So I have written a java app to make posting image galleries to our wordpress blog much easier. I had evaluated it on wordpress 2.0.8 orignally and it worked (and still does). On my development site, I am using 2.3.2 and can not seem to connect to the xmlrpc.php.
Also, I installed blogdesk and it can connect to the older (2.0.8) install, but it also fails when connecting to the 2.3.2 blog. It seems that something has changed with xmlrpc since blogdesk specifically seems to treat < 2.2 different than > 2.2 and I do not know what those changes are.
