Hi,

I am stuck in importing JAVA libraries to Python.

1. How do I import JSON?
I tried using simplejson with SFS Python, but its throwing some errors. So I didnt want to use external libs and wanted to use core JAVA libs. Is there a way I can directly import Java's JSON Classes? I have copied json-lib into the lib directory and when I am trying to import the classes using Its not importing it, it says no module name json.

I am using eclipse to test and tried putting all the jars in the library path and class path too but to no avail.

2. For connecting to my Mysql DB. Do I have to use hibernate or can I use normal jdbc dirver to connect to my DB server. If so, if someone can give me a code snippet of how to import it, it would be great.

Thirdly, if I create a singleton class to run in an extension, will the same object be used if I use the class in another extension? Or since its a threaded execution will there be any difference?
Thank You.

It should be:
from org.json import JSONObject, JSONArray

Then you can use them directly in your Python code.

Here are the docs:
http://www.json.org/javadoc/org/json/JSONObject.html
http://www.json.org/javadoc/org/json/JSONArray.html

p.s. = native Python libraries won't work in Jython unless they are written in pure Python. In any case you'll need the sources to use them. The C-Python bytecode is not compatible with Jython

As I mentioned above, I tried using simplejson and it throws an error which says 'invalid syntax' near 'yield'.

After some digging, I came to know that 'yield' doesnt work in Jython 2.1.

So the best way to do this is us
At the beginning of the file (not anywhere else).

And everything works like a charm.

And coming down to org.json import, eclipse is unable to show some classes in the interface otherwise org.json works perfectly fine!
