I'm trying to deploy this example
import javax.jcr.Repository; 
import javax.jcr.Session; 
import javax.jcr.SimpleCredentials; 
import javax.jcr.Node; 
import org.apache.jackrabbit.core.TransientRepository; 
/** 
 * Second hop example. Stores, retrieves, and removes example content. 
 */ 
public class Fish {
static Repository repository;
public static void main(String[] args) {
    Session session = null;
    try {
        repository = getRepositoryHandle();
        SimpleCredentials simpleCredentials = new SimpleCredentials(
                "username", "password".toCharArray());
        session = repository.login(simpleCredentials);
        Node root = session.getRootNode();
        Node hello = root.addNode("Olá");
        Node world = hello.addNode("Mundo");
        world.setProperty("Message", "olá mundo");
        session.save();
        Node node = root.getNode("Olá/Mundo");
        System.out.println(node.getPath());
        System.out.println(node.getProperty("Message").toString());
        root.getNode("Olá").remove();
        session.save();
    } catch (Exception e) {
        throw new RuntimeException(e);
    } finally {
        if (session != null)
            session.logout();
    }
}
private static Repository getRepositoryHandle() {
    if (repository == null)
        repository = new TransientRepository();
    // "classpath:repository.xml", "target/repository");
    return repository;
}
}

When I deploy it on eclipse, I get following errors and exceptions:
Exception in thread "main" java.lang.RuntimeException: javax.jcr.LoginException: LoginModule ignored Credentials
    at recipe.Fish.main(Fish.java:38)

Can someone help me with this issue, please ?
Thanks in advance.
