Hi,  
I am using Java REST APIs 5.1.1 for elasticsearch. I need to get the list of indexes on successful connection to elasticsearch using host, port, username, password.  
I am not able to get a list of available indexes.

Please help.

What have you tried? You can get a list of all indices with:

`curl -XGET "http://localhost:9200/_aliases"`

Hi @andrewkroh,

Sorry, it is my bad. Actually I got this command earlier. But I don't know how to call this using java rest APIs given.  
I am new in Java development. How to execute this from RestClient, or what is the way to call this and get result in java.

Thanks

Have you seen the examples [here](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/_example_requests.html)?

```auto
Response response = restClient.performRequest("GET", "/_aliases",
        Collections.singletonMap("pretty", "true"));
System.out.println(EntityUtils.toString(response.getEntity()));

```

Then you need to unmarshal the response.

Thanks @andrewkroh,  
It worked.  
Though I have been through the example requests page, but I think I missed that EntityUtils thing.

Thanks again.  
🙂
