I created my own content types, i want to use them while adding node using JCR API. lets take my content type is dml:rsscontent.
here is my java class.

Node rootNode = session.getRootNode();
         // first, access the company home
         Node companyHome = rootNode.getNode("app:company_home");
         Node rssFeeds = companyHome.getNode("app:user_homes");
         //To get items from rss feeds.                        
         // create the content nodegud morning
         Node channelContent = rssFeeds.addNode("cm:","dml:rsscontent");‍‍‍‍‍‍‍

while executing the above class i am getting this error

Hi,

You need to register a model that declares that namespace and the properties.  See the sample file custom-model-context.xml.sample.  (http://wiki.alfresco.com/wiki/Data_Dictionary_Guide).
