This should do the trick. If you look at the subprocess documentation you can see that check_output runs a command with arguments and return its output as a byte string.

import multiprocessing as mp
import subprocess

command = "java -jar /home/myfolder/collect.jar"

def runCommand(q):
 commandOutput = subprocess.check_output(command.split()).decode("utf-8")
 q.put(commandOutput)

q = mp.Queue()
commandProcess = mp.Process(target=runCommand, args=(q, ))
commandProcess.start()
output = q.get()
print(output)
with open('collect.json', w) as fp: 
 fp.write(output)

Didn't run the code, but should work.

You can try something like this

with open('collect.json','w') as fp :
 subprocess.Popen('java -jar .//home/myfolder/collect.jar',stdout=fp).wait()

for further information, see this question How to get the output from .jar execution in python codes?
