Am I missing a big pink elephant here?

that does not seem to launch the process in the background though. I want to launch the java app, then continue on with my script (also, the pid isn't returned until I quit the java app - not real helpful). It seems that an '&' is necessary here, no?

But anyway, I had already tried other things using open() as well, but I couldn't get them to work:

$kid = open (FH, "java JavaApp | &");
print $kid;

[download]

(gives "no such file or directory" message, $kid not returned until java app is quit)

$kid = open (FH, "java JavaApp & |");
print $kid;

[download]

(causes my script to hang, $kid not returned at all)

for some reason, if I redirect the stderr to /dev/null:

$kid = open (FH, "java JavaApp 2> /dev/null & |");
print $kid;

[download]

the app DOES run in the background, $kid is returned immediately, HOWEVER, the app doesn't quit when I end the script. If I take the number returned in $kid (eg, 1001), and manually try to kill the process with it I get:

kill 1001
-bash: kill: (1001) - No such process

[download]

Also tried:

`java JavaApp &`

(gives "no such file or directory" message)

I have found lots of stuff on the net on how to start a background process in perl, but nothing on how to kill one (in a perl script).
