How to run jar files in python

Question

How can I call this jar from python and also capture the results:

c:> java -cp "C:\mallet-2.0.7\class;C:\mallet-2.0.7\lib\mallet-deps.jar" cc.mallet.fst.SimpleTagger --model-file nouncrf sample.txt

Like any other shell command. http://stackoverflow.com/questions/89228/calling-an-external-command-in-python — David Ehrmann, Feb 27 '14 at 17:13
@DevEx I think others might find this question via google, so I answered it below. Does that resolve your problem? — Uli Köhler, Feb 27 '14 at 17:51

Use subprocess:

from subprocess import call
call(["java", "-jar", "foo.jar"])

You could also add other arguments like -cp to the list:

call(["java", "-cp", "<yourclasspath>", "-jar", "foo.jar"])
