I'm trying to update a nested object in Elasticsearch via the Java API, using a technique similar to what is outlined [here](http://stackoverflow.com/questions/18360225/elastic-search-is-it-possible-to-update-nested-objects-without-updating-the-ent). The problem is how to pass the json into the script. If I just blindly concatenate the json to the script string as suggested [here](http://stackoverflow.com/questions/23363801/update-nested-field-in-an-index-of-elasticsearch-with-java-api), the Groovy does not compile. If you pass it in directly as a parameter, it just gets parsed as a string. If I try to use JsonSlurper, like:

```auto
String script = "ctx._source.pete = new groovy.json.JsonSlurper().parseText(json)";
Map<String, Object> params = ImmutableMap.of("json", json);
return new Script(script, ScriptService.ScriptType.INLINE, null, params);

```

I get a compilation exception: unable to resolve class groovy.json.JsonSlurper

A further problem with the JsonSlurper approach seems to be that the Elasticsearch team has basically [disabled](https://github.com/elastic/elasticsearch/pull/16808) it in 2.2.

Does anyone know how to pass the json in correctly via the Java API?

Thanks to the guys at Elasticsearch for helping me with this. The answer is to convert the JSON to a `Map` and then just pass the `Map` as a param:

```
String script = "ctx._source.pete = jsonMap";
Map<String, Object> jsonMap = new ObjectMapper().readValue(json, HashMap.class);
Map<String, Object> params = ImmutableMap.of("jsonMap", jsonMap);
return new Script(script, ScriptService.ScriptType.INLINE, null, params);

```

I'm using `org.codehaus.jackson.map.ObjectMapper` to do the conversion from JSON to the `Map`.
