Using graphs in java : cient creation error

Elastic Stack Elasticsearch
1

Hello,

I'm currently testing the graph api offered by X-pack.
I could toy a bit with it using kibana, and wanted to test using it in my java application

However, I'm stuck at the creation of the PreBuiltXPackTransportClient.

Here's the creation code :

  Settings settings = Settings.builder()
          .put("cluster.name", "mycluster").build();

  TransportClient client = new PreBuiltXPackTransportClient(settings);
  try {
  	client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("myhost"), 9301));
  } catch (UnknownHostException e) {
  	// TODO Auto-generated catch block
  	e.printStackTrace();
  }

I'm getting this chain of errors

However, I disabled x-pack security on my cluster.
I do not understant why the client creation fails at a password verification if I do not have any security.

The version I'm using is 5.5.1.

Can anyone help me with any info on what I might be doing wrong?
Thanks.

That error is referring to the password for your truststore.
Is your application running with a system wide truststore defined? E.g. are you setting the javax.net.ssl.trustStore system property?

Hello, and thanks for answering.

Yes, that property is set.

It's set as a VM argument.
And I tried to set it via System.setproperty as well, but still to no avail.

Well then you need to unset it, or also set the password for the truststore as a system property.

If you run X-Pack with a system truststore then it needs the password too.

Thanks for the answer, and sorry for the delay.

Yes, I get it, and that solves my problem.
Thanks a lot.
