Unable to connect to CRX Server using JCR/JackRabbit

I am trying to access a CRX server over the internet using JcrUtils.getRepository method in JCR/JackRabbit and receiving the following error:

javax.jcr.RepositoryException: Unable to access a repository with the following settings:
  org.apache.jackrabbit.repository.uri: http://<<Server Name>>/crx/server
The following RepositoryFactory classes were consulted:
Perhaps the repository you are trying to access is not available at the moment.
at org.apache.jackrabbit.commons.JcrUtils.getRepository(JcrUtils.java:184)
at org.apache.jackrabbit.commons.JcrUtils.getRepository(JcrUtils.java:223)
at ReadContentRepositary.main(ReadContentRepositary.java:19) 

This is my code:

import javax.jcr.Repository;
import javax.jcr.Session;
import javax.jcr.SimpleCredentials;
import javax.jcr.Node;
import org.apache.jackrabbit.*;

import org.apache.jackrabbit.commons.JcrUtils;
import org.apache.jackrabbit.core.TransientRepository;

public class ReadContentRepositary {

public static void main(String[] args) {
// TODO Auto-generated method stub

try { 
//Create a connection to the CQ repository running on local host
Repository repository = JcrUtils.getRepository("http://<<Server Name>>/crx/server");

//Create a Session
javax.jcr.Session session = repository.login( new SimpleCredentials("admin", "admin".toCharArray()));

//Create a node that represents the root node
Node root = session.getRootNode();
System.out.println("Root Node Value is " + root.getIndex());

// Save the session changes and log out
//session.save();
session.logout();
}
catch(Exception e){
e.printStackTrace();
}
}

}
