I'm using `elasticsearch` (v5.0.0) in java application. I can't find `writeValueAsBytes()` function.

But [Java Api](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-docs-index.html) have similar example.

This is all functions in `ObjectMapper` class:

Hi @kevinZ,

you are using `org.elasticsearch.index.mapper.ObjectMapper` instead of `com.fasterxml.jackson.databind.ObjectMapper`. You need to add the following dependency to your project's `build.gradle` file:

```auto
compile "com.fasterxml.jackson.core:jackson-databind:2.8.1"

```

(See [mvnrepository.com](http://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.8.1) for the syntax of other build systems).

Unfortunately, the docs fail to mention that; we'll correct it. Thanks for spotting it.

Daniel
