Oak-jcr-0.9.jar, Oak-core-0.8.jar, oak-mongomk-0.8, oak-mongomk-0.9 by importing the com.mongodb.*, org.apache.jackrabbit.oak.*, and other corresponding packages

and i tried to create the node using the others site help like "http://experiencedelivers.adobe.com/cemblog/en/experiencedelivers/2013/12/starting_with_apacheoak.html" but the main issues is that after writting the code when i compile the code i am facing the problem like this

That blog post is about bootstrapping a new Oak instance. If you are using AEM, you already have an instance of Oak running. You should just use the JCR API to create nodes.

it is compile time issue & need to verify your code. Post your example.

            Repository repo = new Jcr(kernel).createRepository();           
            ContentRepository repository = new Oak().createContentRepository();*/
            Root root = new Oak().createRoot();
            Session session  =  repo.login(new SimpleCredentials("admin", "admin".toCharArray()));
            Node rootNode = (Node) session.getRootNode();
            ((javax.jcr.Node) rootNode).addNode("oakrocks", "nt:unstructured");
            session.save();

Iam using the above for node creation in mongodbmk and its giving me any compilation error and while executing the program its giving the error

Thanks,

Pavan

Hi Pavan,

  for AEM, you dont have to create a new repository as it will already be existing. you can just login, use the jcr api and create the nodes

import com.day.cq.commons.jcr.JcrUtil;

@reference

Session session;

 

session = repo.loginAdministrative(null);
Node root = session.getRootNode();

boolean nodeCheck = root.hasNode(nodePath);

Node path = null;
if(!nodeCheck){
      JcrUtil.createPath(nodePath, NT_UNSTRUCTURED, NT_UNSTRUCTURED, session, true);
}
path = root.getNode(nodePath);
