如何在python中运行jar文件

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

Answer 1

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"])
