fire off and wait for executable jar

Hi.
I am using cbuilder 6.
I'm wondering is there any 'recommended' way to fire off an executable
jar file from within my application? I need to wait for it's
completion, and then check to see if it left any files behind. This is
strictly windows.
thanks
Jeff

more.. I tried ShellExecute passing java as the filename and the

parameters in the parameter string, but all I got was a brief dos box
flash.
I put it all in a bat file, but the same thing happened when I used
ShellExecute on the bat file.
I guess I need to try to get the return code from the bat file into my
application.

Ahh. it works. ShellExecute all by itself worked. (I forgot to delete

some files that caused the
jar executable to just be silent).. but how can I get the code
returned by the jar application into
my c++ app?

ok.. this worked fine and I got the return code back..

spawnlp(P_WAIT,"mydir\\dojava.bat","mydir\\dojava.bat","parm1",
"parm2","parm3",NULL);
