Launch a separate process(terminal window) from Ant [Linux]
I'm trying to launch a separate process from Ant (call Weblogic's startup
script, startWebLogic.sh) in a new window, and have the original window run
in parallel.
This is no problem within Win2000. I use the exec task to call "start" to
launch a new window and give it the command line parameters for
startWebLogic.cmd
When trying to use the exec task for Linux, I can't accomplish the same
thing. I've tried various different methods (xterm, sh) but without success.
I can get a new terminal launched and weblogic runs, but the originating
terminal waits for weblogic to complete before continuing.
I haven't been able to figure out a way to correctly do this and I was
hoping somebody else had. As a last resort, people have suggested I call
"java" and then use "fork" to return control back to Ant.
Any suggestions?

PS: you could write a task which spawned your process through
java.lang.Runtime.exec() in a seperate thread. So what would happen
is your task would spawn the thread, and return control to ant, thereby
running your process in the background.

exec always waits for the process to finish it seems. on window2000, the
start task
spawns another process and then finishes, which is why you see control
return to the
command prompt. On unix, this is built in using the '&' character.
However, the
requested process is still running, so ant will wait for it. what you
really need is
some sort of wrapper that will create an os process which spawns the
desired one
in the background, and exits, without killing it's child processes.
