An important point to note is that there is no json module in jython 2.5, because it was not introduced into cpython until 2.6.
So jython 2.7 has a json module.
If you cannot move to 2.7, I published a jython specific json module, called Jyson, which has a very similar interface to the json module.
Which will be much faster then the json module, on both 2.5 and 2.7, since it is written in native java.
