One option is to use jython (Python written in Java).

If that's not appropriate, you can fork/exec your script process using Runtime.exec(). Using this can be a bit fiddly, however - check out this article for common gotchas.

Runtime.getRuntime().exec("python script_name.py")

In addition to jython, python.org lists also Jepp as a possible choice.

I think JPype isn't here the right choice. JPype is "Java in Python", not "Python in Java". But Jepp (jepp.sourceforge.net) would be work like expected.
