services xmlrpc

Im looking for help on how to add taxonomies and files to nodes using Java and XMLRPC:

• add taxonomy terms to a node (using term reference fields)
  this is what i got: {field_area={und={0={tid=38}}}...} and its not adding the term to the created node

• add files to a node

• edit/update existing nodes

i cant get anything to work and there's little documentation about how to use the API (which parameters requested etc)

anyone help?

I have written a javascript application that will post comments to any node in my local drupal install with and API key. The goal is to be able to use an android/iPhone mobile PhoneGap applicaiton to post content to a Drupal server.

My question is can I add topics to a Forum using the services XMLRPC interface?

I can add a node of type "forum" however that never show up in the forum.

I currently using services v2 on Drupal v6.2.2 server.

Here a simple JavaScript code snippet:

function postForumTopic(intNode,strText){
    var method = "node.save";

I have setup an endpoint called api.
It uses an xmlrpc server.
I have enabled system.connect in the resources tab.
I send this request:
