**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):
**Describe the issue** :
Using the Java client I want my app to be able create and configure the index. I want to load an explicit mapping from file. The simple problem is, I don’t seem to be able to create the TypeMapping object properly - it always looks empty and my index is created with dynamic mapping.
I’ve tried creating the transport with and without a provided mapper, I’ve even tried adding additional modules, which I think are unnecessary.
```auto
ObjectMapper mapper = JsonMapper.builder()
.addModule(new Jdk8Module())
.addModule(new JavaTimeModule())
.build();
// Create Transport
transport = ApacheHttpClient5TransportBuilder.builder(host)
.setHttpClientConfigCallback(httpClientBuilder -> {
final PoolingAsyncClientConnectionManager connectionManager = PoolingAsyncClientConnectionManagerBuilder
.create()
.build();
if (credentialsProvider != null) {
httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
}
return httpClientBuilder.setConnectionManager(connectionManager);
})
.setMapper(new JacksonJsonpMapper(mapper))
.build();
client = new OpenSearchClient(transport);
```
I then try to create the index with a TypeMapping, parsing my mapping.json from a valid inputStream:
```auto
JsonpMapper mapper = client._transport().jsonpMapper();
JsonProvider provider = mapper.jsonProvider();
JsonParser parser = provider.createParser(getMapping());
TypeMapping mapping = new TypeMapping.Builder().withJson(parser, mapper).build();
CreateIndexRequest createIndexRequest = new CreateIndexRequest.Builder().index(site.getIdentifier())
.mappings(mapping).build();
CreateIndexResponse createIndexResponse = client.indices().create(createIndexRequest);
```
Examing the `mapping` in the debugger shows it has no properties. I tested with a small example mappings.json from the docs with no luck. I get no errors; adding a deliberate error into mapping.json made no difference
Creating the index using `curl -X PUT /my-index -d @mapping.json` works

FYI I’ve tried this but still no luck:
` TypeMapping mapping = new TypeMapping.Builder().withJson(getMapping()).build();`

@jperrin, could you share an example of your mapping.json?

@pablo hi, thanks for your interest. As mentioned, I’ve tested with a small example `mapping.json` from the docs and that does nothing either. For completeness, this is the mapping I’m using, which works fine if I submit it using curl.

This part is adding mappings. However, in your JSON file you’re wrapping with mappings. As a result you will get mappings.mappings, which is incorrect.
Like running your curl with the following.
```auto
curl -X PUT /my-index/mappings -d @mapping.json
```
Try removing mappings wrapper.

Thanks Pablo, that makes sense and fixes the problem.
