Namespace prefix by is not mapped to a namespace URI

[st1ll]

Hello.
When I try to run simple code to add a node (custom model type), I get stacktrace:

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

Code of client:

       Repository repository = (Repository)context.getBean("JCR.Repository");   
       Session session = repository.login(new SimpleCredentials("admin", "123".toCharArray()));
   
       try
       {
           // first, access the company home
           Node rootNode = session.getRootNode();
           Node companyHome = rootNode.getNode("app:company_home");
   
           // create the content node
           String name = "JCR sample (" + System.currentTimeMillis() + ")";
           Node content = companyHome.addNode("by:" + name, "by:log");
               …

On last line a get an exception.

In UI all work fine, I can add, edit documents with this model. But not work, when I try to programmaticly add content.

Excuse me for my bad English

Hello,

Are you running your FirstJCRClient application in the same application context as the repository you deployed your model in? As far as I know the FirstJCRClient locally starts an embedded repository and I assume your model is not deployed in that one, causing the error from your stacktrace.
