Hello everyone !!

I have written a scipt for a program called Javafoil and I want torun it from python.
I Therefore write this command in the python console :

java -cp "java\javafoil.jar;java\mhclasses.jar" "MH.JavaFoil.JavaFoil" Script=Script_Javafoil.jfscript

But I have an error :

Error:
java -cp "java\javafoil.jar;java\mhclasses.jar" "MH.JavaFoil.JavaFoil" Script=Script_Javafoil.jfscript
                                              ^
SyntaxError: invalid syntax

I have to admit that this command line was given to me and that I don't really get how it works ...
Can someone help and explain ?

Thanks a lot !!

You can try

>>> s = 'java -cp "java\javafoil.jar;java\mhclasses.jar" "MH.JavaFoil.JavaFoil" Script=Script_Javafoil.jfscript'
>>> import shlex
>>> command = shlex.split(s)
>>> import subprocess as sp
>>> sp.call(command)

Tanks Gribouillis !!

But when I run your code I get :

Error:
Error: Could not find or load main class MH.JavaFoil.JavaFoil

What's wrong ? Can you explain me the different parts of a command line such as : java -cp "java\javafoil.jar;java\mhclasses.jar" "MH.JavaFoil.JavaFoil" Script=Script_Javafoil.jfscript ? Maybe it could help ...

This is not a python question: your question is about the syntax of the java command. You could read this or type java -h
or man java in a terminal/console. The exact syntax may depond on your os. For example I read that in linux, the ; in your command must be replaced with :.
