Servlet Transport for Elasticsearch

The wares transport plugin allows to use the REST interface over servlets. You don't really install this plugin, but instead use the jar file in addition to elasticsearch itself in your web app using the maven repo:

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch-transport-wares</artifactId>
    <version>2.6.0</version>
</dependency>

Tomcat configuration (CORS filter)

The Tomcat configuration to allow CORS is:

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

Node resource

The node is registered as a servlet context attribute under elasticsearchNode so it is easily accessible from other web resources if needed.

You can also preregister your own node using elasticsearchNode servlet context attribute. It will be used by the NodeServlet.
