privileges" , do I have to run tomcat as root?
I know it is dangerous
Or is there any other way I can fix this problem?
Thank you

Well, if the ls -l happens to not find the file foo.dat, then it's proper
result would be to, essentially, "do nothing". So, perhaps it actually is
working, and the file you're running 'ls' on isn't there?
P.S. just an FYI, but you do realize that the java.io.File object does
pretty much what 'ls' will do for you, right? Plus, it's portable...
