Hello,

I wrote a Java program which should store data in Elasticsearch. I decided to use a transport client.

When I run the programm the first time, the document is indexed:

Output:  
Feb 02, 2016 4:46:49 PM org.elasticsearch.plugins.PluginsService   
INFORMATION: [Man-Spider] loaded [], sites []  
Name: Cluster [dman]  
Document created  
Index: library  
Type: article  
ID: AVKiqjWGpjGvtNa5kG9W

When I run this program a second time I get the following error:  
"Failed to deserialize response of type".  
Below the code and a part of the detailed error message.

Does somebody know why this error occurs?

import java.io.IOException;  
import java.net.InetAddress;

import org.elasticsearch.action.index.IndexResponse;  
import org.elasticsearch.client.Client;  
import org.elasticsearch.client.transport.TransportClient;  
import org.elasticsearch.common.settings.Settings;  
import org.elasticsearch.common.transport.InetSocketTransportAddress;

public class docman {

```
public static void main(String[] args) throws IOException {

    Settings settings = Settings.settingsBuilder()
            .put("cluster.name", "dman").build();
    Client client = TransportClient.builder().settings(settings).build()
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    String json = "{" +
            "\"Title\":\"Mytitle\"," +
            "\"Doc\":\"Mydoc\"" +
            "}";
    
    IndexResponse iresponse = client.prepareIndex("library", "article")
            .setSource(json)
            .get();
    
    String _index = iresponse.getIndex();
    String _type = iresponse.getType();
    String _id = iresponse.getId();
    boolean created = iresponse.isCreated();
    
    if (created == true) {
        System.out.println("Document created");
        System.out.println("Index: " + _index);
        System.out.println("Type: " + _type);
        System.out.println("ID: " + _id);
    } 
    
    client.close();
    
}

```

}

You have to add the lzf jar to the class path. Check Elastisearch pom.xml for required dependencies.

```auto
         <dependency>
                <groupId>com.ning</groupId>
                <artifactId>compress-lzf</artifactId>
                <version>1.0.2</version>
            </dependency>

```

Great! This simple action solved the problem.

Thanks a lot! 🙂
