Hi there,
I'm using a python script in conjunction with a JPype, to run java classes.
So, here's the code:
from jpype import *
import os
import random
import math
import sys
input = open('foo.img', 'rb').read().de code('ISO-8859-1')
square = java.encoding(i nput)
output = java.decoding()
fd = open('foo_decod e.img','wb')
fd.write(output .encode('ISO-8859-1'))
fd.close()
sys.exit(0)
First of all, java.encoding and java.decoding are two methods that
respectively take a java string as an argument and return a java String.
JPype is the bridge between Java and Python, and converts automatically
a str or unicode pythonstring into a Java String.
So, input and output are two unicode strings. I were forced to use
decode() and encode() methods by python, otherwise it refuses to read
foo.img file.
Here's the strange behaviour: when I write the output in the
'foo_decode.img ', I don't reassemble the original file; I already tested
the java encoding/decoding libraries with the same input file, and what
the decoding process returns is the original file.
I suspect that the discrepancy is due to encoding/decoding of
ISO-8859-1: is that required?
What do you think about?
Thank you
