As you said, Yes, I have already seen that platform,py is in CPythonLib and
significant work has been done in it.
I imported and tested platform module.
The output:
test_architecture (__main__.PlatformTest) ... ERROR
test_dist (__main__.PlatformTest) ... ok
test_java_ver (__main__.PlatformTest) ... ('1.5.0', 'IBM Corporation', ('IBM J9 VM', '2.3', 'IBM Corporation'), (None, None, None)) ok

and it is not recognizing the actual underlying OS. its recognizing Java
as OS and retrives the details. From the above example it could be clear
for you.
In CPython implementation, there are 5 functions which are not
required for Jython . they are python specific functions.
1. libc_ver()
2. python_build()
3. python_compiler()
4. python_version()
5. python_version_tuple()
In the platform patch, those functions had been replaced with
a. jython_compiler()
b. jython_version()
c. jython_version_tuple()

which actually matches the output of all the cpython platform module.
The actual problem is, its not recognising the actual OS( Linux,Mac,Win
etc) instead it recognizes java vm as platform and retrieves the values
of it.
we have reused most of the code from the cpython platform module and it
had been modified properly.
To make the module sync up with the CpythonLib
1. we import platform from the CPythonLib to a new class and then
tailoring the new class (but the module name will get changed)
2. we can generate the platform module by copying the important
working CpythonLib platform module and with our functions.
3. we will rewrite everything in .java files
currently I am able to think of these solutions only..
I am sorry for ripping out the attribution and copyrights
from the previous authors.
please send if there is any better way of doing this.
