executing a python script on windows using java Runtime.exec -

-

i have python script runs on windows , uses win32 extensions , wmi information. if run script using command line, executes perfectly. but, if try run same script using java runtime.exec("python myscript.py") seems blocked on waitfor(). code this:

process p = runtime.getruntime().exec("python myscript.py"); int exitcode = p.waitfor();

if try use same java code simple python script like

print "hello world"

i exitcode 0, means works. can execute python script imports wmi library, using java runtime.exec()?

thanks

one reason io buffers full , need flushed, try flushing both stdout , stderr process in java code (example code).

alternatively, try redirecting output nul or text file 1 of following arguments exec:

cmd.exe /c python myscript.py > nul 2>&1  cmd.exe /c python myscript.py > output.txt 2>&1

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
