Hi can any body give me the code or steps to communicate elasticsearch  
using java.I ahve already created one example,but i am not able to  
understand what it is doing, is there any source code or step by step  
creation of example in eclipse Using Transoprt Client as well as Node .

here is the code which i found in google and try to execute.

import java.util.Date;  
import java.util.HashMap;  
import java.util.Map;

import org.elasticsearch.client.Client;  
import org.elasticsearch.node.Node;

import static org.elasticsearch.node.NodeBuilder.\*;

public class PostES {

```
public static void main (String args[]){
    PostES p = new PostES();
    p.postElasticSearch();
}

public static Map<String, Object> putJsonDocument(String title, String 

```

content, Date postDate, String author){

```
        Map<String, Object> jsonDocument = new HashMap<String, 

```

Object\>();

```
        jsonDocument.put("title", title);
        jsonDocument.put("conten", content);
        jsonDocument.put("postDate", postDate);
        jsonDocument.put("author", author);

        return jsonDocument;
}

private void postElasticSearch(){

        Node node = nodeBuilder().node();
        Client client = node.client();

        client.prepareIndex("testindex", "article")
                  .setSource(putJsonDocument("Example Title",
                                             "This description is so 

```

important. You dont even know!",  
new Date(),  
"J.R."))  
.execute().actionGet();

```
        node.close();
    }

```

}

and i am getting errors as

I think your class path is incorrect and does not have all needed libs (Lucene here)

Well. It depends on how you created your project.  
Are you using Maven?  
Are you running your program from a command line, from an IDE?

Hi David,i will make it simple.My main moto is using java i want to do CRUD  
operations with Elasticsearch,in this process i came to know about  
Elasticsearch related Java  
Api's URL :

> **[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.

,from this i followed the steps as it is starting from Maven to Client  
Api.I am using Eclipse Kepler and created WebDynamic Project and build the  
respective jars,and copied the code from Client Api(Node based and  
TransportClient) and execute using JavaApplication i.e.main() which uses  
console app i.e. eclipse cmd. so,for now am trying atleast to connect to  
Elasticsearch ,after getting this then i will move on with CRUD operations  
using JSON. ANY GUIDANCE GIVEN WILL BE HIGHLY APPRECIATED.

URGENT REQUIREMENT.  
Thanks in advance.

You don't have to repeat yourself and open many threads for the same thing.

Let me focus on elasticsearch. I'm not going to answer about your IDE and how you should setup java applications.

If you are using Maven (recommended), you just need to follow what we wrote here: [http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/\_maven\_repository.html](http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/_maven_repository.html)

Add a dependency like:  
  
org.elasticsearch  
elasticsearch  
1.0.1

If you are not using Maven, you need to add elasticsearch-1.0.1.jar and all its non-shaded dependencies which are listed in our pom.xml [1] to your class path (project class path in eclipse - Java class path if you launch your application from command line).

For example:  
  
org.apache.lucene  
lucene-core  
4.6.1

[1] [http://search.maven.org/remotecontent?filepath=org/elasticsearch/elasticsearch/1.0.1/elasticsearch-1.0.1.pom](http://search.maven.org/remotecontent?filepath=org/elasticsearch/elasticsearch/1.0.1/elasticsearch-1.0.1.pom)

Hi David,i will make it simple.My main moto is using java i want to do CRUD operations with ElasticSearch,in this process i came to know about ElasticSearch related Java  
Api's URL : [http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/index.html](http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/index.html) ,from this i followed the steps as it is starting from Maven to Client Api.I am using Eclipse Kepler and created WebDynamic Project and build the respective jars,and copied the code from Client Api(Node based and TransportClient) and execute using JavaApplication i.e.main() which uses console app i.e. eclipse cmd. so,for now am trying atleast to connect to Elasticsearch ,after getting this then i will move on with CRUD operations using JSON. ANY GUIDANCE GIVEN WILL BE HIGHLY APPRECIATED.

URGENT REQUIREMENT.  
Thanks in advance.

Hi can any body give me the code or steps to communicate elasticsearch using java.I ahve already created one example,but i am not able to understand what it is doing, is there any source code or step by step creation of example in eclipse Using Transoprt Client as well as Node .

here is the code which i found in google and try to execute.

        Map<String, Object> jsonDocument = new HashMap<String, Object>();

        jsonDocument.put("title", title);
        jsonDocument.put("conten", content);
        jsonDocument.put("postDate", postDate);
        jsonDocument.put("author", author);

        return jsonDocument;
}

private void postElasticSearch(){

        Node node = nodeBuilder().node();
        Client client = node.client();

        client.prepareIndex("testindex", "article")
                  .setSource(putJsonDocument("Example Title",
                                             "This description is so important. You dont even know!",

                                             .execute().actionGet();

        node.close();
