POST JSON,Create File within application

[Nequita Geldenuys]

Hey All

I am currently new to development and lucky for me I got assigned to start with blackberry first.. I have a 2 queries so if anyone has help, advice, Snippets, links, i would be much appreciative.

1. I am unable to successfully post JSON and I have found nothing on the net that could help me.

2. I want to put a "add File" function on to my application(So the user will select the "new Folder" menu item, enter a name and click the save button) I have got the following link can someone tell me if this is the right way to be creating folder options? http://docs.blackberry.com/en/developers/deliverables/17952/Creating_a_folder_1554347_11.jsp

Then If it is, I want to automatically get the directory of the app for the folder to be saved in, please help I am completely off of track with this!!

Thank you
