Custom content types

[naveenkumar]

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

org.alfresco.service.namespace.NamespaceException: Namespace prefix dml is not mapped to a namespace URI

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).

hi derek i followed this link http://wiki.alfresco.com/wiki/Data_Dictionary_Guide#Step_4:_Register_the_Model_with_the_Repository for registering my custom content types. whats the diff in using example-model-context.xml.sample  and custom-model-context.xml.sample..both are same….

i found usage of custom content types is impossible through jcr api…
Please check here… http://wiki.alfresco.com/wiki/Data_Dictionary_Guide#Using_a_Custom_Model
