Someone knows How can I install jython or Jpython in a raspberry pi on raspbian? because I search but there is nothing clear.

  • why do you need jython, when you can use full-fledged python? – lenik May 20 '14 at 15:15
  • @lenik: because with jython you are able to use Java Libraries inside your "Python" programm because it is executed in the JRE. – Simulant May 21 '14 at 9:06

according to this command:

$ apt-cache search jython
jython - Python seamlessly integrated with Java
jython-doc - Jython documentation including API docs

you may install jython on Raspberry Pi by running:

$ sudo apt-get install jython

however jython on raspberry is very slow, here's a quote from google groups:

$ time python hello.py
Hello, World
platform is linux2

real    0m0.211s
user    0m0.160s
sys    0m0.040s
$ time jython hello.py
Hello, World
platform is java1.7.0_40

real    0m35.639s
user    0m33.830s
sys    0m1.420s

Yes, that's right. 35 seconds to say "Hello, World".

  • Most of that time is the JVM starting up. For any application with a bit more meat than hello world, the timings would be more realistic. – user30937 May 16 '15 at 21:55
