I'm trying to invoke a Java command-line program from my Python program on Windows XP. I cannot get the paths in one of the arguments to work right.
The instructions for the program describe the following for the command-line arguments: java -jar sforcedataloader.jar -Dsalesforce.config.dir=CONFIG_DIRECTORY They also give an example: java -Dsalesforce.config.dir=c:\config -jar sforcedataloader.jar If I type the example above at the cmd.exe command line the thing works (assuming I have the config file in c:\config). What doesn't work is these two lines: cmd = r'java -jar sforcedataloader.jar -Dc:\config' os.system(cmd) I have tried (not entirely systematically but pretty exhaustively) every combination of backslashes in the cmd string, e.g.: -Dc\:\\config -Dc:\\config -Dc\\:\config -Dc\\:\\config etc. No matter what I do, the program outputs that it cannot find the config file. I cannot tell whether this is a java thing (why are there three different styles for argument on the same command line? In addition to "-jar xxx" and "-Dxxx=yyy" you can also put "xxx=yyy" for some options... wth?), Windows lame cmd.exe shell (is that program invoked by Python's os.system function?), or something else that is messing up. It drivin me crazy though. (Come to think of it, Windows paths have been a persistent thorn in my side for two years of Python development at my company.) Anybody have any suggestions? p.s. 1. I would like to qualify the claim above that the example works at the command-line. I'm not completely certain exactly which form of invocation was successful at the command line, but at least one of them was and that one definitely didn't work from Python. 2. I have a work-around available to me, which is that the program will look for the configuration file in the current directory if the command-line option isn't specified. I'd much rather be able to specify a directory on the command line, so that I can have multiple simultaneous invocations, and so that I can have the configuration file not be in the directory where the Python program is, or alternatively not have to change my directory (since I don't fully appreciate the implications for other parts of my program - this thing runs asynchronously.) -- http://mail.python.org/mailman/listinfo/python-list
