I'm trying to connect from Java to ElasticSearch but I can only connect over HTTP. I can't use the TransportClient. Is there a Java client wrapper around the ElasticSearch REST APIs? If so, how do I use it?

I have the same issue, I have to be able to connect to a ES server over port 80 only. Jest looks nice, but unfortunately the Jest sample application is way behind the core Jest library.
A new "official" REST-based java client will be available starting with v5.0.0-alpha4.

We just open sourced Flummi, a Java HTTP/REST client for Elastic Search. It imitates the transport client's API as closely as possible, making it easy to port existing code. It also provides a better abstraction level than Jest, because it reports all the errors with Exceptions. Give it a try!
Simple usage example:
Flummi flummi = new Flummi("http://elasticsearch.base.url:9200");
SearchResponse searchResponse = flummi
.prepareSearch("products")
.setQuery(
QueryBuilders.termQuery("color", "yellow").build()
)
.execute();
System.out.println("Found "
+ searchResponse.getHits().getTotalHits()
+ " products");
searchResponse.getHits()
.stream().map(hit -> hit.getSource().get("name").getAsString())
.forEach(name -> System.out.println("Name: " + name));

Since version 5.6 of the Elasticsearch Java SDK they provide a Java REST Client.
RestClient restClient = RestClient.builder(
new HttpHost("localhost", 9200, "http"),
new HttpHost("localhost", 9201, "http")).build();
// for the RestHighLevelClient
RestHighLevelClient client =
new RestHighLevelClient(restClient);
