Hi, I am new to elastic search and having problem in connecting the node with Java API. Settings settings = ImmutableSettings.settingsBuilder() .put("cluster.name", "elasticsearch").build(); Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9200)); I am trying to get the node and create the index on it with this code. And I am getting Exception on nettyLayer.. Where when it using httpput , I am able to get the index created. HttpPut httpPut = new HttpPut("[http://localhost:9200/data/big/1](http://localhost:9200/data/big/1)"); httpPut.addHeader("Accept", "application/json"); httpPut.addHeader("Content-Type", "application/json"); JSONObject json = new JSONObject(); json.put("name", "testing"); json.put("message", "adding new index"); StringEntity entity = new StringEntity(json.toString(), "UTF-8"); entity.setContentType("application/json"); ``` httpPut.setEntity(entity); HttpClient httpClient = new DefaultHttpClient(); HttpResponse response = httpClient ``` .execute(httpPut); Please help me out in this regard. -- ---

Why don't you use the real Java API instead of the REST API?

I am using JAVA API and getting the exception , where if I use rest framework, it works fine.

Hi Ali, What Robin means to say is that you should be using the Elasticsearch Java API, and not use other REST/web libraries, even if they are in Java. There is no need for HttpPut, HttpClient, etc... Simple use the methods defined in org.elasticsearch.client.Client. The guide could do a better job at providing a front to back usage of the client object, but the basics are there. Take a look at creating an index using the Java API: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. The mailing list has tons of examples, and while it might be hard to search for code, you should still find something. Hopefully this can be a start.

The Java TransportClient Service is using port 9300, not 9200. For a quick example, see one of kimchy's gists [gist:2513321 · GitHub](https://gist.github.com/2513321) Hope this helps, Jörg On Tuesday, September 18, 2012 6:43:01 PM UTC+2, ali ilyas wrote: > Hi, > I am new to Elasticsearch and having problem in connecting the node with > Java API. > Settings settings = ImmutableSettings.settingsBuilder() > .put("cluster.name", "elasticsearch").build(); > Client client = new > TransportClient(settings).addTransportAddress(new > InetSocketTransportAddress("localhost", 9200)); > I am trying to get the node and create the index on it with this code. > And I am getting Exception on nettyLayer.. > Where when it using httpput , I am able to get the index created. > HttpPut httpPut = new HttpPut("[http://localhost:9200/data/big/1](http://localhost:9200/data/big/1)"); > httpPut.addHeader("Accept", > "application/json"); > httpPut.addHeader("Content-Type", > "application/json"); > JSONObject json = new JSONObject(); > json.put("name", "testing"); > json.put("message", "adding new index"); > StringEntity entity = new > StringEntity(json.toString(), "UTF-8"); > entity.setContentType("application/json"); > > ``` > httpPut.setEntity(entity); > HttpClient httpClient = new > > ``` > > DefaultHttpClient(); > HttpResponse response = httpClient > .execute(httpPut); > Please help me out in this regard. -- ---

use [JEST](https://github.com/searchbox-io/Jest) if you really want to some of the functionality of Apache HttpClient. In a project, i had a need to send custom headers, JEST had that capability plus the query building of the regular ES client API. ---
