[preface]
== Preface
This section describes the Java API that elasticsearch provides. All
elasticsearch operations are executed using a
<<client,Client>> object. All
operations are completely asynchronous in nature (either accepts a
listener, or returns a future).

Additionally, operations on a client may be accumulated and executed in
<<java-docs-bulk,Bulk>>.

Note, all the APIs are exposed through the
Java API (actually, the Java API is used internally to execute them).


== Maven Repository

Elasticsearch is hosted on
http://search.maven.org/#search%7Cga%7C1%7Ca%3A%22elasticsearch%22[Maven
Central].

For example, you can define the latest version in your `pom.xml` file:

[source,xml]
--------------------------------------------------
<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>${es.version}</version>
</dependency>
--------------------------------------------------

== Deploying in JBoss EAP6 module

Elasticsearch and Lucene classes need to be in the same JBoss module.

You should define a `module.xml` file like this:

[source,xml]
--------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.elasticsearch">
  <resources>
    <!-- Elasticsearch -->
    <resource-root path="elasticsearch-2.0.0.jar"/>
    <!-- Lucene -->
    <resource-root path="lucene-core-5.1.0.jar"/>
    <resource-root path="lucene-analyzers-common-5.1.0.jar"/>
    <resource-root path="lucene-queries-5.1.0.jar"/>
    <resource-root path="lucene-memory-5.1.0.jar"/>
    <resource-root path="lucene-highlighter-5.1.0.jar"/>
    <resource-root path="lucene-queryparser-5.1.0.jar"/>
    <resource-root path="lucene-sandbox-5.1.0.jar"/>
    <resource-root path="lucene-suggest-5.1.0.jar"/>
    <resource-root path="lucene-misc-5.1.0.jar"/>
    <resource-root path="lucene-join-5.1.0.jar"/>
    <resource-root path="lucene-grouping-5.1.0.jar"/>
    <resource-root path="lucene-spatial-5.1.0.jar"/>
    <resource-root path="lucene-expressions-5.1.0.jar"/>
    <!-- Insert other resources here -->
  </resources>

  <dependencies>
    <module name="sun.jdk" export="true" >
        <imports>
            <include path="sun/misc/Unsafe" />
        </imports>
    </module>
    <module name="org.apache.log4j"/>
    <module name="org.apache.commons.logging"/>
