Answer 1

This worked for me:

List jsonCategories = new ArrayList();

JSONObject jsonCategory = null;

for (ICategory category : categories) {
    jsonCategory = new JSONObject();
    jsonCategory.put("categoryID", category.getCategoryID());
    jsonCategory.put("desc", category.getDesc());
    jsonCategories.add(jsonCategory);
}
try {
    PrintWriter out = response.getWriter();
    response.setContentType("text/xml");
    response.setHeader("Cache-Control", "no-cache");
    _log.info(jsonCategories.toString());
    out.write(jsonCategories.toString());

} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
