Error on connecting to JCR using JcrUtils.getRepositor

The call to Node root = session.getRootNode(); 

gives me the following error. Which I have been unble to resolve

Exception in thread "main" javax.jcr.RepositoryException: Unable to access a repository with the following settings:
    org.apache.jackrabbit.repository.uri: rmi://localhost:4502/crx/server
