title: Create index in Elastic Search by Java API
body: <p>I used following code for creating index in Elastic Search,
  Default JAVA API:</p>
  
  <pre><code>Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "myClusterName").put("client.transport.sniff", true).build();
  Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
  CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate("test1");
  CreateIndexResponse response = createIndexRequestBuilder.execute().actionGet();
  System.out.println(response.isAcknowledged());  
  </code></pre>
  
  <p>REST Service:</p>
  
  <pre><code>HttpURLConnection con = null;
  try
  {
      String url = "http://localhost:9200/test2";
  
      URL resturl = new URL(url);
      con = (HttpURLConnection) resturl.openConnection();
  
      con.setDoOutput(true);
      con.setRequestMethod("PUT");
      BufferedReader in = null;
      try
      {
          if (con.getInputStream() != null)
          {
              in = new BufferedReader(new InputStreamReader(con.getInputStream()));
          }
      }
      catch (IOException e)
      {
          if (con.getErrorStream() != null)
          {
              in = new BufferedReader(new InputStreamReader(con.getErrorStream()));
          }
      }
      if (in == null)
      {
          throw new Exception("Unable to read response from server");
      }
      StringBuffer decodedString = new StringBuffer();
      String line;
      while ((line = in.readLine()) != null)
      {
          decodedString.append(line);
      }
      in.close();
      System.out.println("4");
      Integer responseCode = con.getResponseCode();
      System.out.println(responseCode);
  }
  catch (Exception ex)
  {
      ex.printStackTrace();
  }
  finally
  {
      if (con != null)
      {
          con.disconnect();
      }
  }
  </code></pre>
  
  <p>By using REST API, I am able to create index. By default JAVA API, 
  I am getting the following Exception. </p>

  <p>Please guide me where I made mistake. Thanks in advance</p>
