Previous digest authentication with same nonce failed, returning null

[AlexTo]

Hi, I am using marklogic-jena:3.0.5 with Spring Boot

My Spring service looks like this

@Service
public class TripleStoreMarkLogicImpl implements TripleStore {

    private MarkLogicDatasetGraph dg;

    public TripleStoreMarkLogicImpl(MarkLogicConfig cfg) {
        DatabaseClient client = DatabaseClientFactory.newClient(
                cfg.getHost(),
                cfg.getPort(),
                new DatabaseClientFactory.DigestAuthContext(cfg.getUser(), cfg.getPassword()));

        this.dg = MarkLogicDatasetGraphFactory.createDatasetGraph(client);
    }

    public void insert(String graph, Model model) {
        Dataset ds = dg.toDataset();
        if (!ds.containsNamedModel(graph)) {
            ds.addNamedModel(graph, ModelFactory.createDefaultModel());
        }
        Model g = ds.getNamedModel(graph);
        g.add(model);
    }
    // more code
}

If I use Postman to post to my Controller which then calls my Service, it works fine. However, when I deploy in the test environment with higher load, then I have the below error message. It seems to be related to this issue java-client-api-#770 but according to the status, the issue has been fixed. :(

Btw, how do I properly create and close the connection? Do I create and close inside the insert() method or should I create the connection in the service constructor like what I am doing now?

Thanks

Hello, you need a release of marklogic-jena that has an upgraded java client. I'll raise this issue and see about cutting a release as soon as is convenient. Feel free to ping back if you don't hear a reply.

Your connection method should be good. It's intended to be a long-lived object.

Thanks a lot for a quick update, I look forwards to the next release. Regards

Any update on release? Having similar problem with similar setup. But instead of fail I see:

o.OkHttpClient : previous digest authentication with same nonce failed, returning null o.OkHttpClient : Cached authentication expired. Sending a new request.

if you can't wait for MarkLogic to release the new version, simply clone the Git and update this file

https://github.com/marklogic/marklogic-jena/blob/master/marklogic-jena/build.gradle

1. Update marklogic-client-api version from 4.0.3 to 4.1.1
2. Update version from 3.0.5 to 3.0.5.1 (just to avoid conflicting in Maven repo)
3. Rebuild the project or install into local Maven repo according to the instructions

I no longer have errors after bumping marklogic-client-api to latest version

Thanks for reply!
