I've deployed a Neo4j unmanaged extension. The unmanaged extension can be called using REST Client and successfully returned the result. The problem is when I try to call / invoke the unmanaged extension from another java class, it keep on throwing the 401 Unauthorized.

I used Spring RestTemplate to invoke the unmanaged extension.

My codes :

RestTemplate restTemplate = new RestTemplate();
PostPhotoRest postPhotoRest = restTemplate.getForObject("http://myneo4jusername:myneo4jpassword@localhost:7474/extension/servicetwo/postphoto/55b12d35-94fd-4297-bb18-e6040d7b7109", PostPhotoRest.class);

Full Error :

  • do you send any authorization details through rest client? – sidgate Jul 18 '16 at 08:10
  • @sidgate : yes, username & password – shkhssn Jul 18 '16 at 08:19

  • thanks @sidgate! it's working now as I passed the authentication via header. I just wondering is it possible to use the existing **ogm.properties** that I already configure for my Spring Data Neo4j? If I use authentication via header as for now, I need to maintain the authentication info in two places - ogm.properties and header. – shkhssn Jul 19 '16 at 02:06

The driver configuration can supply the URI and credentials configured in ogm.properties.

Components.driver().getConfiguration().getURI();
Components.driver().getConfiguration().getCredentials();
