Windows Live Writer fail to do updates - solved 

                 Key: ROL-1811
             Project: Roller
          Issue Type: Bug
          Components: Web Services
    Affects Versions: 4.0.1
            Reporter: Steven Board
            Assignee: Roller Unassigned
            Priority: Minor

Hi Guys, 

I know you're aware that Windows Live Writer is unable to perform updates to roller blogs
using the xml rpc, however I thought I would let you know why and how I fixed it locally incase
you wanted to apply this fix to the next release of roller.

The reason the update to blogs fails is actually due to the org.apache.roller.weblogger.webservices.xmlrpc.MetaWeblogAPIHandler.getCategories
method actually having two bugs.

The first is trivial and is the fact that you pass the userId to the MetaWeblogAPIHandler.createCategoryStruct(WeblogCategory
category, String userid) method, rather than the blogId.  The createCategoryStruct method
then incorrectly creates the rssUrl and htmlUrls.

The second is the fact that the getCategories method does not comply with the MetaWeblog API.
 The method you have created returns a Hashtable with the categories as keys with the values
being another Hashtable as defined by the MetaWeblog API for the getCategories method.  The
getCategories should just return the values from the currently returned Hashtable as a List.

e.g. The getCategories method should be something like the below.

	public Object getCategories(String blogid, String userid, String password)
			throws Exception {
				.debug("STEVEN BAORD custom getCategories() Called =====[ SUPPORTED ]=====");
		mLogger.debug((new StringBuilder()).append("     BlogId: ").append(
		mLogger.debug((new StringBuilder()).append("     UserId: ").append(
		Weblog website = validate(blogid, userid, password);
		Weblogger roller = WebloggerFactory.getWeblogger();
		try {
			WeblogManager weblogMgr = roller.getWeblogManager();
			List cats = weblogMgr.getWeblogCategories(website, false);
			ArrayList<Hashtable> result = new ArrayList<Hashtable>();
			WeblogCategory category;
			Iterator wbcItr = cats.iterator();
			while (wbcItr.hasNext()) {
				category = (WeblogCategory);
				result.add(createCategoryStruct(category, blogid));
			return result;
		} catch (Exception e) {
			String msg = "ERROR in MetaWeblogAPIHandler.getCategories";
			mLogger.error(msg, e);
			throw new XmlRpcException(1000, msg);

For anyone else wanting to fix this locally you also need to set the site.absoluteurl property
in the roller_properties tables within the database to the url for your roller instance. 
e.g. http://<your-domain>/roller.  This is to make sure that the rssUrl and httpUrl
for the categories are correctly created with their full paths.
